About us


5/30

Work towards a power supply, in which all energy isgenerated CO2-free and from renewable sources

Develop reliable up-to-100-percent renewable energysystems that can outcompete fossil-based systems today

Since 2006 we have been continuously identifyingcommercially viable energy storage technologies

Combine highly reliable storage technologies withinnovative grid control and energy management solutions

Younicos AG was founded in 2008 with approx. 70employees today

What we do

Consulting Planning Development Construction Operation

The Challenge


7/30

Core challenge in moving to 100% renewables-based energyeconomy is integrating fluctuating energy sources into ourelectrical grids both technically and commercially

Identifying industrially available and commercially viableenergy storage technologies

Providing safe, stable and competitively priced powersupply based on sun and wind

Pioneering innovative market models in which thetransition to renewables reduces overall economic costwhile providing attractive returns for outside investors

The challenge


8/30

Identification of suitable storage solutions for different

applications


9/30

We investigate what technology is

being developed that isinexpensive, suits renewableenergy applications, is versatilefor any kind of user environment,environmentally friendly, safe,ageless, ..?

Almost seven years of experiencewith storage technologies.

We are at the forefront of the lateststorage technologies

Ongoing storage technology evaluation - mostly electrochemicaltechnologies and mostly theoretical evaluation

Identification of suitable storagesolutions for different applications

High power High energy

Li-Ion Redox flow NaS


11/30

We conduct ongoing lithium iontechnology evaluation

Current R&D and commercial sample testing

What are the current developments in R&Dthat will soon be translated into massproduction?

What are the current trends for batterymanufacturers?

Are there improvements regarding costs,safety and longevity?

Who could be our partner?

We find the answers with regular conferencevisits, company visits and sample battery celltesting in our laboratory.

Viewpoints on lead acid versus lithiumion battery technology

1. Environment

2. Energy

3. Costs


13/30

1. Environment

Lead is a heavy metal and highly toxic to human and theenvironment. Especially in developing countries with lowlevel of education, the recycling of batteries is often

used to generate income causing a huge threat to thehealth of people. With an increasing lead price thisnumber will increase.

At least 27 mass poisoning incidents since 2005 in Chinaonly


14/30

2. Energy

Related to the possible energy throughput during usage the

energy consumption for production of lead acid batteries isminimum 1.5 times higher and the CO2 emissions are 3 timeshigher in comparison with lithium ion

In combination with PV for autonomous energy supply theenergy return factors are:

Lead acid battery: 5

Lithium ion battery:8.5

Best case:

a PV-battery system with lead acid batteries generates only 5 times the energy which was consumed during its

production (PV, PCS, transport, battery exchange).

Worst case:

above system is operated at higher ambient temperatures (40C), manufactured from lead ore

(China) instead recycled material and transported by air, then the energy return factor turns into 0.25. Four

times more primary fossil energy is needed to produce the system than what is replaced.

Initial investment versus operation costs

Lead acid batteries

Need more maintenance

Age faster at higher ambient temperatures

Need to be exchanged more often

Can not be fully discharged (no 100% DOD)

Therefore the installed size is bigger and because of higherweight the transportation costs are higher

20/30

On our campus in Berlin, we have built a megawatt scaletechnology center containing actual hardware needed to run gridsbased on 100% renewable energy sources. In addition todemonstrating our innovative grid control and energymanagement strategies, this center also provides:

Younicos Technology Center also provides:

component supplier qualification

technical due diligence

new technology certification

employee and partner training

Younicos Technology Center


21/30

Younicos designed intelligent inverter, energy management, andbattery power plant systems

Various battery technologies: a 1MW/6MWh sodium-sulphur (NaS)unit; a 200 kW/200kWh lithium-ion unit; and several 5 kW/ 4

kWh lithium-titanate units Transmission grid with 2-8 km of 15 kV medium voltage line

Wind, solar, and load simulators capable of recreating actualenergy flows anywhere on the planet based on high-resolutiondata

Battery test laboratory where we have evaluated over 10,000lifetime cycles of various battery cell technologies

Island Project: Graciosa


23/30

The Graciosa project

Younicos is building a megawatt scale energy grid capable ofrunning without a fossil fuel generator on the Azorean islandof Graciosa in the middle of the Atlantic ocean.

4500 inhabitants 100% renewable generationduring the majority of the year

>70% of total annual consumptiongenerated by renewable sources

Competitive against current system

In cooperation with the local utility

Project start: 2012

Storage 2,5 MW

Solar Power 500 KW

Wind Power 5,4 MW

Storage for grid stability


25/30

Battery parks

We implement automated, turn-key megawatt-scale batteryparks with 20 year performance guarantees.

Industrial scale storage balances power supply and demand,keeping grids stable and allowing for more use of renewables

Grid operators benefit from faster, more accurate, cheaper andCO2-free frequency regulation than currently provided bythermal power plants

Industrial power users in areas with unreliable or unstable

grids (blackouts, microcuts) benefit from stable frequency andvoltage


26/30

Vattenfall project


27/30

Vattenfall project for frequency regulation

We have integrated the first megawatt scale battery into theEuropean grid

Battery participates in the German primary reserve energy market

In cooperation with Vatenfall, one of Europes largest utiltities

The power control and grid communication strategies we havedeveloped allow the battery to contribute to balancing out gridinstabilities within milliseconds, less than a fraction of the 30seconds required by the current reserve energy market rules.

Web2Energy project


29/30

The Web2Energy project

As the partner for storage technologies in a Europeanconsortium we helped the German utility HSE AG establish aSmart Grid by installing communication links between powerproducers, grid terminals and consumers.

We developed and deployed intelligent Lithium-Ionstorage units

We also integrated two Vanadium Redox-Flow batteries intothe grid

In a global first, these units communicate using the IEC 61850standard that all power plants in the European continentalgrid use
