Manufacturing Facilities

Soon a new manufacturing site in France for the production of hydrogen electrolysers

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.

John Cockerill has announced that it will reach 8 GW of production capacity by 2025. To achieve this, we are acting globally.

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.

USA

John Cockerill announced its entry into the North American market with a new gigafactory in the Baytown area outside of Houston, where we will operate the first alkaline electrolyzer gigafactory in the US. With a long history as an energy hub, Houston has the skilled workforce, infrastructure, and local support necessary to expand further and establish the region as a clean energy hub as well. We expect the first electrolyzer produced at the facility to be ready before the end of 2024, with full ramp up achieved in 2026. The facility is expected to produce 1 GW per year of electrolyzers, creating 200 jobs and bolstering Houston’s position as a hydrogen hub.

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.
