ClassNK points assertion of reality for methane slip discount system developed by Hitachi Zosen, MOL, and Yanmar PT

An idea of the methane oxidation catalyst system, a tool is designed to scale back methane slip by putting a methane oxidation catalyst within the exhaust piping of an LNG-fuelled engine and oxidising the unburned methane on the catalyst, was designed by Hitachi Zosen and Yanmar PT as a part of a undertaking which was adopted by Japan’s New Vitality and Industrial Know-how Growth Group (NE-DO) as ‘Growth of Methane Slip Discount Know-how from LNG Fuelled Vessels by Bettering Catalysts and Engines’ below the Inexperienced Innovation Fund, and ClassNK issued approval in precept (AiP) for that conceptual design. On this undertaking, the companion corporations purpose to attain a methane slip discount price of greater than 70% for LNG-fuelled vessels over a six-year interval from FY21 – FY26. The discount might be achieved by combining methane oxidation catalysts and engine enhancements thereby additional decreasing the environmental influence of LNG-fuelled vessels.

Based mostly on the take a look at process submitted by Yanmar PT, ClassNK has issued a SOF upon confirming the methane slip discount impact below LNG combustion situations of marine dual-fuel engines outfitted with a methane slip discount system.

Beginning round autumn 2024, a big coal service operated by MOL is deliberate to bear trial in precise sea areas. ClassNK will proceed to make sure the surroundings for the early institution of decarbonisation applied sciences by offering technical verifications for superior initiatives.
