SK Energy Co., South Korea’s largest oil refiner, said on Sunday it has shipped its first batch of sustainable aviation fuel (SAF) to Europe, which imposes some of the strictest carbon neutrality regulations in the aviation industry.

With the shipment, SK Energy, a unit of the country’s top energy company and battery maker SK Innovation Co., has become Korea’s first oil refiner to export SAF to Europe.

SAF, produced from bio-based feedstock such as waste cooking oil and palm oil instead of fossil fuels, is generating interest as a next-generation eco-friendly energy source as it significantly reduces carbon emissions.

Amid ongoing global decarbonization initiatives, a growing number of countries are mandating the use of SAF blends, pointing to the SAF market's continued growth.

The European Union will require at least 2% SAF blending in aviation fuel starting in January, while Singapore plans to mandate a minimum of 1% SAF blending starting in 2026.

Korea is preparing to introduce SAF blending requirements in 2027.

CO-PROCESSING METHOD

In September 2024, SK Energy installed a co-processing production line and began commercial production of SAF.

Co-processing connects separate bio-raw material supply pipes to existing petroleum product lines to produce SAF and other low-carbon products such as bio-naphtha.

SAF mass production is expected to allow SK Energy to complete an entire SAF value chain, which includes raw material procurements, manufacturing and sales.

SK Innovation’s subsidiary SK On Trading International is engaged in the waste-based raw material procurement business while SK Energy produces and sells SAF.

SOARING SAF DEMAND

According to the International Air Transport Association (IATA), global demand for SAF is forecast to grow to 18.4 million tons by 2030 from 240,000 tons in 2022.

SK Energy is considering building a dedicated SAF production facility if demand is strong enough.

The company plans to supply SAF to Korean Air Lines Co. this year.

Korean Air, the country’s top airliner, began using SAF for international flights, starting with Korea-Japan routes in August.

“We plan to continue expanding SAF production and exports while closely monitoring domestic and international SAF policy changes and market demand situations,” said Lee Chun-gil, head of SK Energy's Ulsan CLX.
