Siemens Energy and Air Liquide form venture for production of hydrogen electrolysers

news item image
Siemens Energy and Air Liquide have announced a joint venture dedicated to the series production of industrial scale renewable hydrogen electrolysers in Europe.
The Franco-German partnership will enable the emergence of a sustainable hydrogen economy in Europe and foster a European ecosystem for electrolysis and hydrogen technology.
Production is expected to begin in the second half of 2023 and ramp-up to an annual production capacity of three gigawatts by 2025.
Air Liquide will take 25.1%, and Siemens Energy will hold 74.9% of the joint venture, which creation remains subject to approval of the competent authorities.
This joint venture will be headquartered in Berlin. The joint venture multi-gigawatt factory that produces electrolysis modules will be located in the German capital, as announced earlier this year.
This factory will supply stacks to both Groups for their respective broad range of customers and to serve the rapidly growing market.
Based on proton exchange membrane (PEM) electrolysis technology, these stacks will feature a high degree of efficiency and are ideally suited to harvest volatile renewable energy.
In addition, Air Liquide and Siemens Energy have agreed to dedicate R&D capacities to the co-development of the next generation of electrolyser technologies within the framework of the partnership.
The strategic partnership will benefit from a portfolio of hydrogen projects combining both Air Liquide and Siemens Energy’s pipelines, targeting large industrial-scale hydrogen projects in collaboration with customers.
This will create a solid basis for the required rapid ramp-up of electrolysis capacities and thus is expected to make competitive renewable hydrogen available sooner.
One of the first projects is the Air Liquide Normand’Hy electrolyser project, with a capacity of 200 megawatts (MW) expected in the first phase, located in Normandy, France. The assembly of the electrolyzer systems for this project is planned to be made in France.
