Hydrogen from water electrolysis - solutions for sustainability
Green hydrogen for energy storage, sustainable chemicals, mobility and more
Renewable energy is used optimally if every single watt produced can be consumed or stored. With industrial-scale water electrolysis, hydrogen as a clean energy carrie can be produced by simply splitting water. Hydrogen can be stored and reconverted into energy, or directly used to feed it into:
the gas grid
chemical production (ammonia, methanol, synthetic natural gas, ...)
fuel cell vehicles

Current discussions on water electrolysis include mainly two different methods – alkaline water electrolysis and PEM water electrolysis. While the former is regarded as a robust, low-CAPEX method, the latter stands for high flexibility and low OPEX. As neither of these technologies will serve future demands, we have come up with our own technology that combines the best of both.
We provide hydrogen generation devices that use surplus electric power, life-support devices in the closed area, and a pure water electrolysis method using an oxygen generation device to supply oxygen. High-purity hydrogen and oxygen can be generated using a zero-gap structure and high-performance membrane. The results:
The water electrolysis process is in use around the world for several decades, mainly in installations serving small-volume industries such as glass making, organic hydrogenation, generator cooling applications etc. In the fertilizer industry it was always an option when cheap electricity was available and there were no other sources of hydrogen.
As in the future the focus will be more on integrating renewable energy sources in a cross-sector approach, hydrogen will have a very important role to play – hence the need for improved power to hydrogen technology.
