SK Energy announced March 10 that it is set to become the first Korean refinery to supply a large quantity of sustainable aviation fuel (SAF) to a Hong Kong-based airline.

Following its successful SAF export to Europe in January, SK Energy said this achievement is expected to serve as a key steppingstone for the company to secure a leading position in the Asia-Pacific SAF market, a strategic region for Korean refiners.

SK Energy has signed a contract with Cathay, the home carrier of Hong Kong, to supply no less than 20,000 tons of SAF until 2027.

Since November, SK Energy has been supplying SAF certified by the International Sustainability and Carbon Certification System GmbH to Cathay at Incheon International Airport.

The two companies plan to gradually expand SAF usage to additional routes in the future.

The refiner said this agreement marks another milestone for SK Energy, as it secured a stable SAF supply contract with Hong Kong’s largest airline just two months after becoming the first Korean refinery to export SAF to Europe.

The Asia-Pacific region accounts for over 80 percent of SK Energy’s export volume, making it the company’s largest and most strategic market.

Hong Kong International Airport (Chek Lap Kok) ranked fifth globally in passenger numbers last year and serves as a key transit hub in the Asia-Pacific region.

Leveraging this strategic export to Hong Kong, SK Energy aims to accelerate its efforts to capture the SAF market in the Asia-Pacific region.

“Industry experts attribute SK Energy’s consecutive successes to its pioneering large-scale SAF production system among Korean refiners,” SK Energy stated.

Last September, SK Energy established a production capacity of 100,000 tons per year and began commercial production of SAF using the coprocessing method.

Coprocessing involves integrating biobased feedstock-supply systems into existing petroleum-processing lines, enabling the production of low-carbon products such as SAF and bionaphtha.

Global demand for SAF has been steadily increasing since the International Air Transport Association passed a resolution in 2021 to reduce the aviation industry’s carbon emissions by 50 percent compared to 2005 levels by 2050.

The European Union mandated that, starting this year, all flights departing from Europe must use a minimum of 2 percent SAF in their fuel mix.

This requirement will rise to 6 percent by 2030 and 70 percent by 2050.

Meanwhile, the U.S. has set a target replace all conventional jet fuel with SAF by 2050.

Also in the Asia-Pacific region, Singapore will implement its SAF levy with a 1 percent SAF-usage target in 2026 and South Korea will implement a 1 percent SAF-blending mandate in 2027.

According to market research firm Global Market Insight, the global SAF market is expected to grow at a compound annual growth rate (CAGR) of 46.2 percent—from approximately USD$1.7 billion in 2024 to USD$74.6 billion by 2034.

In South Korea, the Ministry of Land, Infrastructure and Transport announced in January that it would establish SAF-usage targets by the second half of this year in preparation for a mandatory SAF-blending requirement in 2027.

Last August, the Ministry of Trade, Industry and Energy and the Ministry of Land, Infrastructure and Transport announced that starting in 2027, the use of SAF blends would be mandatory for all international flights departing from South Korea.

“We will closely monitor changes in SAF policies and market dynamics both domestically and abroad,” said Lee Young-chul, the head of SK Energy’s marketing division. “By collaborating with Cathay Pacific and other partners, we aim to build a stable global SAF supply chain.”
