Singapore Airlines to purchase sustainable aviation fuel from Aether Fuels

Singapore Airlines has signed an agreement to purchase up to 4,800 metric tons of next-generation sustainable aviation fuel (SAF) from Aether Beacon Pte Ltd. over a three-year period, with deliveries scheduled to begin in 2028.

The fuel will be produced at Project Beacon, a commercial production facility located at the Aster refining complex on Pulau Bukom in Singapore. This marks the airline’s first purchase of SAF produced via technology that converts waste-carbon feedstocks, such as biomethane and industrial waste gases, into liquid aviation fuel.

Unlike the more common hydroprocessed esters and fatty acids (HEFA) pathway, which relies on lipid-based feedstocks like oils and fats, Aether’s Aurora technology utilizes a modified Fischer-Tropsch process. The produced SAF will be certified under the Carbon Offsetting and Reduction Scheme for International Aviation. Aether aims to launch a larger commercial plant by 2031 with at least ten times the capacity of Project Beacon.
