Johnson Matthey, has taken the next step in its plans to commercialize technologies to enable production of zero carbon green hydrogen, announcing new manufacturing capacity for the production of catalyst coated membranes. This capacity is co-located at JM’s plant in Swindon, UK, where fuel cell components including membrane electrode assemblies, catalyst coated membranes, and fuel processor catalysts are produced at scale.

JM specializes in catalyst coated membranes which sit at the heart of electrolyzer units and enable the green hydrogen production process, creating hydrogen through the electrolysis of water with no harmful emissions.

The new capacity enables JM to produce components now, initially for tens of megawatts of hydrogen production – enough to power several thousand homes. The largest electrolyzer units in operation in the world today range from 10 to 20 MW. As such, the new capacity puts JM in a position to work with world scale projects, with a roadmap to scale to multi-gigawatt manufacturing capacity in line with customer demand as the market continues its anticipated growth.
