Johnson Matthey buys into lithium-sulfur for green hydrogen
Johnson Matthey has bought the assets and intellectual property of UK lithium-sulfur pioneer Oxis Energy in an undisclosed deal

Johnson Matthey will use the lithium-sulfur technology from Oxford-based Oxis Energy for the manufacture of components for green hydrogen production. Oxis entered administration on 19 May 2021, and was building a chemical factory in Wales which will boost the capacity for hydrogen electrolyte components.

With moderate additional investment in upgrades, the deal will significantly accelerate the scale-up of JM’s growing green hydrogen business says the company, which does not rule out developing batteries. Lithium-sulfur is a promising technology for electric aircraft power.

The former Oxis factory in Port Talbot will further expand JM’s ability to develop, test, and manufacture catalyst coated membranes and advanced materials for electrolysers, as this market continues to develop very rapidly and in response to positive progress with customers. The site will enable the production of tens of thousands of catalyst coated membrane parts per year, enough to equip hundreds of megawatts of electrolyser capacity.

In addition to accelerating green hydrogen scale-up, the acquisition of a considerable IP portfolio in next-generation lithium-sulfur and adjacent battery technologies presents opportunities for JM’s battery materials business to advance its development of future battery material technologies.

“Acquiring Oxis Energy’s assets enables us to support our customers as they meet the strong demand for proton exchange membrane electrolysers used to produce green hydrogen. Improving electrolyser efficiency and reducing the cost of hydrogen are key to the further development of the green hydrogen market and scaling up CCM manufacturing will help bring JM and our customers closer to achieving this goal,” said Eugene McKenna, Managing Director Green Hydrogen

“We are delighted to secure this acquisition,” said Robert MacLeod, Chief Executive of JM. “The capability this opportunity delivers will enable our green hydrogen business to accelerate the scale-up of CCM production in line with market demand. The purchase of these assets further demonstrates our commitment to developing a low carbon economy and progressing towards net-zero.”
