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.
