Japan Engine Corporation (J-ENG) and Kawasaki Heavy Industries have started onshore testing of a large, low-speed, two-stroke hydrogen-fueled marine engine.
The test campaign, the first of its kind, marks the world’s first operation of a hydrogen propulsion system designed for large ocean-going vessels.
The prototype engine, designated 6UEC35LSGH, completed initial hydrogen co-firing trials at J-ENG’s factory in Hyogo Prefecture.
Tests confirmed stable combustion across all six cylinders, with hydrogen accounting for more than 95 percent of fuel energy at full load.
Japan’s new hydrogen engine
During the testing campaign, the 6UEC35LSGH engine maintained reliable performance while delivering significant greenhouse gas reductions compared with conventional diesel operation. The engine has great potential for accelerating the decarbonization of the shipping industry.
J-ENG developed the engine in collaboration with Kawasaki Heavy Industries, with the latter supplying the liquefied hydrogen fuel supply system. The project forms part of the New Energy and Industrial Technology Development Organization’s Green Innovation Fund initiative for next-generation ship development.
