Siemens Energy will supply 12 electrolyzers with a total capacity of 200 MW for Air Liquide’s Normand’Hy project.
Siemens Energy is supplying 12 electrolyzers with a total capacity of 200 MW to Air Liquide’s Normand’Hy project in Normandy, France. Air Liquide will operate the electrolyzers at its plant in the Port-Jerome industrial zone, which will produce 28,000 tons of renewable hydrogen for the industrial and mobility sectors, beginning in 2026.
The low-carbon hydrogen produced with Siemens Energy’s electrolyzers will decarbonize the Normandy industrial basin, displacing up to 250,000 tons of CO2 per year.
"The sustainable decarbonization of industry is difficult without green hydrogen,” said Anne-Laure de Chammard, member of the Executive Board of Siemens Energy. “That is why projects like this are so important. But they can only be a starting point for a sustainable transformation of the industrial landscape. For the development of a European hydrogen economy to succeed, we need reliable support from policymakers and simplified procedures for funding and approving such projects.”
Siemens Energy electrolyzers are built with proton exchange membrane technology (PEM electrolysis), offering a brief ramp-up time and dynamic controllability that enables integration with intermittent renewable energy supplies. The PEM electrolyzers feature a high energy density while leaving a small environmental footprint with minimal material requirements.
Air Liquide’s Normand’Hy project will be supplied with electrolyzers manufactured at Siemens Energy’s production facility in Berlin. Industrial-scale production of stacks—a key component within the PEM design—will begin in November of this year. Siemens Energy projects manufacture to scale up to 3 GW per year by 2025, enabling the company to provide electrolyzer technology to projects internationally.
