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.

With a design capacity of 350MW per year of electrolyser production, 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.

All our electrolysers are tested in the assembly bay and a dedicated test lab allows for a full analysis of the electrolysis process. The workshop is ISO 9001 and ISO 45001 and fully habilitated to produce CE certified equipment.

A group philosophy of excellence and a combination of unique experience accumulated over more than two hundred years.
