• Customer demand for environmentally friendly
solutions
– To help meet carbon reduction commitments
• Linnet Tech leading the way with the
introduction of hydrogen fuel cell UPS/backup
power systems for zero emissions with
partners Auriga Energy
• Auriga Energy is a developer of high efficiency
fuel cell systems drawing on experience in the
space, offshore and defence industries

First deployment
• In 2008, one of our clients, the Met Office,
requested that Linnet Technology and
Auriga Energy form a collaborative
partnership to support the evaluation of
Hydrogen Fuel Cell UPS and backup
power systems.

The drivers
• Concern on Climate Change
• Levels of toxic pollution
• Ever increasing demand for energy
• Dependence on imported energy supply
– Price of oil & gas
• Numerous governmental initiatives
– EU launched “post-industrial revolution” Jan 07
– UK Climate Change Act 2008
• Reduce carbon emissions by 34% by 2020, 80% by 2050
• Scotland commitment to reduce by 42% by 2020

Drivers for Technological
Change
• Remote stations where electrical and fuel oil services are difficult
• Ongoing need to reduce maintenance costs
• Desire to remove diesel generators with inherent noise and environmental pollution risk
• Need for greater efficiency and long term cost benefits
• Effective technology that operates efficiently in adverse weather conditions and wide temperature ranges
• Technology that provides reliable operation after extended shutdown time

Hydrogen as a fuel
11
• Hydrogen = most abundant + oldest element
• Currently produced for the chemical industry
– Production growing with population and industry
• E.g. 2/3 of H2 produced by Air Liquide is for de-
sulphurisation of hydrocarbons for fuels without sulphur
• Readily available from UK suppliers and can be
generated near the point of use
• Combine hydrogen and oxygen to produce lots
of energy and only water as output
• Fast refuelling < 3-5 minutes
A sustainable fuel

UPS/Backup Power• A single solution providing both UPS
and backup generator
• Modular to allow growth
• Operational runtime virtually unlimited
– Can be primary generator
• Clean, quiet operation indoors or
outside
– No planning permission required
• Wide operational temperature
tolerance -20ºC to 50ºC
• Low Through Life Cost
– Reduced maintenance, repairs, transport
and disposal15

Running costs
Diesel• C11 D5 diesel generator fuel
consumption = 2.7L/h
• Therefore, fuel used in an 24
hour continuous run = 64.8L
diesel/day
• Daily cost of diesel = 64.8 x
£1.409/L = £91.30/day [av.
Nov 2011 price – The AA]
Fuel Cell
• H2 consumption (full power) =
140slpm = 201,600L/(24h)day
• H2 density = 0.08988 x 10-3kg/L
• H2 consumption = 201,600 x
0.08988 x 10-3 = 18.12kg/day
• Price of hydrogen for large
quantity ~ £3.33/kg [ref US
prices at exchange rate 1.5]
• Daily cost of hydrogen = 18.12 x
3.33 = £60.33/day
17
Potential savings per day =
£91.30 - £60.33 = £30.97/day
Potential savings per year =
365 days/yr x 30.97 =
£11,304/yr

Carbon reduction
• Rough point of ref.;
• Cummins C11 D5 is 1.65L capacity
• 1.6L ICE in a road vehicle emits 166.2g CO2 eq/km
using petrol (EU Commission Joint Research Centre)
• At an average equivalent of 50km/hr, C11 D5 will do
approx 1200km/24h-day in continuous operation
• CO2 eq. emissions per day = 199.44kg
Potential for over 72 Tonnes of CO2 reduction per year

Diesel Fuel Cell
• Regular pressure/fuel
gauge check
• Filter change annually
Other Factors
• Continuing rise in the price of diesel
• Likely reduction in the price of
hydrogen as usage increases.
• Likely improvement in the $/£
exchange rate for the comparison
• The higher maintenance cost for
diesel engines
