MOL says hydrogen — fueled engine for large commercial ships cuts GHG emissions by over 95% in land tests

Mitsui O.S.K. Lines-backed project completed land-based tests of a hydrogen-fueled main engine for large commercial vessels. Factory trials reached at least 95% hydrogen co-firing, cutting GHG emissions by more than 95% versus heavy-fuel-oil engines. Engine uses high-pressure direct injection to stabilize hydrogen combustion, targeting commercial-scale marine propulsion applications. Deployment planned on a 17,500 DWT multipurpose vessel; installation scheduled for January 2027, onboard demonstration from April 2028.
