Cosmo Oil Marketing Co., Ltd. (hereafter “the Company”), a subsidiary of Cosmo Energy Holdings Co., Ltd., is pleased to announce its participation in the Project for Ship-to-Ship Biofuel Bunkering in the Port of Tokyo (hereafter “the Project”), with NX SHOJI CO., LTD. (hereafter “NX Shoji”) serving as the representative constituent. The Project was selected to receive a subsidy under the Commercialization Promotion Support Project for the Utilization of Decarbonized Fuels, a collaborative effort organized by the Tokyo Metropolitan Government and Tokyo Environmental Public Service Corporation to support biofuel initiatives¹.

Scheduled to start this fall, the Project will leverage NX Shoji’s biofuel bunkering scheme to supply B24 fuel, a blend of heavy fuel oil A and biofuel (FAME²), to ships used by the Company and vessels of other participating companies that call at the Port of Tokyo. As part of this effort, the Company will supply heavy fuel oil A as feedstock, while NX Shoji handles the blending. The resulting biofuel will then be delivered to the Company’s ships.

In addition, through the introduction of biofuels, the Company will contribute to achieving the Tokyo Metropolitan Government’s Zero Emission Tokyo Strategy and to a sustainable society.
