SAFFAIRE SKY ENERGY LLC Established for the First Large-Scale Domestic Production of SAF

JGC Holdings Corporation is pleased to announce the establishment of SAFFIARE SKY ENERGY LLC with Cosmo Oil Co. Ltd. and REVO International Inc. on November 1 of this year for domestic production and supply of sustainable aviation fuel (SAF) from used cooking oil.

Joint study of the feasibility of commercialization, with the aim of building a domestic supply chain from collection of used cooking oil to production, transport, and supply of SAF, has been underway by the three companies since the summer of 2020. The new company will target annual SAF production on the level of 30,000 kiloliters, seeking to become the first large producer of SAF in Japan. The fuel will be sourced entirely from used cooking oil. In anticipation of the second half of fiscal 2024 to the beginning of fiscal 2025 start date, construction of the SAF production facility will begin in the summer of 2023 at Cosmo Oil’s Sakai Refinery in Osaka, with completion expected by the end of 2024. In addition to SAF, the plant will also produce bionaphtha (a raw material for bioplastic) and biodiesel.

This project pertains to a call for proposals from Japan’s New Energy and Industrial Technology Development Organization (NEDO) to develop SAF production technologies. The safe and stable fuel supply chain will be established by combining the knowledge and expertise of each company, with REVO International and JGC Holdings responsible for raw material procurement and the Cosmo Energy Group (Cosmo Oil and Cosmo Oil Marketing Co., Ltd.) responsible for SAF production and sales to customers. Design, procurement, and construction for this facility will be undertaken by JGC Japan Corporation.

Saffaire in the new company name derives from a combination of “sapphire” (a gemstone) and “SAF.” With the deep blue of sapphires often symbolizing an unwavering spirit, this represents our commitment to carry through on our goal of helping to decarbonize the aviation sector.
Behind this combination of the blue of sapphires and “Sky Energy” lies a hope that the new energy source of SAF can help keep our skies blue.

JGC Holdings, Cosmo Oil, and REVO International have been members of ACT FOR SKY, a voluntary organization established on March 2 of this year to introduce, promote, and expand domestically produced SAF, since its inception. We believe that the establishment of this new company will be a major step toward achieving ACT FOR SKY’s goal of introducing, promoting, and expanding domestically produced SAF.

The new company will be led by Yuki Nishimura (JGC Holdings, Sustainability Co-Creation Department), who also chairs the steering committee of ACT FOR SKY, and will work to realize Japan’s first commercial-scale domestic SAF supply system by fostering momentum for domestically produced SAF, and by changing the behavior of citizens and companies through changing their awareness of SAF.

Through the establishment of SAFFAIRE SKY ENERGY, the three companies will further accelerate business development aimed at building a SAF supply chain. We will be putting in place a system to supply domestically produced SAF in 2025, when worldwide interest in SDGs will be heightened by Expo 2025 in Osaka. The project is also part of efforts toward a sustainable circular economy.
