Indonesian airline uses palm oil produced SAF
The Garuda Indonesia Boeing 737-800NG aircraft flew from the capital Jakarta to Surakarta city about 550 kilometres (342 miles) away.
Garuda conducted several tests including a flight test on the new fuel earlier this month and an engine ground test in August.
The palm-oil blended jet fuel is produced by Indonesian state energy firm PT Pertamina at its Cilacap refinery, using hydroprocessed esters and fatty acid (HEFA) technology and is made of refined bleached deodorized palm kernel oil.
Pertamina has said the palm-based fuel emits less atmosphere warming greenhouse gases compared with fossil fuels, and palm oil producing countries have called for the edible oil to be included in feedstock for the production of sustainable aviation fuel (SAF).
Experts say the industry will need 450 billion litres of SAF a year by 2050, if the fuel is to account for around 65% of the mitigation needed to achieve net-zero targets.
But some countries have raised concerns over the potential for deforestation in the production of palm oil from plantations. The European Union has imposed import restrictions on the commodity.
In 2021, Indonesia ran a test flight with the same fuel on an aircraft made by state-owned Dirgantara Indonesia, flying from the city of Bandung in West Java to the capital Jakarta.
Indonesia has mandated 3% biofuel blending by 2020 for jet fuel, but implementation has been delayed.
