Supplying bio-jet fuel produced from microalgae to regular domestic flights

-June 18, 2021-

Press Release

IHI Corporation (Location: Koto-ku, Tokyo, President: Hiroshi Ide, hereafter “IHI”) IHI has now supplied bio-jet fuel produced from microalgae as a sustainable alternative aviation fuel (hereinafter referred to as "SAF" * 1 ) to regular domestic flights.
This fuel has developed by the commissioned business of the National Research and Development Corporation New Energy and Industrial Technology Development Organization * 2 (hereinafter "NEDO").
It conforms to the international standard "ASTM D7566 Annex 7" * 3  for bio-jet fuel, which was applied for and acquired by IHI in May 2020.


1.Overview
Among the global greenhouse gas reduction activities, ICAO (International Civil Aviation Organization of the United Nations), which is in charge of reducing CO2 emissions from the international aviation sector, has established targets to control the increase in CO2 emissions. The social implementation of technologies to reduce CO2 emissions related to air transportation, including the production of renewable alternative aviation fuels, is an urgent issue.

 IHI is working on a next-generation technology development of mass-production process of microalgae, Hyper-Growth Botryococcus Braunii (HGBb) * 4, and fuel manufacturing process of algal oil produced by the microalgae.

In the NEDO project, which started in fiscal 2017, we worked to establish integrated manufacturing technology from large-scale culture to SAF production using the facility in Kagoshima City, Kagoshima Prefecture, and the pilot outdoor culture facility in Saraburi Province, Thailand ,and acquired the approval of this bio-jet fuel in the international standard ASTM D7566 Annex 7.

Based on these results, we have supplied the SAF to regular flights departing from Tokyo International Airport (Haneda Airport, Ota-ku, Tokyo).
This is the first flight of an aircraft equipped with fuel based on the "ASTM D7566 Annex 7" .
