It marks the first investment by Japanese oil refiner Idemitsu Kosan in a SAF project outside Japan, and was supported by Jet Zero Australia's foundational investors, including Qantas and Airbus, Jet Zero said in a statement.
Qantas and Airbus last year said it would jointly invest A$2 million in the project. Both companies in 2022 set up a $200 million fund to help meet Qantas' goal of using at least 10% of SAF in its fuel mix by 2030 after the airline placed a multibillion-dollar order for Airbus planes.
The refinery, to be set up in the state of Queensland, will convert bioethanol from domestic agricultural by-products into sustainable fuels. It is expected to produce up to 102 million litres of SAF a year and 11 million litres of renewable diesel once operational.
SAF can be blended with conventional jet fuel and can reduce carbon emissions by up to about 80%.
