Details
Technology & product
Carbon Reductionup to 250,000 tonnes of CO₂ avoided per year
Configuration DetailSiemens Energy announced a supply package of 12 PEM electrolyzers totaling 200 MW for Normand'Hy.Air Liquide said in July 2025 that Normand'Hy requires a total of 288 individual electrolyzer stacks, manufactured at its Berlin joint venture with Siemens Energy.
FeedstockThe site is designed with access to water drawn from the Seine, which is treated and purified on site.
Final Useindustry and heavy mobilityMost of the hydrogen is planned to supply the nearby TotalEnergies refinery for desulfurization and other refining processes, with additional volumes for intensive mobility along the Seine axis.
Power Sourcerenewable electricity
