What John Cockerill Hydrogen does

John Cockerill Hydrogen is a Belgium-headquartered (Seraing) manufacturer of pressurized alkaline water electrolysers and integrated green hydrogen production systems, operating as a subsidiary of the 200+ year-old John Cockerill Group. Its core offering is the DQ-series pressurized alkaline electrolyzer — among the most powerful on the market at up to 1,000 Nm³/h (5–6.5 MW per single stack) — complemented by separation and purification skids, water demineralization, compression and storage, and hydrogen refueling stations (100–1,000 kg/day at 350/700 bar, SAE J2601-compliant). For projects at 100 MW and above, the company delivers turnkey EPC plants through the Rely joint venture with Technip Energies, with the Clear100+ as its productized 100 MW plant offering. Manufacturing is organized as a multi-local network: a 1 GW/year European gigafactory (Aspach cell plant in France, Seraing stack assembly in Belgium) targeting full output by end of 2025, 2 GW/year of capacity in China via the Cockerill Jingli Hydrogen (CJH) joint venture in Suzhou, a planned 1 GW/year US gigafactory in Baytown, Texas by 2026, and a 1 GW partnership with Greenko/AM Green in India.

The company sells primarily through direct enterprise field sales into industrial, infrastructure, and government-backed hydrogen programs, with custom project-based pricing, multi-year contracts, and long sales cycles involving FEED studies and project financing. Revenue streams span electrolyzer equipment sales, turnkey EPC services (via Rely), refueling station hardware, and long-term service and performance agreements. In 2021, the company (via CJH) held roughly 33% of the global hydrogen electrolyzer market with 153 MW delivered; that share was estimated near 20% in 2022 as competitors scaled. Customers include Sinopec (260 MW Kuqa project), Baofeng, AM Green (1.28 GW Kakinada), Nobian/Djewels (20 MW Netherlands), Carmeuse and ENGIE (100 MW Columbus e-methane), and over 35 glass-industry buyers (100+ MW installed), with the installed base approaching 1,000 customers in 30+ countries. The company has been backed by €230M (June 2024, SLB-led) and €116M (June 2025) equity raises, a $34M US IRA tax credit, IPCEI state-aid designation in Europe, and inorganic moves including the July 2025 acquisition of key McPhy assets.
