Green hydrogen solutions

At a glance

Green hydrogen at industrial scale: We offer proven, efficient and reliable large-scale alkaline water electrolysis (AWE) technology that operates fully automated and minimalizes the total cost of ownership. With more than 50 years of experience in electrolysis and over 10 GW installed capacity in the chemical industry, our chlor-alkali electrolysis technology is a strong base for the high durability of our AWE technology. The compact cell design enables high current density and space savings. Renowned customers have already selected our AWE technology and benefit from our global service network with the best partners.

20 MW alkaline water electrolysis unit

Our 20 MW alkaline water electrolysis (AWE) unit is setting a benchmark in water electrolysis technology worldwide. This standardized solution for green hydrogen production offers high current density operation with an optimized footprint. And it matches highest market demands: The prefabricated AWE units can be easily transported, installed and interconnected to obtain the desired plant capacity, up to several hundred megawatts or even gigawatts as a cost efficient, highly modularized solution for large-scale green hydrogen production. No carbon involved, no CO2 emitted.

Areas of application


Hydrogen already plays an integral role as feedstock in today’s industry applications. These are mainly ammonia as precursor for fertilizer, methanol as chemical base material, and refining of fuels.

In the future, ammonia is expected to be used as energy carrier which can be shipped and stored. This gives the possibility to connect countries with abundant low cost renewable power with the full spectrum of hydrogen end markets in import countries.


An important future industry application is steel making in which direct reduction of iron ore with green hydrogen replaces the traditional coking process.

Already today, green hydrogen as a feedstock for refineries is an easy entry for green energy into the mobility sector.

In the future, fuel cell mobility as well as sustainable synthetic fuels (e-fuels) will play an important role in otherwise hard to abate sectors such as aviation,

inland vessels, sea going ships, and heavy duty trucks.

To some extent, hydrogen will also be fuel to passenger cars.

Hydrogen is an energy carrier which can be stored over long periods of time and provide seasonal balancing for power markets.

For security of supply, power can be generated back from green hydrogen via turbines or stationary fuel cells.


Also heating accounts for significant emissions today. Hydrogen plays a keyrole in not only decarbonizing industry heat, but also heating for residential and commercial buildings, essentially by replacing natural gas.
