Kawasaki Heavy Industries and Japan Suiso Energy have contracted to construct a 40,000 cubic meter liquefied hydrogen carrier, the largest globally. This vessel will support a commercial hydrogen supply chain demonstration funded by Japan's Green Innovation Fund and led by the New Energy and Industrial Technology Development Organization.

Built at Kawasaki's Sakaide Works, the carrier will load hydrogen at a new terminal in Kawasaki City and undergo ocean-going trials by 2030. It will feature a hybrid propulsion system using oil and hydrogen, employing a dual-fuel generator engine that utilizes hydrogen gas from boil-off in the cargo tanks. Designed for efficiency with advanced insulation and safety features, the vessel aims to minimize emissions during transit while ensuring safety and durability in trials before its global deployment.
