刚刚，韩国发布，生物基SAF获支持！

Core Viewpoint - The article discusses South Korea's initiative to promote Sustainable Aviation Fuel (SAF) through a mandatory blending system, aiming for carbon neutrality in aviation and the establishment of a SAF alliance [3][4]. Group 1: SAF Blending Mandate - South Korea plans to implement a mandatory SAF blending ratio starting from 2027 at 1%, increasing to 3-5% by 2030, and 7-10% by 2035, with specific targets to be confirmed in 2026 and 2029 respectively [4]. - The government will support the development and investment in bio-based SAF through tax incentives, with facility investment support up to 25% and R&D support up to 40% [4]. Group 2: Global SAF Initiatives - Various countries have set their own SAF targets, including Japan aiming for a 10% replacement rate by 2030, Singapore targeting a 3-5% blending ratio by 2030, the UK planning to increase from 2% in 2025 to 22% by 2040, and the EU requiring a 2% blending ratio this year with a goal of 70% by 2050 [5]. Group 3: SAF Production Pathways - The article highlights the potential of non-grain alcohol-based SAF production pathways, particularly the Alcohol-to-Jet (AtJ) process, which is currently in the commercial pilot stage [6]. - Research focuses on efficiently constructing long carbon chain products from non-grain biomass, with significant advancements made by a team at Zhejiang University in developing a one-step ethanol to C3+ olefins technology, which reduces operational complexity and costs while achieving high yields [7].
