Korean Researchers Create Sustainable Aviation Fuel from Wood and Grass

South Korea’s Korea Institute of Science and Technology (KIST) has developed a sustainable aviation fuel (SAF) derived from non-food plant materials, such as wood and grass, providing a renewable option that avoids competition with food resources. This innovative fuel aims to significantly reduce the aviation industry’s carbon emissions and address the sector’s environmental impact.

The SAF is produced through advanced chemical processes where plant oils are converted into energy-dense components like naphthenes and aromatics, essential for aviation. According to KIST, when blended with conventional jet fuel, this new SAF could potentially replace petroleum-based fuels.

Principal researcher Ha Jung-myung noted that the SAF has the potential to cut carbon emissions by up to 80% compared to traditional jet fuel. He also highlighted the advantage of using non-edible plants, which are more readily available than food-based materials, making large-scale production feasible. The research team has confirmed the fuel’s stability, running it continuously for over 100 hours, ensuring it’s ready for commercial application.
