在技术层面，SAF的多条技术路线正同步发展。根据相关标准，目前已有8条认证的技术路线，可利用 不同代际的生物基、废弃物或气体原料生产SAF。有业内人士认为，当前油脂加氢路线虽成熟，但原料 供应有限，未来需转向农林废弃物气化、废塑料热解及二氧化碳加氢等路径。 "SAF的成本是传统航煤的2至5倍，而对于像e-SAF这样的新技术，成本预计将是传统航空燃料的7至8 倍。"日前，国际航空运输协会能源转型总监Hemant Mistry在接受证券时报记者采访时介绍。 全球航空业正在致力于绿色突围，SAF（可持续航空燃料）作为减排主要可行技术路线，其被产业提升 到空前的重视程度。根据国际航协的预测，到2050年，SAF将承担航空业65%以上的减排贡献。不过如 何填平成本差距，也是摆在产业面前的难题。 原料供应不足是制约SAF产业规模化发展的重要瓶颈之一。目前，HEFA路线虽成熟，但原料供应有 限。有统计数据显示，中国拥有全球最大的废弃油脂资源，但产能仅满足全球千分之二的需求。 Mistry认为，SAF作为新兴产业必须得到技术研发推动、金融支持以及鼓励建立可持续供应链的政策支 持，才能打造新型能源市场。有必要尽快明确"难减排行 ...
