Hydrogen Electrolyzer Cooperative

Siemens Energy and Air Liquide joint venture

Siemens Energy and Air Liquide are forming a joint venture headquartered in Berlin dedicated to the production of industrial-scale renewable hydrogen electrolyzers. Siemens holds 74.9%, while Liquide gets 25.1%.

This partnership will stimulate further interest of hydrogen in Europe. Initial start is late 2023, reaching an annual production capacity of 3 GW by 2025.

A multi-GW stack factory will also be located in Berlin. This factory will supply stacks to both of the partners and the market. Based on proton exchange membrane (PEM) electrolysis, the stacks are suited to harvest volatile renewable energy.

They have also agreed to dedicate mutual research and development efforts for the next generation of electrolyzer technologies.

The partnership will aid large industrial-scale hydrogen projects through the combination of their pipelines, increasing electrolysis capacities. One of the first projects is located in Normandy, France, and has a capacity of 200 MW.
