John Cockerill Expands European Electrolyzer Manufacturing Capacity

John Cockerill has commissioned its first French-manufactured electrolyzer stack at Belfort following its 2025 acquisition of McPhy, and is scaling production across Belgium, France, and Germany to supply 40+ MW of capacity for green hydrogen projects in Belgium and the Netherlands. John Cockerill now controls the only integrated electrolyzer manufacturing network in Europe with in-house stack design and three production sites. If you make compressors, valves, power electronics, or cooling systems for hydrogen, you have one buyer in Europe instead of three competing suppliers.
