Johnson Matthey has launched its first hydrogen internal combustion engine (HICE) testing facility in Gothenburg, Sweden, aimed at advancing zero-carbon propulsion technologies for medium- and heavy-duty transport. The £2.5 million facility enables full-scale testing of hydrogen-fuelled engines, enhancing JM's testing capabilities and supporting regulatory demands for cleaner transport. The project builds on prior collaborations and positions JM as a leader in sustainable technology solutions.
