THE BORN OF A NEW TECHNOLOGY

Acta’s R&D team introduced the AEM Electrolysis in 2009:

Developing dedicated CATALYSTS

Optimizing the MEA (Membrane Electrode Assembly)

Assembling the first stack

17

AES stack key facts

HIGH ENERGY EFFICIENCY< 4.0 kWh for 1 m3 H2

LOWER COST than PEM

HIGH H2 PURITY(>99,9% without DRYER)

LESS STRINGENT WATERREQUIREMENTS than PEM

SIMPLE BALANCE OF PLANT(AIR COOLING, etc)

SELF‐PRESSURIZED at 35 bar

6. Examples of AEM Electrolyzer application

Increasing AEM Market penetration and recognition

09.05.2016Alberto Carpita| Heliocentris Group 2016

Many deployments in tens of countries in all the main continents

Facing real in‐field conditions from ‐40’C up to +55’C and harsh environments

Increasing numbers of customers recognizing the benefits of AEM

Partnering with worldwide market leading companies

27

Location: Chiang Mai,Thailand

Project: 24hour supply of energy from solar and stored hydrogen for residential house

Project: Combination of Solar, Battery, Electrolyzer and fuel cell

114kW PV system

EL maximum production rate: 2,000 L/hour

Storage capacity of hydrogen ca. 130kWh

Field Example 1) CNX construction – Phi Suea House

28

Location: Yarra Ranges National Park, Australia

Challanege: to supply back-up under Climatic variability for an isolated locatily

Solution: provision back-up power by solar, electrolyzer, fuel cell system

Rain water can be used

Back-up power for up to 10 hoursCan be extended by adding more tanksSystem successfully was used in several power outages already

Long autonomy and low logistic/mainteance

Field Example 2) Telstra – Back-up for telecommunication

29

Location: Alps, Refuge of Col du Palet, 2600m above sea level

Project: Energy Independence for totally isolated site

Solution: solar, AEM electrolyzer, fuel cell system

Seasonal balancing and long-term storage

Hydrogen generated in winter is used in summer time for electriity production

Field Example 3) Powidian – Refuge Camp in the Alps
