Mitsui OSK Lines and Air Water have signed Memorandum of Understanding to jointly study the trial use of Liquefied Bio-Methane derived from cattle manure, in LNG fueled vessels.This joint study will be conducted as part of an LBM technology research and development program approved by Japan's Ministry of the Environment and promoted by Air Water. LBM is produced from cattle manure in the Tokachi region of Hokkaido by Air Water. The two companies will confirm that LBM can be transported, supplied, and used without problems using existing shore and onboard equipment. The goal is to use LBM on the MOL Group's coastal LNG fueled vessel in the first half of FY2023. This will be the first use of LBM as marine fuel in Japan.LBM is made by liquefying bio-methane at about minus 160 degree Celsius generated from dairy-owned biogas plants, separating and refining its main component, methane. Methane can be compressed to 1/600th of its volume by liquefying it, so this enables the mass transportation of methane. It is also a carbon-neutral domestic energy source because it is made from cattle manure.
