Manufacturing Facilities

A global player with a unique multi-local presence

John Cockerill Hydrogen production sites fully integrate our philosophy of excellence and benefit from our unique combinations of experience and excellence accumulated over more than 200 years.

In addition to being highly automated, we implement the latest techniques in terms of manufacturing, which ensure that our hydrolysers are of unparalleled quality, reliability and efficiency, satisfying all our customers. The integration of the different manufacturing steps in our sites ensures substantial savings, and a rapid response to the markets. This integration is only possible through the complementary nature of the technological solutions offered by John Cockerill.

Europe

Our Franco-Belgian European Gigafactory is a two-site operation aimed at achieving a production capacity of up to 1GW/year by the end of 2025, equivalent to 200 stacks of 5 MW each. The Aspach facility in France has been producing cells since the end of 2023, while the Seraing facility in Belgium is responsible for assembling these cells into the first European stacks.

The launch of this European plant is currently the focus of our efforts, with the aim of rapidly increasing our production capacity and customer deliveries, supplementing the output from our existing plant in China.

The Aspach site benefits from an excellent location in France, next to the German border. Both countries have high ambitions for the development of green hydrogen for their industries. Our assembly site is ideally located close to our headquarters in Seraing, Belgium, which is a strategic crossroads for European exports.

All our electrolyzers are designed, manufactured and tested as required by applicable regulation and design code on the assembly site. The workshop is ISO 9001 and ISO 45001 compliant and fully qualified to produce CE certified equipment.

China

With an electrolyser manufacturing capacity of 1 GW per year, our Suzhou CJH workshop was inaugurated in 2019 and is presently the world’s largest facility dedicated to the manufacturing of electrolysers. The production includes raw material storage, cutting, machining, welding, assembly, testing, packing and expediting. With a total surface of 18,000m², the production site is divided into functional areas: logistics and storage, electrical, machining, electrode workshop, assembly and testing. This ensures quality and full flexibility. As demand for electrolyzers in China continues to grow, a second electrolyzer production plant was built in 2022. This plant has been sized to produce 1 GW per year.

United States & Canada

To support our North American customers pursuing low-carbon hydrogen development, our new Houston-area gigafactory will boast 1 GW per year of annual manufacturing capacity by 2026. This location brings our global expertise and manufacturing experience to the North American market—facilitating adaptation to local norms and standards, streamlining logistics and delivery, and enabling our customers to reduce project risk while meeting domestic content requirements. And with the opening of this facility, John Cockerill Hydrogen continues its practice of a multi-local approach with localized production facilities across Asia, Europe, Africa, the Middle East, and North America.

India

John Cockerill Hydrogen has signed a partnership agreement with Greenko, India’s leading renewable energy company, to set up a 1 GW electrolyser production capacity. These electrolysers will serve the very promising Indian market, estimated at 30 GW by 2030.
