John Cockerill Hydrogen is the dedicated hydrogen business of the John Cockerill Group, a long-established Belgian industrial company headquartered in Seraing with origins dating to 1817. It focuses on the development, manufacturing, and servicing of pressurized alkaline electrolyzers used to produce green hydrogen via water electrolysis powered by renewable energy sources.
The company designs and supplies electrolyzer stacks with capacities up to 5 MW (among the largest single-stack units available), complete balance-of-plant systems including gas separation, purification, and power supply, as well as hydrogen refueling stations and integrated EPC solutions for large-scale hydrogen production plants. Its technologies target decarbonization in heavy industry, chemicals, steelmaking, green ammonia, sustainable aviation fuels, and mobility sectors.
Operations span manufacturing and assembly facilities in Seraing (Belgium), Aspach and Belfort (France), and Wildau (Germany), with additional capabilities in China stemming from earlier joint ventures and asset acquisitions. Expansion includes a planned gigafactory in Baytown, Texas (USA), and partnerships for facilities in India. The business has delivered more than 1,300 electrolyzers to projects in over 30 countries and maintains a substantial order backlog.
Structured as a subsidiary within the broader John Cockerill Group (which operates across energy, defense, and industrial equipment), John Cockerill Hydrogen is recognized as one of the leading global suppliers of alkaline electrolyzer technology, emphasizing proven reliability, large-scale deployment, and support for the growing green hydrogen economy.
Also known as Cockerill Jingli Hydrogen.

Targeting: Hydrogen (1)
First 5 MW electrolyzer stack assembled in Belfort; Aspach to produce eight electrolyzers (40 MW) for a Dutch project; 25 MW previously supplied to Belgium.
Project reached FID/NTP and moves into construction. Will use John Cockerill pressurized alkaline electrolysis; first hydrogen expected mid‑2028; plant ties into local Chemical Park and Nobian.
The program aims to advance AEM electrolysers, focusing on safety, energy management, and cost efficiency, using PGM-free technology for sustainable hydrogen production.
HyCC's Djewels project in Delfzijl will use McPhy's electrolysers and Technip Energies' design to produce 3,000 tons of green hydrogen annually, aiding European decarbonization and climate goals.
The €11M grant supports a 20 MW electrolyzer in Delfzijl, converting renewable electricity to green hydrogen and methanol, reducing CO2 emissions by 27,000 tons annually.
