French gas specialist Air Liquide and German energy engineering group Siemens Energy continue to invest jointly in hydrogen as a future technology. A milestone is now being set in Oberhausen: With a capacity of 30 megawatts (MW), the largest electrolyzer in Germany connected to an existing hydrogen infrastructure is being built here. The new proton exchange membrane (PEM) electrolyzer, which is being built by Air Liquide, will produce climate-neutral hydrogen from water and renewable electricity. The technological solution for the project is being developed jointly with partner Siemens Energy.
By 2023, the two companies plan to commission a plant with a capacity of 20 MW in the first phase, which will produce 2,900 metric tons of climate-neutral hydrogen per year as well as climate-neutral oxygen. In the second phase, the capacity will then be increased to 30 MW.
François Jackow, Executive Vice President and Member of the Executive Committee of the Air Liquide Group: "By utilizing Air Liquide's existing hydrogen pipeline network, the renewable hydrogen produced will accelerate the decarbonization of the Rhine-Ruhr industrial region and promote clean mobility in a densely populated region."
Air Liquide's German headquarters in Düsseldorf, where 4,500 employees work, serves around 100,000 customers in Germany.
