The energy company will partner with Siemens for the project and use funding from the German Federal Ministry of Economic Affairs and Energy.

Air Liquide is investing €8 billion ($9.4 billion) in the low-carbon hydrogen value chain by 2035, and a total of 3GW electrolysis capacity by 2030.

The Proton-Exchange Membrane electrolyser is set to be operational by 2023 with a capacity of 20MW before being expanded to 30MW. The electrolyser will be integrated into Air Liquide’s existing local pipeline infrastructure to supply key industries and mobility with renewable hydrogen in one of the most industrialized regions of Germany.
