Cogeneration & On–Site Power Production | November - December 2013 www.cospp.com4

Capacity factors, utilisation factors and load factors

Modern power supply systems

increasingly need distributed

generation and, if possible,

cogeneration in order to

keep systems stable and electricity costs

acceptably low. This is, however, not clear

to everybody, especially in the case of the

average citizen (and most policymakers),

who are unfamiliar with capacity factors,

utilisation factors and load factors. One

often reads in the news, even in technical

magazines, that a newly installed wind

park produces suffcient electricity to cover

the energy demands of, say, 100,000

households. Most people have no idea that

such a message is misleading.

Firstly, fnal electricity use is only 12% of total

global energy use. Secondly, households

consume, on average, only 20% of the

electricity needs of a modern nation. Globally,

46% of electric energy supplied goes to industry

and the remaining 34% is for services. Using

only households as a criterion for covering

electricity demand gives an over optimistic

idea of such a wind park’s achievements.

Thirdly, wind parks’ output is variable and

cannot be relied on to cover a given demand.

One often sees so-called doldrums of up to

10 days, when the wind scarcely blows in a

widespread area. And the wind can blow so

hard in an area half the size of Europe that

90% of the installed wind turbines spin at

maximum output.

Solar photovoltaic (PV) panels also show

large output variability. They do not produce

at night, and have limited output in the darker

seasons. Backup power is required for these

renewable sources, and cogeneration and

distributed generation are the best options.

For a proper analysis of the need for

and benefts of local generators, we must

distinguish between capacity factors,

utilisation factors and load factors. There is no

common agreement yet on the defnitions

of these factors. In the old days, before the

introduction of volatile electricity generators,

some ambiguity in defnitions did not matter.

Today, however, exactness is crucial in order to

understand the implications of these factors.

As an example, in Germany the average

available output of the combined wind

turbine portfolio is about 20% of the installed

capacity. This means that the output of the

installed 32 GW is only 6.4 GW averaged

over a year. We can therefore defne the

capacity factor as the averaged unrestricted

output divided by the installed capacity. For

solar PV panels in Germany, the capacity

factor is around 10%. If wind turbines’ output

was noticeably curtailed, their so-called

utilisation factor would be lower than the

capacity factor. The utilisation factor of a

generator is the actual averaged output

divided by the installed capacity. The load

factor of a generator is the instantaneous

output divided by its nominal capacity.

Imagine a case of no renewables in a

system, while fuel-based generators have a

utilisation factor of 60%. The load factor might

vary between 100% and 60%. Now, volatile

renewable generators will be connected with

the same installed capacity as the fuel-based

generation. If the renewable generators have

a capacity factor of 15%, and their output is

not restricted, the utilisation factor of the fuel-

based generators will decrease from 60% to

45%. For large central power plants, this would

mean operational and fnancial disaster.

Distributed generation, however, can offer

the required fexibility. Its load factor can vary

widely. Because of its relatively low capital

costs, even a lower utilisation factor is not a

problem. So, it is essential to know all about

capacity factors, utilisation factors and

load factors.

Insight

Resource effciency reaches the Middle East

Might the Middle East – led

by Saudi Arabia and other

oil-producing states – eventually

emerge as a signifcant new

market for cogeneration and, perhaps,

wider decentralised energy technologies?

Oil refneries around the world are a prime

application area for cogeneration, often

producing ‘waste’ gases that can be used

as fuel, and having large process heat

loads that need to be met. Hot climates and

large-scale district cooling go together too,

although electricity generation is not always

involved here.

I was struck by the August announcement

that Saudi Aramco has signed agreements

with three companies to build and operate

cogeneration plants at three major oil and

gas complexes (Abqaiq, Hawiya and Ras

Tanura) in the oil-rich Kingdom. The proposed

plants will between them generate 900 MW

of power and provide 1500 tonnes of steam

per hour to the refneries from 2016. Aramco’s

partners, Marubeni, JGC and Aljomaih

Energy and Water, will build and then operate

the plants for 20 years. Cogeneration already

has a foothold in the country – earlier this

year, Aramco was reported to have signed

an agreement to expand three existing

cogeneration plants.

In textbook CHP-speak, Aramco’s

statement referred to the ‘high effciency in

energy consumption and environmental

performance’ of the proposed plants.

Marubeni called the contract the beginning

of a long-term relationship as the Kingdom

moves into a new phase of power effciency

and resource management.

In October, the president and CEO of

Saudi Aramco, Khalid Al-Falih, said at the

World Energy Congress in South Korea

that his company is working to increase

conventional oil recoveries to 70%, as well

as looking for new oil and gas resources. Al-

Falih also announced the development of a

1000 MW on-site power plant, to be fuelled by

unconventional gas reserves found recently

in the north of the country, to feed a massive

phosphate mining and manufacturing

centre. Not CHP this time, but on-site power.

On-site solar power? Saudi Aramco this

summer received the highest possible

accreditation under the Leadership in Energy

and Environmental Design (LEED) scheme for

its new Al Midra building, which incorporates

10 MW of solar PV panels shading its vehicle

parking areas and sized to meet the total

demand of the building.

District energy? Also this summer, Saudi

Aramco opened a new, CHP-based district

cooling plant to serve its headquarters and

other facilities in Dhahran. The plant has a

generation capacity of 35 MW of electricity

and 27,000 tonnes of cooling. Another district

energy scheme, located at a university

in Riyadh and based on solar thermal

technology, won a Global Climate Award at

a ceremony in New York in September.

District cooling is booming around parts

of the Middle East and both the UAE and

Saudi Arabia also have ambitious plans for

developing renewable energy resources.

It’s clear that, with the best days of the

oil and gas boom now coming to an end,

resource effciency is becoming important

to oil-producing countries. Given the scope

for cogeneration at petrochemical and

other industrial plants, the potential to

develop trigeneration and large district

energy systems for buildings, campuses

and towns, opportunities in the Middle East

for the cogeneration and on-site power

industry must be growing. That’s more than

can be said at the moment about many

other regions.

Lighting up the dark contınent with decentralized energy

Over the years Africa has become

known as the dark continent,

largely because of the mystery

surrounding this vast land

mass. However, if one were to fy across the

continent at night, the image is dramatically

different than that of a developed area as

the continent is awash in darkness due to

the absence of electricity and lighting. Just

as Africa has begun to bridge the ‘digital

divide’ through use of wireless communication

technologies, it may soon be able to power up

through smaller-scale decentralized energy

projects that do not require miles and miles of

poles and wires.

Last June, US president Barack Obama

announced his ‘Power Africa’ initiative with

the goal to double access to power in sub-

Saharan Africa. More than two-thirds of the

population of sub-Saharan Africa is without

electricity, and more than 85% of those living

in rural areas lack access. According to the

White House, Power Africa will build on Africa’s

enormous power potential, including new

discoveries of vast reserves of oil and gas, and

the potential to develop clean geothermal,

hydropower, wind and solar energy. It will help

countries develop newly-discovered resources

responsibly, build out power generation

and transmission, and expand the reach of

mini-grid and off-grid solutions.

Having recently returned from a meeting

of the Africa Gas Association, it is apparent

that the dash to gas is not confned to North

America, but is spreading rapidly throughout

Africa, including the eastern regions. As this

natural gas production advances it will create

localised opportunities for power generation

that is clean, affordable and effcient. While

some of this new natural gas production may

be destined for export markets, as a localised

gas distribution network develops it will allow

for new uses and markets to progress as well.

WADE is excited about the prospect for

decentralized power in Africa and about

the potential for the coupling of natural

gas with power generation technology to

create economic opportunities, a cleaner

environment, improved access to healthcare,

expanded educational experiences, and an

overall improvement in the quality of life.

To this end, WADE is planning to follow up

the meeting with the Africa Gas Association

with a meeting in Cape Town on 19 March

in conjunction with POWER-GEN Africa

(www.powergenafrica.com). The potential

is as large as the continent and WADE

hopes to be a fundamental player in Africa’s

decentralized energy future. We hope to see

you in Cape Town or elsewhere under the

shining lights that will illuminate the previously

‘dark continent’.

REPORT BODES WELL FOR COMBINED HEAT AND POWER

Combined heat and power

and carbon capture and

storage technologies will help

push the generation of the

global thermal power market

to 19,869.1 TWh by 2020,

according to new data.

A report from research and

consulting frm GlobalData

states that the past few

years have seen “heavier

investment into research and

development to improve

fossil fuel technologies that

can generate power at a

higher capacity factor, whilst

displaying a minimal impact

on the environment”.

It adds that the fact that

energy effciency and security

now form the foundations

of many countries’ power

policies is also a major

contributing factor behind

these investments.

“CCS has been deemed

one of the most effcient

technologies for reducing

carbon dioxide emissions while

maintaining the use of fossil

fuels for electricity generation,”

says the report. “Similarly, CHP

provides an effcient and

clean approach to generating

electricity, and useful thermal

energy, from one fuel.”

Sayani Roy, GlobalData’s

power analyst, said: “These

two technologies are in high

demand among countries

where electricity is mainly

generated from thermal

resources, and the governments

of major economies have been

focusing substantially on the

mandatory adoption of such

technologies to help reduce

emissions from their respective

power sectors.”

She highlighted the situation

in the US, where the government

has rolled out various acts

and policies which make the

adoption of CCS and CHP

technologies obligatory, while

also supporting power facilities

fnancially in adopting it.

She added that countries

such as India, China, the

UK and Germany have also

been taking signifcant steps

towards the adoption of these

technologies in order to reduce

local emissions.

Japan’s new power sources – to include CHP?It’s not often that the

decentralized energy spotlight

shines on Japan. Yet, with the

‘fallout’ from 2011’s earthquake,

tsunami and destruction of

the Fukushima Daiichi nuclear

power plant still in the air, there

is much interest in how the

country will realign its energy

and electricity policies.

The greater use of gas to

generate power in thermal

plants has been the short-

term answer, with the

resulting increased imports of

expensive natural gas. Could

cogeneration also beneft?

CHP’s current status is

healthy. Japan has nearly

10 GWe of CHP generating

capacity in place, four-ffths of

this in the industrial sector and

the rest serving commercial

buildings and, through

micro-CHP technology, homes.

After strong capacity growth

in the 1990s and until 2008,

growth then almost halted

until last year, when 400 MW of

new plants were added.

All this according to a

new report on the status of

and prospects for CHP and

district heating and cooling

(DHC): Country Scorecard:

Japan, published under the

International Energy Agency’s

CHP/DHC ‘Collaborative’.

CHP’s prospects are less

certain – it’s hard to say

whether the growth in capacity

in 2012 represents the start of

a new, post-Fukushima upward

trend. But there is considerable

room for optimism, says the

IEA. It suggests that the market

for CHP may develop around

three main opportunities:

possible new policy incentives

for CHP following the tsunami;

continued support from the

government and Japan’s gas

industry for micro-CHP; and a

growing role for fexible CHP

systems to work within smart

energy networks.

AL GORE’S NEW

HQ POWERED BY

FUEL CELL CHP

Former US vice president Al

Gore’s new London, England

headquarters is to be powered

by fuel cell combined heat

and power technology.

The fuel cell has already

been installed at the Crown

Estate development on

Regent Street in central

London, where Generation

Investment Management, Mr

Gore’s sustainable investment

company, is sited.

The cost of the new system,

the frst of its kind to be

installed in the UK, has not

been revealed.

The cell was developed by

US company FuelCell Energy

and will emit 38 per cent less

carbon dioxide than using

electricity from the grid and

heat from gas-fred boilers,

according to the Crown Estate,

which says 350 tonnes of

carbon dioxide emissions will

be saved per year.

The new plant forms

part of the central energy

system which serves

46,452 m2 of offces, shops, fats,

restaurants and hotels in the

Quadrant development.

TRANSCANADA COGENERATION PLANT GETS GE BOOST

TransCanada’s Mackay River industrial

cogeneration facility in Alberta has increased

its output capacity by 10 per cent and boosted

its fuel effciency by more than 2 percent after

hardware and software upgrades from GE.

Commissioned in 2004, the plant features

a combustion turbine generator and heat

recovery steam generator which produce

165 MW along with 720 tonnes of steam per

hour. The plant supplies power to PetroCanada’s

Mackay River enchanced oil recovery (EOR)

bitumen extraction facility.

GE’s upgrades were installed on one natural

gas-fred combustion turbine at the plant,

reducing emissions by around 1600 tonnes of

NOx per year. TransCanada now expects three

additional power generating days per year

for the plant, which operates nearly 24 hours

per day. The company also expects reduced

maintenance outages.

Because the bitumen extraction facility uses

large quantities of steam, the plant includes

one of the world’s largest EOR heat recovery

steam generators.

Ikea installs rooftop solar in Spain

Swedish furniture retailer Ikea

continues its drive to power its

stores with on-site renewables

with a new rooftop solar

installation in Spain.

The 480 solar panels on the

roof of Ikea’s store in Sabadell,

Barcelona produce around

158,000 kWh per year, which

the store consumes on-site.

Ikea has installed rooftop

solar on fve of its Spanish stores

this year, using solar panels

from REC, the largest European

solar panel supplier. REC says

its Spanish installations for Ikea

generate around 12,000 kWh

per year.

The new solar installations

are part of the “Ikea

renewable” project, launched

in 2007 and designed to

ensure that each Ikea store

generates enough power from

renewable sources to cover its

own demand. Since its launch,

the project has reduced Ikea’s

power bill by almost €2 million

per year, and achieved energy

savings of 11,795 MWh, the

company says.

Ikea’s latest investment in

on-site solar power comes

at a time when Spain’s solar

market is in disarray following

retroactive feed-in tariff cuts

and a profts cap for renewable

energy producers. ‘Against this

backdrop, projects such as

Ikea’s offer a promising vein

of opportunity to the solar

industry,’ REC said.

SWEDISH DISTRICT HEATING PLANT ORDERS FLUE GAS CONDENSER

Falkenberg district heating

plant in Sweden has ordered

an SRE fue gas condenser.

The plant, which is run on

biomass, will see the installation

of the equipment performed by

Opcon AB.

SRE’s fue gas condenser

effciently captures waste heat

in smokestack gases and

recycles the energy to the

district heating grid. The fue

gas condenser, that adds some

1.7 MW to the system, increases

energy effciency by up to

20-25 per cent depending

on fuel, thereby helping

Falkenberg Energi to reduce

its fuel consumption and lower

emissions considerably.

The condenser will be

installed at the facility’s 8 MW

boiler in Falkenberg. Order

value amounts to around

US$780,000 and the delivery

is expected at the beginning

of 2014.

Valve Control Management. Go from idling to full

load twice as fast.

What to know what it takes? Valve Control Management (VCM®) is intelligent

turbo charging that responds adaptively to change valve timing so that your engine

always has the ideal air-to-fuel ratio. And since VCM increases engine efficiency

by optimizing engine configuration for every type of load, it can take an engine from

idling to full load twice as fast as it normally takes – in some cases even more

quickly. The resulting lower thermal load and exhaust gas temperature will also make

your equipment more reliable and durable and reduce pollution at the same time.

Fuel Cell CHP Plant Delivered to

German Ministry

Fuel cell power plant provider

FuelCell Energy Solutions

(FCES) has announced

delivery of a combined

heat and power plant to

the German education and

research ministry’s Berlin offce

complex, which is currently

under construction.

FCES will install the power

plant inside the offce

complex and commissioning

is expected in mid-2014.

Generating 250 kW, the

plant will supply 40 per cent of

the offce building’s electricity

needs and 20 per cent of its

thermal needs. Heat from the

plant will be used to generate

steam for facility heating and

absorption chilling.

The company says its

technology is fuel-neutral

and can use natural gas,

renewable biogas, directed

biogas and other fuels such

as propane. The Berlin power

plant will be fueled with

natural gas.

Founded in 2012, FCES is

a joint venture of Fraunhofer

IKTS and US-based FuelCell

Energy Inc. It is headquartered

in Dresden and has opened

a manufacturing facility

in Ottobrun.

LATIN AMERICAN BREAKTHROUGH

FOR BIOMASS APPLICATION

The San Juan de Olivos

olive facility in Argentina is

expecting to make signifcant

savings from the installation of

a biomass gen-set.

Dresser-Rand installed the

frst Guascor gen-set for a

biomass application in Latin

America at the San Juan

olive harvesting and olive oil

production facility.

The technology will power

the plant’s operation as well

as potentially provide surplus

power for the San Juan area

and is forecast to save the frm

up to US$600,000 in electricity

costs every year.

Dresser-Rand worked on the

project with LatAm Bioenergy

Group, a New York-based

engineering, procurement

and construction company,

focused on the sustainable

development of renewable

energy solutions in Latin

American countries.

The ‘green’ power project

will use a Guascor SFGLD360

containerized CHP unit to

gasify the facility’s biomass to

produce syngas. The syngas

will power San Juan de Olivos’s

production facility. The biomass

employed in this project will

be the waste wood collected

by pruning the olive trees,

and the extracted olive mash

and pits discarded during oil

production.

The process is expected

to yield roughly 250-300 kWe

each day – covering all of the

facility’s energy demands. San

Juan de Los Olivos is also in the

process of acquiring a license

that will allow the facility to

generate surplus electricity that

can be exported to the Energía

San Juan power grid.

KIEV RESIDENTS FACING CHILL

Half the residents of Kiev,

Ukraine are in danger of being

left without heat as winter

approaches after the city’s

electricity operator ordered gas

pressure to be cut to combined

heat and power plants.

Interfax Ukraine reports that

over 7000 Kiev heat consumers

(including houses and social

sphere facilities) could be left

without heating and hot water

supplies in the coming frst

autumn frosts after Kyivtransgaz

cut gas pressure to combined

heat and power plant fve and

combined heat and power

plant six.

The gas pressure is reported

to have been reduced as

Kyivenergo owed US$256m

(UAH 2.1 billion) to Naftogaz

Ukrainy for gas consumed. The

action has been a frequent

occurrence in the winter

months for the city.

At the moment Kyivenergo

supplies heat to only 17.6% of

residential buildings, 93% of

kindergartens, 48% of schools

and 82% of hospitals, as a result

of the action.

FORTUM SELLS

KUUSAMO

PLANT AS PART

OF EFFICIENCY

STRATEGY

Fortum has sold its cogeneration

plant at Kuusamo, Finland

to district heating specialist

Adven Oy for an undisclosed

price, as the company

seeks to drive through its

effciency programme.

The programme, which

began a year ago, sees Fortum

concentrating its combined

heat and power production to

larger centres and units.

The production capacity

of the Kuusamo plant is 6 MW

electricity and 19 MW district

heat. The Kuusamo energy and

water cooperative has been

responsible for operating the

Fortum-owned plant.

ALSTOM WINS

CHP CONTRACTS

Alstom has won US$231 million

worth of contracts to service

power plants in North America,

two of which are cogeneration

power plants.

The two CHP contracts are

located in Ontario and Alberta,

Canada, respectively.

Alstom was chosen to

execute a LTSA contract

with TransAlta Corp. (TAC)

in Canada for their Sarnia

cogeneration power plant

in Ontario and Poplar Creek

Cogeneration power plant

in Alberta.

Both TransAlta plants

operate Alstom built GT11N2

gas turbines.

The parts agreement will

be progressively booked

throughout the execution of

the contract.

On-site power delivers a jolt to US utilities

Which companies generate the most

power from on-site renewable resources

in the US? In absolute terms, some very

large entities indeed – Wal-Mart Stores,

the US Department of Energy, Apple,

BMW Manufacturing and Coca-Cola

Refreshments – take the frst fve places

in a league table drawn up by the US

Environmental Protection Agency from

companies within its Green Power

Partnership. Wal-Mart stores generate

more than 100 GWh per year from biogas,

solar and wind power installations, while

Coca-Cola generates nearly half of

that, from biogas-to-power plants. But

Wal-Mart’s on-site generation represents

just 1% of its total power needs; Coca-

Cola generates just 6%.

Higher proportions of total power

use are to be found further down the

table. In fourteenth place lies the mainly

agricultural County of Yolo, in Northern

California, which generates 1.5 times

its own electricity requirements from

a series of solar power plants totalling

7 MW of capacity. And, in 19th place, the

Encina Wastewater Authority in Southern

California generates more than two thirds

of its electricity requirements from its own

waste biogases.

The EPA has recently honoured Apple;

the County of Santa Clara in California;

health care provider Kaiser Permanente

and the Chattanooga, Tennessee car

assembly plant operated by Volkswagen

Group of America for their use of

on-site power generation. Apple uses

a combination of large solar PV arrays

and biogas-to-power plants to supply

16% of the electricity requirements of its

US data centres and other facilities. The

County of Santa Clara, Kaiser Permanente

and Volkswagen Chattanooga all rely

on PV to supply towards 10% of their

electricity needs.

The EPA list ignores those public and

private sector organisations that use

gas-fred on-site CHP schemes, preferring

to highlight the role played by on-site

renewables. Put both of these generation

sources together, though, and a picture

emerges of US businesses staring to see the

sense of on-site energy generation as a way

to cut energy costs and insulate against

supply interruptions.

Separate from the EPA Green Power

Partnership, a recent Wall Street Journal

report describes on-site wind and biogas

schemes for a dairy in Pennsylvania and

a food distribution centre in California.

Meanwhile, home furnishings retailer

Ikea plans to incorporate geothermal

technology into the heating and

cooling systems of the store it is building

outside Kansas City. The company says

it either owns or operates more than

130 wind turbines and has installed

more than 30,000 solar panels for its

European operations.

English cogen specialist recognised for industry leadershipENER-G has been recognised

as a global leader in combined

heat and power technology,

after being shortlisted for the

Manufacturer and Engineer of

the Year Award in the Insider

North West International

Trade Awards, which will be

announced in December.

The nominations,

which recognise business

achievement in the northwest

of England, comes after the

company’s success in the

prestigious COGEN Europe

20th anniversary awards for

exceptional contribution to the

European CHP sector.

ENER-G was the only

UK company recognised,

receiving the Market

Development Award for

its international role in

the advancement of

cogeneration.

The company designs,

manufactures, installs, fnances

and maintains cogeneration

systems from small-scale

4 kWe to large industrial

10 MWe modular installations –

fuelled by natural gas, biogas,

propane, biodiesel or pure

plant oil (PPO).

A European market leader

in CHP, the company has

30 million hours of

cogeneration operating

experience and 695 MW of

generation capacity, which

has offset 1.5 million tonnes of

CO2 per year.

Major clients include

GlaxoSmithKline and

David Lloyd Leisure and

the company has worked

throughout Europe and most

recently begun implementing

projects in the US.

ENER-G pioneered the

pay-as-you-save Discount

Energy Purchase scheme in

the 1990s. This gives cash-

strapped organisations

access to CHP technology

and associated energy

effcient solutions, without any

up-front investment.

EIB PROMOTES USE OF CHP IN RUSSIA

The Primorye region on the east

coast of Russia is to beneft

from a European Investment

Bank (EIB) loan, which is set to

improve its energy capacity.

EIB is lending US$135 billion

(RUB 4 billion) to support the

modernisation of power and

heat generation technology

in Vladivostok, the regional

capital. It will enable electricity

to be generated to facilitated

50,000 apartments and heat

more than 600 family homes.

The project is part of a

larger programme to bring

natural gas to Russia’s Far East,

enabling a switch from coal

to natural gas as the primary

energy source and reducing

CO2 emissions.

The loan – the frst ever to be

extended by the EIB in Russian

roubles – will fnance the

installation of three new state-

of-the-art combined heat and

power gas turbine units, which

will increase electricity and

heat production and bring

environmental and energy

effciency performance

into line with best practice.

‘This loan will contribute

to climate change

mitigation, which is a key

priority for the European

Union and therefore also

one of the key operational

priorities of the EIB,’ said

Wilhelm Molterer, EIB vice

president responsible

for lending operations in

Russia, adding that the

project also contributes

to the implementation of

the EU–Russia Partnership

for Modernisation.

The operation is being

carried out under the EIB’s

Climate Change Mandate for

non-EU countries introduced

in 2011 and is being

co-fnanced with the European

Bank for Reconstruction

and Development.

Each of the three new

units will consist of a 46.5 MW

high-effciency gas turbine

and an associated 40 Gcal/h

heat-recovery hot water

generator. This will help to cover

the heat base-load throughout

the year in Vladivostok and

supply electricity to the region.

The project also includes

the installation of three

heat-only boilers (100 Gcal/h

each) to cover winter/peak

loads and replace the old

heat-only boilers currently

being used.

VASKILUODON VOIMA CHP PLANT IN LINE FOR METSO RETROFIT

Finnish power producer

Vaskiluodon Voima has agreed

with Metso on an extensive

automation retroft for a

combined heat and power

plant in Seinäjoki, Finland,

replacing the automation

system the plant has used

since 1989.

Metso will install its DNA

automation system as well as

new automation for the fuel

reception, water plant, auxiliary

boiler and ash handling. It will

also provide an update to the

reporting system, an emission

monitoring application in line

with Europe’s 2010 Industrial

Emission Directive, and new

combustion control methods.

Metso expects to complete

the work by August 2014.

The Seinäjoki power plant

supplies local electricity and

district heat with a boiler

capacity (steam capacity)

of 299 MW, turbine electrical

capacity of 125 MW and district

heat capacity of 100 MW.

The plant’s primary fuels are

wood chips and peat, with

coal used as a backup fuel.

UNIVERSITY OF CALIFORNIA

COGENERATION PLANT GETS ITS

POWER BACK

Power has been restored to

the University of California at

Berkeley’s cogeneration plant,

which had been without power

since an explosion damaged

the campus’s underground

power lines on 30 September.

The university’s public affairs

offce said an investigation will

be launched into the cause of

the explosion.

The cogeneration plant

uses a natural gas-fred GE

LM2500 turbine generator to

produce 25 MW of electrical

power and 4 MWth of steam,

which is distributed through

underground tunnels to heat

campus buildings. The plant

is operated by GE and has

been online since 1987, with an

upgrade in 1998.

On-site power and heat

are common on the University

of California’s 10 campuses

-- such as UC Irvine’s 18 MW

cogeneration plant which uses

a combustion turbine and heat

recovery steam generator with

a chiller addition. And UC San

Diego’s combined heat and

power facility, which features

two 13.5 MW gas turbine

generators, is part of a campus

smart microgrid system that

incorporates photovoltaic

solar panels and fuel cells and

meets over 90 percent of the

campus’s power needs.

E.ON to supply CHP for Russian

industrial parksE.ON and DEGA Group, a real estate developer in the Russian

Federation, have entered into a long-term partnership agreement

to build and operate on-site power generation facilities for DEGA’s

Russian industrial parks.

DEGA already supplies business tenants on its Industrial Park

Noginsk, 48 km east of Moscow, with electricity and heat from

two 15 MW gas turbine combined heat and power units. E.ON

will now acquire a majority of the DEGA subsidiary that owns

and operates these CHP units, and will have exclusive access to

DEGA’s pipeline of Russian industrial parks.

E.ON says it is expanding its distributed energy activities in

Russia, with a focus on services and light industries. The DEGA

partnership was signed with E.ON Connecting Energies, a new

international unit of E.ON SE focusing on energy effciency and

on-site generation solutions for businesses and the public sector.

Hydrogen as a

cogeneration fuel

has yet to develop

the market

acceptance enjoyed by

natural gas and diesel-

fueled applications. But

that may be changing as

new technologies allow

renewable energy resources

to convert their output into

safe hydrogen that can

be stored for use in CHP

applications. Moreover,

new engine technologies

for generating heat and

electricity from hydrogen

could accelerate the

adoption of hydrogen-

fueled CHP.

In the past, hydrogen-fueled

cogeneration has typically

been associated with fuel

cell technology, and the

high cost of these systems

has been a limiting factor for

hydrogen’s viability as a fuel for

stationary power applications.

But the recent launch of a

dedicated hydrogen-fueled

CHP cogeneration system

from 2G Cenergy could

be a turning point for a

more economical solution,

according to Michael Turwitt,

the company’s president and

CEO, based in St. Augustine,

Florida, US.

“The idea to utilise fuel cells

for power generation sounds

very attractive for clean and

effcient energy production,”

says Turwitt.

“However, there are still

issues associated with the

technology such as very

high manufacturing costs,

performance and durability

issues, and high cost of fuel

production, especially if a

reformer is applied,” he says.

“Also, fuel cells require very

pure fuel, free of contaminants

including sulphur and other

carbon compounds. None

of these contaminants

inhibit combustion in an

internal combustion engine,

and reciprocating engines

do have a much higher

Hydrogen-fueledCHP now on the horizon

Hydrogen as a fuel for cogeneration has yet to develop the market acceptance enjoyed by natural gas and

diesel-fueled applications, but new engine technologies for generating heat and electricity from hydrogen

could accelerate the adoption of hydrogen-fueled CHP, writes Ed Ritchie.

Innovations promise hydrogen-fueled cogeneration

The installation of 2G’s hydrogen fueled, engine-based CHP systems at the new Berlin Brandenburg Willy Brandt Airport energy station marks an important milestone

tolerance level for such

fuel impurities.”

According to the National

Fuel Cell Research Center at

the University of California,

fuel cells could become

competitive with traditional

engine technologies in the

stationary power market if

they reach an installed cost

of US$1500 or less per kW.

(Currently, the cost is in the

range of $4000+ per kW.)

Compared to prices of $800

to $1500 for reciprocating

engine-based CHP systems,

Turwitt expects to see a broad

range of applications for

2G Cenergy’s products. For

example, the frst units found

a home at an energy station

within the Berlin Brandenburg

Willy Brandt airport in Germany.

The CHP installation

uses two hydrogen-fueled

engines powering 2G’s

Agenitor CHP systems, with

an output currently set at

400 kW/unit (units are capable

of 500 kW output). The CHP

plant functions as part of

a larger hydrogen vehicle

fueling project, operated by

a multi-national oil and gas

consortium that includes

Total (oil and gas distributor

and commercial flling

station operator), Enertrag

(renewable energy and wind

turbine project operator) and

The Linde Group (industrial

gas supplier and hydrogen

plant operator).

Given the commercial

partners and the German

government’s strong support

for hydrogen as a clean energy

fuel, the timing could not have

been better to introduce a

hydrogen-fueled reciprocating

engine at the Berlin airport,

because the CHP system

expands the existing hydrogen

vehicle fueling station into

a self-contained hydrogen

complex. By incorporating an

Enertrag wind farm plus solar

panels from a Total subsidiary,

the project could achieve

100% renewable electricity to

power the system, supporting

an electrolyzer that produces

about 200 kg of hydrogen per

day (equivalent to about 50

full tanks of fuel cell cars).

Linde is responsible for the

development, installation

and technical operation of

the hydrogen station, which

plays an important role in

the conversion of wind to

hydrogen as a method for

gaining maximum effciency

from wind turbine generation

when there is no demand for

its output.

A portion of the hydrogen

now fuels 2G Cenergy’s CHP

system, generating green

energy for heat and electricity

at the airport where safe

operations at the plant are

critical to the project’s success,

according to Turwitt. “Using

hydrogen has always been a

safety question,” he says

“A lot of people have

said that hydrogen is highly

explosive and needs to be

handled safely, and that

requires certain technologies.

There are car manufacturers

that have hydrogen engines

in their vehicles but it’s never

been done as a serious

product for prime power

generation and CHP.

“I think the biggest

breakthrough is our fuel

injection technology. Our

engineering group has

been working on this for

quite some time and it

helps tremendously for safe

operations. The port injection

enables us to prepare

and mix the fuel before it’s

injected into the combustion

chamber. That makes it

extremely safe and very

economical.”

It is worth noting that

the CHP plant’s hydrogen

gas storage system

also represents a major

breakthrough for the industry.

Typically, hydrogen fuel

produced by electrolysis can

fuctuate, but this problem

is solved by a technology

for storing hydrogen in solid

form (metal hydrides) at

low pressure. This storage

enables a permanent supply

of hydrogen fuel for the 2G

CHP system.

It is manufactured by McPhy

Energy, based in Grenoble,

France, and uses a magnesium

hydride solid storage

technology. The airport unit

holds up to 100 kg of hydrogen

produced from electrolysis.

Safe storage is a key beneft,

and the technology can store,

at atmospheric pressure, as

much hydrogen as a 500

bar storage within the same

volume.

Utility-scale energy storage

is a high priority in Germany’s

clean energy strategy. The city

of Berlin has offered €200 million

($271 million) between 2011

and 2014 for energy storage-

related research.

For the airport project,

the fnancial commitment

is equally impressive. The

funding for the capital and

operating costs (maintenance

and repair) to mid-2016

alone amounts to about

€10 million. Among the

commercial partners, Linde

and Total each invested over

€3 million. For Enertrag, it is

€2 million and for the CHP

system, 2G has committed

€1 million.

On the federal side,

the National Innovation

Programme for Hydrogen and

Fuel Cell Technology (NIP)

is providing 50% funding to

the participants to support

the federal government’s fuel

strategy. According to Enertrag,

the investment is justifed. The

company’s research shows

that Germany’s storage

facilities amount to roughly

2G’s IL6 and V12 hydrogen-fueled engines power its agenitor® 306 and 312 CHP systems

Innovations promise hydrogen-fueled cogeneration

0.07 TWh, but the country’s

requirements for 2050 will

exceed 40 TWh.

Siemens is planning to fll

some of that storage gap. The

German engineering giant

is designing a large-scale

electrolysis system to convert

wind energy into storable

hydrogen, with a pilot project

to begin in 2015.

Germany has another

important wind-to-hydrogen

project, though in this case,

rather than storing the

hydrogen on site, it is fed

directly to the natural gas grid.

The new power-to-gas system

was built by Canada-based

Hydrogenics for German utility

E.ON, and its key advantage

is its high storage capacity

within natural gas pipelines.

Globally, energy storage

is on the rise. According to

Navigant Research, in the frst

six months of 2013, 38 new

advanced energy storage

projects were announced,

deployed or started, which

brings the worldwide total

to 633 projects operating or

under development. Most

signifcant hydrogen storage

projects that are making

progress have some form of

government funding.

For example, in France,

the Areva Group is supplying

an industrial energy storage

system, developed with the

backing of OSEO, the French

public body for the funding

and support of technological

innovation, as part of the

Horizon Hydrogen Energy

(H2E) programme. Areva’s

Greenergy Box combines

an electrolyzer to make

hydrogen and a fuel cell to

generate electricity.

In Japan, the Ministry of

Economy, Trade and Industry

has a project in Kitakyushu City

that uses a 100 kW solar panel

array and 60 kW wind turbine

to make and store hydrogen

for a 400 kW fuel cell.

Through Scottish Enterprise,

Scotland’s government has

contributed £2.8 million

($4.5 million) towards the cost

of the Hydrogen Offce building.

The project includes a 30 kW

hydrogen production system, a

750 kW wind turbine, hydrogen

storage, and a 10 kW hydrogen

fuel cell.

In the US, progress on

wind-to-hydrogen has been

limited to just a few projects. The

National Renewable Energy

Laboratory (NREL), a division

of the Department of Energy

(DOE), partnered with Xcel

Energy on a demonstration

project at the National

Wind Technology Center in

Boulder, Colorado.

From December 2008

through September 2009,

NREL operated a Mercedes

Benz F-Cell fuel cell vehicle

with hydrogen from wind and

solar PV, but the pilot has run

its course. More recently, a

$4.6 million DOE grant secured

by the town of Hempstead.

Long Island, funded a single

wind turbine to power a

water-to-hydrogen process,

with the ultimate goal of

fueling the city’s hydrogen

vehicles and a bus.

Overall, the opportunity for

hydrogen storage projects in

the US is growing. Renewable

energy accounted for nearly

50% of all new US electric

generation in 2012, according

to Ernst & Young, while 13.1

GW of wind was added to its

grid last year, and total wind

installations reached 60 GW of

installed capacity.

There is at least one US

utility-scale wind-to-energy

project on the horizon.

Norfolk Wind Energy, National

Renewable Solutions and

Millennium Reign Energy

recently announced plans for

a 10 MW wind-to-hydrogen

facility in Renville County,

Minnesota. The project

will produce 500,000 kg of

Hydrogen production research: from soybeans to siliconAs the market for hydrogen continues to grow, research projects focused on reducing production costs are on the rise. Much of the focus is on fnding alternatives to the use of palladium and platinum to catalyze the chemical reaction in processing hydrogen. Such heavy metals are expensive, non-renewable and toxic.

The technologies being studied have a surprisingly diverse range of approaches. For example, at the US Department of Energy’s Brookhaven National Laboratory, researchers have identifed soybean derivatives and molybdenum metal as low-cost replacement candidates.

Nanotechnology is another approach to reducing catalyst costs. Researchers at Japan’s Institute of Physical and Chemical Research and Institute for Molecular Science have partnered with McGill University in Canada to study iron nanoparticles as an alternative catalyst material. Iron is also the material of choice for researchers at the US Pacifc Northwest National Laboratory.

At the University of Buffalo, researchers are testing nanotechnology for creating spherical silicon particles that react with water to create hydrogen.

Meanwhile in France, scientists at the Collège de France, CNRS and Université Joseph Fourier in Grenoble are studying hydrogenase, which is found in microorganisms that use hydrogen as a source of energy.

The results offer a wide variety of hydrogenase enzymes found in nature, and the possibility of enzymes that may potentially serve as catalysts for fuel cells or the production of hydrogen from sources of renewable energy.

Scientists at the UK’s University of Cambridge have developed a process using water with a low-cost catalyst (cobalt), surrounded by atmospheric oxygen, for processing hydrogen at room temperature.

Moving from room temperature to blistering heat, a University of Colorado team has designed a concentrated solar mirror and tower system to create hydrogen. The mirrors focus sunlight on a 61-metre tower and heat it to 1350°C. The heat is used in a reactor that houses steam and metal oxides to create hydrogen.

Finally, in Germany, The Linde Group is extracting hydrogen from raw glycerol, a byproduct of biodiesel manufacturing.

Innovations promise hydrogen-fueled cogeneration

hydrogen annually, and the

partners are exploring the

option of using a hydrogen-

fueled 1 MW fuel cell to

sell electricity to a local

grid operator during peak

demand hours.

Projects worldwide refect

a positive environment for

hydrogen as a fuel and energy

storage resource, says Henning

Tomforde, head of Market

Development, Hydrogen

Solutions and Marketing,

Clean Energy at Munich-

based The Linde Group.

“A lot of demonstration

projects are planned or

ongoing for both cogeneration

and hydrogen-powered feet

operations such as cars, buses

and forklifts. Slowly but surely

we are seeing various markets

around the globe evolving.”

As with Berlin’s airport

project, much of the focus

is on hydrogen production

from renewables, storage

and transport, but Tomforde

notes that the growth of the

hydrogen for vehicles market

can have a positive effect

on storage and stationary

power generation.

“In general, cogeneration

and hydrogen fuel

infrastructure for cars are not

necessarily linked, but I’m quite

sure that it will have a positive

effect due to the fact that the

infrastructure in general is

getting more widely available,”

he says. “Also the acceptance

and awareness of hydrogen is

getting better.”

In April 2013 The Linde

Group promoted hydrogen

at the Hannover Messe trade

show, showcasing its latest

developments in stationary

fueling technologies. In the

past two years alone, Linde

developed and built more than

10 hydrogen stations, three of

which generate hydrogen on

site from renewables.

One of the recent projects

opened in March 2013, for the

utility EnBW Energie Baden-

Wurttemberg AG, as part of

the Clean Energy Partnership

(CEP) in Stuttgart, Germany.

Another source of

awareness for hydrogen comes

from its steady growth and

distribution in conventional

industrial markets.

“Even if they focus on

industrial applications, the

more hydrogen clusters

the better it is for any

alternative, new hydrogen

applications such as use as

a fuel for transportation or

cogeneration,” says Tomforde.

“The overall infrastructure

for hydrogen is getting denser,

and usually when something

becomes denser and more

widely available it is more

economically viable.”

Ultimately, economic

viability is the bottom line for

hydrogen-fueled CHP, and the

Berlin airport project looks to be

an ideal test site for evaluating

two key issues – the use of

renewable energy resources

for hydrogen production and

the viability of hydrogen-fueled

CHP applications.

Until now, hydrogen and

CHP have been dominated

by fuel cell applications that

are rarely undertaken without

some form of government

funding. But reciprocating

hydrogen-fueled engines

that can offer an economic

proposition comparable to

natural gas and diesel could

establish hydrogen-fueled

CHP as a viable alternative.

Coal to CHP conversion

The US state of

Michigan is best

known as home

to Detroit, an auto

manufacturing giant now

infamous for its economic

decline. While Detroit’s

problems get much of

the attention, Michigan’s

capital city, Lansing, has

been quietly prospering and

paints a far different picture

of the state.

Lansing grew tremendously

in the last century with the rise

of the auto industry. But today

the city prospers through a

diversifed economy. General

Motors still operates in Lansing,

but ranks a distant fourth as

a jobs producer. Government,

education and healthcare are

the largest employers among

the city’s 115,000 inhabitants.

Lansing has the advantage

of serving as both the seat

of the state government

and home to Michigan

State University. The city has

two medical schools, one

veterinary school, two nursing

schools, two law schools, the

state Supreme Court and

Court of Appeals, a federal

court, and headquarters

of four national insurance

companies. In 2011, Forbes

Magazine ranked Lansing as

19th for job growth among

When it came time to build Michigan’s frst new utility power plant in 25 years, the Lansing

Board of Water and Light chose combined heat and power. The new 100-MW plant began

operating in July. Elisa Wood explores how and why Michigan’s state capital came to

choose CHP to replace an aging coal-fred generating plant and coal boiler.

mid-sized cities, jumping 49

spots from its 2010 scoring.

The city receives such praise

in part because of its urban

revitalisation programme

started more than a decade

ago. Against the backdrop of

this renewal, the Lansing Board

of Water and Light (BWL) –

Michigan’s largest municipal

utility – decided to replace its

50-year-old coal-fred power

plant and a separate coal

boiler with a state-of-the-art,

natural gas-fred combined

heat and power facility.

Called the REO Town

Headquarters and

Cogeneration Plant, the

100 MW combined-cycle

project went into commercial

operation in July to help serve

the municipal utility’s 151,000

customers (96,000 electric,

55,000 water and about 225

steam/chilled water) who

consumed 2.9 million MWh

in 2012.

The project’s beginnings go

back more than half a dozen

years, when BWL realised it

would need to replace the

coal-fred power plant known

as the Eckert generating

station. The utility furthered

the idea in its 2008 Integrated

Resource Plan, where it noted

that cities of the future need

inexpensive energy supply

and plenty of it. Major data

centres, the report noted, can

consume as much electricity

as an automobile assembly

plant. It was not that Lansing

was expecting any large

increase in its electric demand,

certainly nothing like the 5-10%

annual rate the city saw during

its manufacturing boom of

the 1940s–50s. In fact, like

much of the US, Lansing was

forecasting modest growth of

about 1.4% annually. But utility

planners saw little future for

the Eckert plant. It was aging

beyond its useful life, and even

its newer units were likely to

require expensive upgrades to

meet evolving environmental

standards. Lansing needed

new power to replace it.

Coal loses favour

At frst, BWL planned to meet

the need with a hybrid

biomass/coal baseload plant,

plus renewable energy and

energy effciency. The utility

reasoned that the hybrid

would protect customers from

fossil fuel price spikes and the

overall strategy would lower

the utility’s emissions profle.

But BWL soon began to

reconsider because of new

rules that the Environmental

Protection Agency (EPA) was

foating for coal-fred boilers.

Of particular concern was the

Maximum Achievable Control

Technology rule for industrial,

commercial and institutional

boilers and process heaters,

known as Boiler MACT. The

rule limits mercury, carbon

monoxide, fne particulates

and other forms of air pollution

from new and existing boilers

of a specifed size. Complying

with the rule carries a hefty

price tag for the 14,000

industrial boilers affected: an

average US$4.4 million per

coal boiler and $1.9 million per

oil boiler for necessary capital

improvement and compliance

measures, according to

the EPA.

Boiler MACT does not

apply to power generation

facilities, so Lansing was not

concerned about its new

power plant. But it was worried

about its neighbouring

Moores Park steam plant. The

coal boiler supplied steam to

heat buildings in downtown

Lansing, including the state

capital building, as well as the

nearby General Motors Grand

River assembly plant. But like

the Eckert generating station,

the steam plant was showing

its age and not measuring

up in a world that demanded

cleaner power. Three of the

Moores Park units were more

than 55 years old, and the

fourth unit more than 40

years old.

BWL could undertake an

expensive retroft or pursue

other options, such as

replacing Moores Park with

new natural gas boilers or

combined heat and power. The

utility announced its decision

in July 2010 – it would move

forward with CHP because of

its effciency, low life-cycle costs

and environmental benefts.

This would allow Lansing to

replace both its generation

and steam facilities with one

new plant.

The utility typically fnances

capital improvements through

internally generated funds.

But given the size of the REO

Town plant, BWL chose to

issue municipal bonds as a

fnancing vehicle. BWL was

able to secure the bonds at

a low borrowing interest rate

because two major rating

agencies – Standard & Poor’s

and Moody’s – issued AA

ratings for the company. This

placed BWL in the top 30% of

rated US public power utilities.

The agencies found that BWL

has strong fnancial metrics

and highly competitive electric

rates, below the state average.

BWL sold $250 million in bonds

in increments of $5000, frst to

Michigan retail investors and

then to institutional investors.

The bonds sold in two days.

With the fnancing in

place, the utility broke ground

on the facility in May 2011.

Construction began soon after

in early summer. The facility

took about 18 months to build

with construction creating

about 1000 local jobs.

The plant uses a steam

turbine and generator that was

manufactured by Elliott Group

in Jeannette, Pennsylvania. REO

Town was built by Lansing’s The

Christman Company, Granger

Construction Company, Clark

Construction Company and

Kramer Management Group,

among others.

A larger revitalisation

While the power plant was

the core of the development

project, BWL sought to

bring other benefts to the

community as well. The project

became part of Lansing’s

larger revitalisation effort.

The new plant is on a 2 ha site

in the REO Town neighborhood.

The location worked for BWL

because it was close to the

utility’s steam and electric

distribution systems. Before

BWL began construction, the

property contained an asphalt

parking lot and the former

Grand Trunk Western Railroad

depot, a building of historical

importance that had suffered

neglect and was closed to

the public. The property once

housed the Diamond Reo

Truck Company, which was

BWL decided to restore the

building’s architecture to again

make it an attractive focal point

of the neighbourhood. But the

utility’s goal was more than

aesthetic; it wanted to help

spur economic development

in REO Town and Lansing and

add to its revitalisation efforts.

The complex makes space

for 180 BWL employees and

the restored Grand Trunk

Western Railroad depot for

meetings of the BWL Board

of Commissioners.

Project achieves frsts

When the $182 million plant

began commercial operation

this July – both on time and on

budget – it was noteworthy for

several reasons. It became the

frst new utility power plant built

in Michigan in 25 years and the

frst new BWL power plant in 40

years. In addition to providing

20% of BWL’s electric genera-

tion, the plant produces up to

136,000 kg of steam for BWL’s

225 steam customers in down-

town Lansing.

BWL sees the plant as a

step toward achieving its

goal of a 20% reduction in

greenhouse gas emissions

by 2020. Compared to the

coal-fred units it replaces,

the new plant offers several

environmental advantages:

• A 50% reduction in

greenhouse gases;

• the elimination of 317,515

tonnes of coal use; and

• a99%drop inmercuryand

sulphur dioxide emissions

and an 85% drop in

nitrogen oxides.

Lansing expects the

facility to bring further kudos

to the city because of its

environmental advantages.

The facility is undergoing

the process to achieve the

prestigious designation of

‘LEED’ – Leadership in Energy

and Environmental Design

through the US Green Building

Council. The headquarters’

green features include solar

panels and a hydrogen

fuel cell.

The project’s green

achievements are in keeping

with BWL’s reputation as an

environmental leader in

Michigan. BWL describes itself

as the frst utility in the state

to establish specifc goals to

acquire renewable energy,

and the frst to offer customers

a group of energy-effciency

incentives. In 2008, the utility

installed the Cedar Street Solar

Array, at the time the largest

solar array in Michigan with

432 photovoltaic panels.

In terms of REO Town’s

operating costs, the market

appears to be working in BWL’s

favour. Natural gas prices have

fallen signifcantly since the

city frst started looking into

replacing its coal facilities.

As a result, fuel costs for REO

at an average of $2.75 per

MMBtu in 2012 and $3.71

per MMBtu in 2013, rising to

an expected $4 per MMBtu

in 2014.

Given the economic,

environmental and aesthetic

improvements brought

by the REO Town project,

the utility is calling the

project transformational.

J Peter Lark, BWL general

manager, said, ‘This state-of-

the-art cogeneration plant

scores a major victory for the

environment. And, we’re proud

that the project has been

called a game changer for

economic development in the

Lansing region.’

But while the project clearly

offers signifcant betterment

for Lansing, will it have a

larger infuence on Michigan’s

CHP industry?

Michigan’s performance

has been somewhat middling

when it comes to CHP. In all,

the state has about 91 CHP

plants that generate more

than 3 GW, according to ICF

International, which keeps a

national database on CHP.

Only a handful of Michigan’s

CHP plants came on line in

the last few years. Several are

vintage, some dating back to

the 1930s.

The state scored reasonably

well, 12th for energy effciency,

on the American Council for

an Energy-Effcient Economy’s

2012 scorecard. But in the

CHP portion of the ranking,

Michigan scored only two

out of a possible fve points,

coming in below par for its

policies on portfolio standards,

incentives, net metering,

emissions treatment and

fnancing.

On the national level, the

Lansing plant arrives at an

important point. President

Barack Obama has set

a target to increase CHP

installations 50% by 2020. This

would increase the nation’s

current CHP stock of about

80 GW by another 40 GW. ICF

has identifed 4.4 GW under

development or construction.

So the US has a long way to go.

With its 100 MW of new

CHP capacity, the REO Town

project may seem like a small

contribution to such a big

goal. But it may go down in

history as one of the early

leaders in a new round of

US CHP development. It is

particularly signifcant that the

BWL project replaced a coal-

fred plant with CHP. Older coal-

fred plants are increasingly

shutting down in the US,

unable to compete in the face

of low natural gas prices and

increasingly stiff air emissions

standards. EIA estimates that

retirements could amount

to anywhere from 19 GW to

45 GW. ACEEE says that some

states could replace 50–100%

of their coal-fred generation

with natural gas-fred CHP.

Will this happen? It’s hard

to say. But with its REO Town

combined heat and power

project, Michigan’s capital city

shows how it can be done.

Innovative waste heat recovery

The (reciprocating)

diesel generator set

market remains fast

growing and vibrant,

representing the fastest

of the distributed generation

technologies available.

Applications including

prime, baseload power

generation (powergen),

backup/standby power and

temporary installations all

continue to see increased

to continue well into the

future, particularly in the

developing world.

A report published by

year states that there remains

steady growth in sales of

reciprocating engines, burning

a range of fuels for powergen

The humble stationary genset is never going to be the sexiest piece of kit, often

criticised as highly-polluting and ineffcient. However, a novel waste heat recovery

technology promises to turn that perception on its head by increasing power,

improving fuel effciency and reducing emissions. Paul Dowman-Tucker explains.

Innovative waste heat recovery

including, diesel, natural gas

and biogas. The latter two fuels

are particularly pertinent in the

context of rising exploration for

shale gas and the increasing

development and exploitation

of renewable gas sources

(such as anaerobic digestion

and landfll gas).

This continued growth

demonstrates that the

economics for reciprocating

gensets work, but in the face

of perennially rising fuel costs

engineers persist in exploring

means to recover some of

the signifcant proportion,

sometimes in excess of

60 per cent, of calorifc value

of the fuel being lost to the

environment as waste heat.

Many technologies have

been explored and developed

to recover some of the waste

energy, predominantly from

the exhaust, but none

of them have yet seen

widespread uptake. Examples

include mechanical turbo-

compounding, steam cycle

solutions, organic Rankine

cycle (ORC) solutions,

thermoelectric materials and

electric turbo-compounding.

The key challenges faced

include cost, the resulting

lengthy payback period,

reliability, and general

development maturity in the

context of a conservative

industry. Additionally, diffculties

associated with space

and weight requirements

also constrain the range

of potential applications,

although perhaps less so in

stationary powergen.

Novel waste heat

recovery technology

Bowman Power Group, based

in the UK, has been working

for the last nine years on

technology to recover waste

heat energy by means of

electric turbo-compounding

(ETC).

Bowman ETC systems have

seen considerable success to

date in stationary powergen

applications working on two

different value models – power

boost (of up to 13 per cent),

or fuel saving (of up to

8.5 per cent).

The technical principles by

which the system operates

are simple on the face of it.

A power turbine stage (gas

expander) is ftted into the

engine exhaust stream, either in

the wastegate fow if available

and appropriate (parallel

application), or downstream

from the engine turbocharger

turbine stage (series

application.) This power turbine

is close coupled to a compact,

high-speed, high-effciency

alternator which produces

high-frequency AC electricity.

This is converted into grid quality

three-phase AC and added

to the host genset output

for connection to the load,

be it a direct load or local or

national grid. This combination

of a turbogenerator and the

matched power electronics

make up the Bowman

ETC system.

In parallel applications, the

presence of the turbogenerator

does not have an impact

on the engine exhaust

aero-thermal characteristics,

and it is therefore simple

to integrate, requiring no

turbocharger modifcations.

In this application model, it is

possible to utilise a proportion,

or all, of the wastegate fow,

depending on requirement,

payback economics, etc,

utilising bypass features and

the control system embedded

within the power electronics.

In the more common series

application, the standard

engine turbocharger is often

replaced or modifed, frstly to

improve its effciency (this gives

some economic benefts in

itself) and secondly to ensure

that, in conjunction with the

turbogenerator, the overall

aero-thermal characteristics

of the engine exhaust system

continue to operate within

acceptable limits.

It should be noted that the

overall system back pressure

is normally increased by

the application of the ETC

system, but in the applications

developed to date this has not

proved to cause a problem

with engine durability, and in

fact a recent study into the ETC

system by Ricardo Consulting

Engineers has shown that there

can even be benefts from the

additional back pressure in

cases where the host genset

engine is ftted with an exhaust

gas recirculation (EGR) system

to help manage emissions.

Ricardo’s overall conclusions

were: ‘The Bowman Power

turbogenerator system clearly

demonstrates the potential for

signifcant fuel consumption

improvements across all the

engine categories assessed

(0.5–2 MW), Furthermore, as

the turbogenerator system

is focused on continuous

rating applications, the

risk of increased exhaust

temperature and pressure

should be minimal.’

Rigorous testing applied

The turbogenerator (TG), power

electronics and sometimes

also the turbochargers are

designed, manufactured

and tested at Bowman’s UK

premises. The design of the TG

has been developed over time

by the experienced and expert

engineering team within

the company and, for some

aspects, in conjunction with

independent consultants. The

turbine itself is highly effcient

and uses fxed nozzle guide

vanes, which can be changed

to optimise the match of the

TG to each application.

The power electronics are

also developed in-house and

deliver an overall electrical

conversion effciency of

approximately 98 per cent,

ensuring the maximum

possible beneft to the end

user. The power electronics

are modular in concept,

centred on a standard

converter module that can

be confgured for the different

functions in the power

electronics and grouped

together in various numbers

to provide the overall capacity

necessary for the application

at hand. In the face of

developing grid connection

code requirements, Bowman

is currently going through

the process of certifying the

power electronics against the

challenging German market

standards including those of

VDE and BDEW.

Signifcant fuel savings

The Bowman ETC technology

has been tested in a variety of

applications, both on vehicles

and for stationary powergen,

and the benefts are

signifcant. For example, testing

Innovative waste heat recovery

conducted on a Bowman

ETC system ftted to a 900 kW

(continuous) containerised

genset demonstrated

a peak fuel saving of

8.5 per cent for the same

electrical output compared

with the baseline genset.

The fuel consumption data

from these tests highlight that,

in practice, the fuel saving is

consistent across a wide range

of power outputs. This latter

point is particularly important

when considering applications

which have variable outputs,

and also when comparing

with other technologies

which have a narrow band of

optimal performance.

Noting the barriers to

takeup of waste energy

recovery technologies, it is

important to state that the cost

of this technology has been

driven hard through value

engineering activities and

the takeup in certain markets

at reasonable volumes. The

Bowman ETC system is delivered

for less than £1000/kW

(US$1558/kW), comparing very

favourably with competing

technologies such as ORC,

which cost in the region of

£2000–5000/kW. This enables

Bowman to offer a system

which, depending on fuel

cost, can achieve a payback

of signifcantly less than

two years.

Key value models

A couple of examples may

better explain the two key value

models of this technology.

Taking the power boost model

frst, we can examine the

application of the Bowman

ETC system to a Scania DC12-

based genset packaged for

use in the agri-tech market

where feed-in tariffs (FiTs)

are available for installations

burning renewable fuels to

generate power for the grid.

a pioneer in biogas plant

construction, based in Amtzell

Schnell wanted to offer

end users the benefts of

a more effcient genset. In

Germany, the FiTs increase for

all the power generated when

operating above 45 per cent

electrical effciency. The Schnell

265 kW CHP unit is based

on the Scania DC12 engine,

an 11.7 litre displacement,

six in-line cylinders and

1500 rpm machine. In 2009,

Schnell integrated a 30 kW

Bowman ETC system within

the CHP unit. The result was

that the Schnell 265 kW CHP

unit was the frst dual fuel unit

to operate with an electrical

effciency higher than

45 per cent, achieving

48.3 per cent in reference

conditions testing. Almost

500 such systems have so far

been delivered to Schnell by

Bowman Power.

Kalgoorlie Power Systems

(KPS), a subsidiary of

Pacifc Energy, is a leading

provider of power generation

infrastructure to Australia’s

mining and resources sector.

The business executes a

build, own, operate and

maintain commercial model,

with in excess of 250 MW of

contracted capacity at 23

mine sites across Australia. KPS

tenders to provide solutions to

its resource sector client base.

Critical to competitive tender

success and client retention

is the provision of the lowest

fuel consumption generation

infrastructure available.

In 2007, KPS and Bowman

agreed to jointly develop

an optimised Bowman ETC

system solution for retroft

to the Cummins KTA50 G3

engines used in the KPS power

generation feet.

Upon successful completion

of development and trialing,

which demonstrated a

consistent 7 per cent fuel

consumption reduction,

KPS and Bowman entered

into a long-term, exclusive

agreement to supply TGs in

Australia. To date, KPS has

purchased 70 Bowman ETC

systems and is advancing the

rollout of the technology across

its power generation feet.

The above information

and examples describe

applications delivered to date.

However, the technology and

its application continue to be

developed by the engineering

and operations teams at

Bowman. In working with the

current and future client base,

a number of opportunities to

improve the integration of the

ETC system with the host genset

have been identifed and

solutions to these challenges

are now being trialed on

prototype installations.

The frst and most important

of these is the ability of the

system to safely shut itself

down, and take itself out of

the loop, in case of a failure

of some kind which will not

impact the operation of the

host genset. Availability – ‘up

time’ – is absolutely critical in

the vast majority of stationary

powergen installations and

although the ETC system is

key to overall effciency of the

plant, it is peripheral to the

primary function of generating

and exporting power.

Recognising this, Bowman

has worked on the integration

of bypass and regulating

valves, with sophisticated

control algorithms embedded

in the power electronics to

enable the system to be

essentially non-invasive in

functional terms.

Other areas of development

relate, in the main, to

packaging and integration

modularity to suit different

makes and models of host

engine. Many diesel gensets,

for example, are packaged

within ISO containers, and

therefore either a ‘bolt-on’

containerised ETC system is

required, or it is necessary to

integrate all the components

directly on or alongside the

engine within the container.

In the case of on-engine

integration, trials are underway

to rationalise the oil and

cooling systems of the genset

and ETC system to optimise the

packaging from a space and

weight perspective, and also

improve the cost effciency of

the system further.

Other applications

Development is also underway

in respect to broadening

the range of application of

the ETC technology beyond

stationary powergen and

into other environments and

opportunities. There are other

industrial processes which

feature high-temperature and

-pressure waste gas streams

which could be harvested

for electrical energy, as

well as gas fow pressure

reducing requirements which

also offer potential energy

recovery opportunities.

Furthermore, powergen in

marine and offshore applica-

tions is frequently operated on

a baseload basis, offering short

payback opportunity when

coupled with the often high fuel

logistics costs.

It is clear that the

reciprocating engine based

genset has a long future

ahead, burning a range of

fuels in order to generate

power against an ever

increasing demand profle.

While highly mature, the

engine technology remains

characterised by relatively

low overall thermal effciency,

and therefore it is imperative

to continue to seek means

to improve this by recovery of

useful energy from the waste

heat and pressure.

Project Profle: Eastman Business Park, Rochester, NY, US

More than a year

after President

Obama set a

goal to see

40 GW of new industrial-

scale CHP capacity installed

in the US, we are still waiting

to see some results, i.e. some

major new plants being

commissioned. The August

2012 White House executive

order called for a 50%

increase in US CHP capacity

by 2020 to lower both

energy costs and carbon

emissions, and also increase

the competitiveness and

job-creating capabilities of

US industry. The order was

backed up, not with federal

money, but with assistance

from the Department of

Energy to state energy

offcials (see box on p.38).

However, ICF International,

which maintains a database of

US CHP capacity, has identifed

more than 4 GW of new plants

either under development or

being built, and suggests that

we need to wait around two

years – enough time to see a

plant designed, permitted and

built – before real growth can

be measured. Suggestions

are that lowered gas prices

are encouraging chemical

and other manufacturing

businesses back into the US;

with California, Texas and

the Northeast as the likeliest

places to see new plants built.

But, for progress to be

made in overall US CHP

capacity, existing CHP plants

need to be kept in business

through whatever economic

conditions are thrown at

them and, where necessary,

updated. One large-scale

example is the CHP-based

utility infrastructure at a huge

business park in Rochester,

New York, now under new

ownership, to be modernised

including conversion from

coal to gas-fred operation.

The deal has been closed

to transition ownership of

the utility infrastructure at

the Eastman Business Park

(EBP) from the Eastman

Kodak Company, once the

plant’s major customer, to

Illinois-based specialist CHP

developer and operator

Recycled Energy Development

(RED). The park is one of the

largest and most diverse

industrial and technology

complexes in the US, and RED

principals have a 30-year

track record of developing

and operating CHP and

waste-to-energy projects for

industrial companies.

The agreement should

increase energy effciency at

the site, cut carbon emissions,

provide stability for the park

and its tenants, and support

EBP’s revitalisation – the

economic development in

the area is a top priority of the

state government.

Business parks housing a

variety of industrial companies

provide a unique and

potentially very important

niche for effcient, large-scale

CHP-based energy systems, as

suitable multiple heat loads

are usually present. Further,

heat loads at one company

could be matched to ‘waste’

heat streams of another or,

more likely, heat loads can

be amalgamated and served

from one system. A host of

other utilities can be supplied

more effciently, and thus

at lower cost, to a group of

businesses too.

Utility systems at EBPLocated outside Rochester,

New York, close to Lake

Ontario, the 500 hectares EBP

contains over 100 buildings,

230,000 m2 of space and over

80 km of integrated roads and

rail. It was Kodak’s primary

manufacturing site for more

than a century and is still

home to Kodak employees,

but the park now houses

around 35 tenants, including

many from the clean energy

sector. One of the newest is a

battery and energy storage

testing and commercialization

centre for global energy

consultant DNV KEMA Energy

& Sustainability. Another,

due to open next year, is a

research and manufacturing

facility for lithium sulphur

battery materials and

battery-cell  prototypes.

The park’s substantial

energy supply infrastructure

provides up to 125 MW of

electricity, plus steam, chilled

water, compressed air,

industrial water, sewer services,

nitrogen, natural gas and

potable water. It is this that RED

is about to take control of and

upgrade, as part of a wider

deal on the future of the park.

Kodak recently emerged

from bankruptcy, having

failed to adapt suffciently to

the development of digital

photography and having shed

many of the businesses that

made it famous.

RED is acquiring the

comprehensive utilities

infrastructure and over 100 of

the existing employees, and will

continue to supply electricity,

DOE tackles industrial energy effciency Industrial processes – from petroleum refneries

and paper mills to chemicals and metals industries

– consume about one third of all energy produced

in the US, says the Department of Energy. The DOE

sees great potential in expanding what it calls

‘traditional’ technologies like CHP that strengthen

manufacturing competitiveness, lower energy

consumption and reduce harmful emissions.

Last August, President Obama directed

federal agencies to help facilitate investments

in industrial energy effciency, such as CHP

systems, that can save manufacturers as much as

$100 billion in energy costs over the next decade.

The President’s executive order established a new

national goal of 40 GW of new CHP capacity by

2020 – a 50% increase from today. Meeting this

goal would save American manufacturers and

companies $10 billion each year, resulting in

$40 to $80 billion in new capital investment in

plants and facilities that would create American

jobs and reduce emissions equivalent to taking

25 million cars off the road, says the DOE.

The DOE is already helping grow the market for

CHP through its Regional Clean Energy Application

Centers, which provide technical assistance

to US manufacturers, businesses, hospitals and

universities to help them consider the business

case for CHP investments. Since 2009, the centres

have helped numerous organizations understand

how CHP, waste heat to power and district energy

can improve their bottom lines, lower energy bills

and help protect the environment.

The President’s executive order on industrial

energy effciency also directed federal agencies,

including the DOE, to convene regional workshops

to help overcome barriers to expanded CHP

investment. These workshops focus on developing

and implementing state best practice policies and

investment models that unlock new opportunities

in industrial energy effciency and CHP.

The DOE is also expanding its technical

assistance reach, with $11 million over the next

four years to support several regional Combined

Heat and Power Technical Assistance Partnerships

across the country – the next generation Regional

Clean Energy Application Centers. These

organizations will provide fact-based information

on CHP technologies and project fnancing to

commercial and industrial businesses, as well as

state agencies, electricity and gas utilities and

trade associations.

In particular, the coal-fred

boilers are subject to federal

Environmental Protection

Agency MACT rules on boiler

emissions compliance, and

must have extensive emission

controls in place by January

2017 to continue operation.

RED plans eventually to

replace the coal boilers with

combined-cycle gas turbines

and reduce CO2 emissions by

over 700,000 tonnes per year,

while also reducing the cost of

utility services to EBP tenants.

This conversion requires many

steps, including permits,

additional gas supply and

fnancing, and will be a major

focus for the company in the

next few years.

The key to RED’s acquisition

is the company’s willingness

to look beyond the costs and

hassle of applying MACT rules

to boilers which predate the

1970 Clean Air Act. ‘Lots of

bidders looked at the plant but

most were scared off by the

complexity of the purchase.’

says RED president and CEO

Sean Casten. ‘However, the

plant still operates at an

effciency of around 75% so,

by gradually upgrading the

generation plant to a gas and

steam turbines CHP plant, and

keeping most of the existing

energy distribution systems,

we saw a long-term solution to

keeping the park in business.’

The plant cannot be

switched to gas immediately,

though, as there is not enough

natural gas available locally.

Installing a new gas main, with

the necessary permissions

and easements, will take

some time.

Meanwhile, the situation

is complicated further

by regulatory issues over

emissions. Installing back-end

pollution controls on the

existing boilers would be

expensive, says Casten, but

could work. But going down

this route would not only

deliver considerably less

environmental beneft than

conversion to gas-fred CHP,

but would also work against

future conversion. Permitting

for plant changes relies upon

data from the last fve years of

operation and RED needs to

measure improvements from

the current plant arrangement,

rather than one with expensive

new controls installed.

Casten is certain that these

issues will be solved. The park

is a signifcant local employer

and it is in everyone’s interest

to modernise and clean up

the utility system to keep EBP

in business.

What makes the scheme

so iconic is the long history it

shares with Eastman Kodak,

the sheer size of the park,

and the range of utility

products that it provides

to tenants.

meeting held from 13–15

October in Nairobi, Kenya

to discuss the immense

opportunities for Africa and

the challenges and risks that

lie ahead.

Recent reports by Ernst &

Young have noted that East

Africa has emerged as the

new frontier for natural gas

production, boosted by offshore

discoveries in Mozambique,

Tanzania and Madagascar.

E&Y’s Natural Gas in Africa:

The frontiers of the Golden

Age report, released in 2012,

stated that ‘the most dynamic

recent developments in the

African natural gas sector have

been in East Africa’, despite

most of the major players

coming from further north.

In the last fve years, energy

frms including Italy’s ENI and

Anadarko Petroleum from the

US have reported several large-

scale offshore gas discoveries

in northern Mozambique’s

Rovuma basin and Mamba

felds.

David Sweet, WADE executive

director, chaired the panel

‘How Decentralized Energy

Can Deliver Cleaner, Cheaper

and More Effcient Energy in

Africa’. The panel discussions

focused on assessing countries

such as Nigeria as case

studies to see the measures

that were adopted to resolve

power issues. Sweet went on

to discuss how natural gas

can be a game-changer in

the African power scenario. He

also chaired the session ‘Next

Generation of Energy Effciency:

Driving Productivity through

Investment, Modernization and

Education’, which brought

together thought leaders from

government and industry to

discuss a blueprint for the next

generation of energy effciency

and the tools – investment,

modernisation and education

– needed to drive signifcant

increases in productivity.

WADE JOINS HIGH HORSEPOWER SUMMIT IN THE WINDY CITY

With natural gas revolutionizing

North America’s off-road

transportation sector, the High

Horsepower (HHP) summit

held in Chicago, US (known

as the Windy City) from 17–19

September provided the

attendees with an excellent

opportunity to learn about

the fueling, engine and

technology synergies that

exist between marine, mining,

rail, and E&P operations.

WADE was represented by

chair Steve Zilonis at the

event.

WADE CHAIRS GLOBAL GAS OPPORTUNITIES SUMMIT IN ISTANBUL, TURKEYDavid Sweet, WADE executive

director, chaired the two-day

summit supported by the

Turkish Ministry of Energy

and Natural Resources, held

from 1–3 October, which

saw participation of Fortune

500 companies, non-proft

organizations, ministries and

academics. According to Oil

and Gas Journal, as of January

2013 Turkey’s oil reserves stand

at 270 million barrels and

natural gas reserves at 6 billion

cubic metres. With projects

like Trans Anatolian Natural

Gas Pipeline Project (TANAP)

that will act as a passage

between the Caspian Sea

and the Adriatic, Turkey formed

a strategic location for this

summit. Following his opening

remarks, Sweet went on to chair

the regulatory panel discussion

‘Developments in the gas

industry worldwide’.

US HOUSE NATURAL GAS CAUCUS

CO-CHAIRS PROVIDE LEGISLATIVE

OUTLOOK OVER LUNCHThe Business Council for

Sustainable Energy (BCSE),

along with key natural gas

and energy industry trade

associations, hosted a US

Congressional briefng focused

on market trends and policy

drivers for natural gas sectors.

David Sweet, who also serves

as president of the Natural

Gas Roundtable, organized

and chaired the briefng

which featured an overview

presentation by Bloomberg

New Energy Finance (BNEF)

with excerpts from the BCSE-

BNEF Sustainable Energy in

America Factbook, followed

by a moderated industry

panel with senior executives

from a range of natural gas

industry organizations. This

was followed by a panel of

leading natural gas trade

associations on market

dynamics and policy priorities.

Sweet then chaired a lunch

that featured remarks by the

co-chairs of the House Natural

Gas Caucus, Congressman

Tom Reed, Congressman Gene

Green, Congressman Glenn

Thompson, and Congressman

Jim Costa.

WADE PARTICIPATES IN THE

INTERNATIONAL LAUNCH OF THE

NEW IEA GAS AND OIL TECHNOLOGY

NETWORK INITIATIVE

The International Energy

Agency launched its new Gas

and Oil Technologies (GOT)

initiative to governments,

international stakeholders

and press at the GE building

at Rockefeller Center in

New York City, US during

the United Nations General

Assembly. The initiation of the

GOT network addresses a

growing call for collaboration

internationally to pursue

opportunities and experience

transfer on, among other

things, the revolution within

unconventional gas and oil in

the US.

Within the framework of

the GOT initiative, the IEA

is set to work actively with

governments, industry leaders

and academia on the

advancement of technology,

regulatory drivers and

capacities to accelerate the

development of a sustainable,

abundant, affordable and

secure supply of energy for

the world. WADE supports

the mission and David Sweet

addressed the audience over

lunch.

The luncheon meeting

provided a topical context

for the GOT initiative with

presentations from key

stakeholders among

government and industry. IEA’s

new publication Resources to

Reserves: Oil, Gas and Coal

Technologies of the Energy

Market of the Future by Didier

Houssin, director of energy

policy and technology at the

International Energy Agency,

was released at the event.

COMBINED HEAT AND POWER AND WASTE HEAT TO POWER CONFERENCE

IDENTIFIES MARKET POTENTIAL AND NEW TECHNOLOGIES

The Texas Combined Heat

and Power Initiative (TXCHPI),

Heat is Power Association (HiP)

and WADE recently joined

forces to convene CHP2013

and WHP2013 held on

7–9 October in Houston, Texas,

US. The conference attracted

business and energy leaders,

engineering consultants,

project developers, policy

specialists and end users.

The presentations addressed

market enablers and

fnancing, innovations and

emerging technologies, state

and federal policy changes

and the growing demand

for the energy security and

resiliency offered by CHP and

WHP systems in the industrial,

commercial and institutional

sectors.

CHP systems reduce fuel

costs by taking full advantage

of waste heat recovery to

signifcantly increase energy

effciency. On-site generation

with CHP provides energy

security during times of grid

strain and extreme weather

conditions. WHP systems

enhance industrial effciency

by capturing waste heat

from industrial processes,

converting it to power, and

returning the energy back

into the process or exporting

it for others to use. WHP

systems, which require no

combustion and produce

no emissions, improve overall

industrial energy effciency

and competitiveness and are

considered renewable energy

systems in over 15 US states.

As reported at the

conference, there are over

4400 MW of CHP currently

being developed or under

construction, and there is

technical potential for many

more. The potential for WHP

projects is equally impressive,

with more than 11,000 MW

available at industrial sites

as well as gas compressor

stations, landflls and locations

where gas faring is occurring.

Paul Cauduro, TXCHPI

executive director, said,

‘Clearly combined heat

and power and waste heat

to power technologies are

a signifcant part of the “all

the above” energy strategy.

They are a viable and reliable

on-site clean energy option

that can be implemented in

a wide variety of applications.

The existing projects, and the

projects under development,

are proof that these systems

are an integral part of a robust

energy infrastructure.’
