Cosmo Oil announced on September 5 that it will launch a ship-to-ship (STS) biofuel bunkering project at Tokyo Port this fall in partnership with logistics and transport company NX Shoji. The initiative has been selected as part of the “Decarbonized Fuel Commercialization Promotion Project” led by the Tokyo Metropolitan Government and the Tokyo Environmental Public Service Corporation.

Under the plan, Cosmo will supply B24 fuel—a blend of A heavy oil and fatty acid methyl ester (FAME)—to vessels departing from or arriving at Tokyo Port. The project, backed by local government support, aims to accelerate the commercialization and adoption of marine biofuels, strengthen Tokyo Port’s role as a green hub, and promote the development of related industries in line with global shipping decarbonization efforts.
