Cosmo Oil SAF

Cosmo Oil Co., Ltd. functions as a primary energy supplier within the Japanese aerospace value chain, transitioning from traditional petroleum refining to the large-scale production of Sustainable Aviation Fuel (SAF). The organisation is positioning itself as a critical upstream provider to decarbonise the domestic aviation sector, leveraging existing refinery infrastructure to establish integrated supply chains from feedstock procurement to airport hydrant delivery. Through a joint venture named SAKURA SAF NEXT, the company is developing Japan's first large-scale domestic SAF production facility at the Sakai Refinery. The organisation maintains strategic partnerships with major Japanese carriers, including Japan Airlines (JAL) and All Nippon Airways (ANA), for the future uptake of bio-based fuels. It also collaborates with engineering firms and international technology providers to implement Alcohol-to-Jet (ATJ) and Hydroprocessed Esters and Fatty Acids (HEFA) conversion processes. Prospective partners or fuel buyers should verify the specific commercial operational dates of the Sakai production facility and the certification status of the fuel batches against ASTM D7566 standards. It is also necessary to confirm the sustainability credentials of the raw feedstocks used, such as used cooking oil or ethanol, to ensure compliance with international CORSIA requirements and regional carbon reduction mandates.
