Siemens Energy and the French gas manufacturer Air Liquide want to build electrolysers for hydrogen from renewable energies. An annual production capacity of 3 gigawatts is to be achieved by 2025, as the two companies announced on Thursday. This corresponds to the output of 200 to 300 large wind turbines at sea. The start of production is planned for the second half of 2023. The two companies had already announced in February that they wanted to work together on the development of electrolysers on an industrial scale.

The two companies had already announced in February that they wanted to work together on the development of electrolysers on an industrial scale.

SiemensEnergy will have a 74.9 percent stake in the joint venture, which is to be based in Berlin. The group is contributing its electrolyser production facility, which is being built in the capital, with an investment volume of around 30 million euros. In addition, both companies want to jointly research the next generation of electrolyser technologies.

“The establishment of this Franco-German joint venture is an important step towards becoming a leading European renewable and low-carbon ecosystem hydrogen», said Air Liquide boss François Jackow. “By expanding large-scale production of electrolysers, Air Liquide and Siemens Energy will be able to provide their customers with access to large volumes of competitive renewable hydrogen and decarbonize their operations.”

Energy boss Christian Bruch emphasized: “In order to make green hydrogen competitive, we need mass-produced, cost-effective and scalable electrolysers. We also need strong partnerships.”
