国际航空运输协会：SAF的瓶颈在于技术而非原料供应

Core Insights - The International Air Transport Association (IATA) and Worley Consulting report indicates sufficient sustainable aviation fuel (SAF) feedstock is available to achieve net-zero carbon emissions in the aviation sector by 2050 [2][5] - The report identifies significant barriers to SAF production, including slow technological advancements and competition for biomass feedstock from other sectors [3][6] - By 2050, airlines will require 500 million tons of SAF to meet net-zero carbon emissions targets, with potential production from biomass exceeding 300 million tons annually [3][4][5] Feedstock Sources - Biomass is projected to produce over 300 million tons of bio-SAF annually by 2050, although this potential may be limited by competition for feedstock [4] - Power-to-Liquid (PtL) processes will need to contribute approximately 200 million tons of SAF annually by 2050, necessitating improvements in conversion efficiency and logistics [5] Challenges and Recommendations - Key challenges include strengthening the feedstock supply chain, accelerating technology deployment, and implementing coordinated government policies to support innovation and investment [6] - The report emphasizes the need for collaboration among governments, energy producers, investors, and the aviation industry to reduce investment risks and accelerate SAF commercialization [8] - Urgent action is required to transform the potential of SAF into reality, with only 25 years remaining to achieve these goals [8]
