Mitsui O.S.K. lines (MOL), Kanadevia and Yanmar power solutions have achieved a 98% reduction in methane slip during onboard trials of LNG-fuelled vessels – significantly exceeding the initial 70% target. The demonstration, part of Japan’s green innovation fund project led by the new energy and industrial technology development organization, began in May 2025 on routes including between Japan and Australia.
The project combines methane oxidation catalysts with engine design to reduce unburned methane emissions, which has a higher greenhouse effect than CO2. It follows earlier land-based tests that achieved 93.8% reduction at full load and earned certification from 'ClassNK'. Onboard trials will continue through FY2026, with social implementation targeted for FY2027. (js)
