摘　　要：电子级可持续航煤(eSAF)是除传统生物质基可持续航煤(SAF)外,航空业实现碳减排的另一新兴方向,主要以可再生能源电解水所产绿氢为原料,结合可再生的二氧化碳(CO_(2)),通过费托合成(FT)路径、甲醇路径和直接合成路径,最终生成航煤馏分。从经济性角度看,eSAF的生产成本主要由绿氢成本决定,目前生产成本大致在人民币24元/L左右,高于传统化石航煤和生物航煤。目前eSAF仍面临多重挑战,包括原料可获得性、高生产成本、可持续性和地理空间匹配等问题。尽管短期内eSAF仍面临很多技术和经济上的挑战,但通过政策支持和技术进步可逐步提高其竞争力,实现对传统航煤的替代,为全球航空业实现碳中和目标提供有前景的途径。Electronic grade Sustainable Aviation Fuel(eSAF)is an emerging direction for the aviation industry to achieve carbon dioxide emission reduction,in addition to traditional biomass-based Sustainable Aviation Fuel(SAF).It primarily utilizes green hydrogen produced through renewable energy electrolyzing water,combined with renewable carbon dioxide.This combination undergoes processes such as Fischer-Tropsch synthesis(FT),methanol synthesis,and direct synthesis to ultimately produce aviation fuel fractions.From an economic perspective,the production cost of eSAF is mainly determined by the cost of green hydrogen,currently estimated at around RMB24 per liter,which is higher than traditional fossil aviation fuel and bio-based aviation fuel.At present,eSAF faces various challenges,including the availability of raw materials,high production cost,sustainability,and geographical matching.Although eSAF encounters several technical and economic challenges in a short term,gradual improvements in competitiveness can be achieved through policy support and technological advancement,paving the way for the potential replacement of traditional aviation fuels and contributing to the global aviation industry's carbon-neutral goals.
