The aviation industry has been studying strategies to produce sustainable aviation fuels (SAF) for over ten years. Our objective is to conduct detailed techno-economic analyses (TEA) of six SAF production technologies and to develop a simplified cost estimation method. Triglyceride based Hydroprocessed esters and fatty acids (HEFA) was compared against five lignocellulose-based technologies using standardized criteria. TEA was conducted to determine minimum fuel selling price (MFSP). The base case annual product capacity was fixed at 60 million liters of total fuel, for which SAF MFSPs ranged from 0.88 to 3.86 $ L⁻¹ of fuel. Triglyceride-based HEFA had the best economic performance. Although triglycerides are more expensive than lignocellulose, HEFA is still a very competitive technology due to its high fuel yield (86–91% of feedstock) and low MFSP. Lignocellulosic-based technologies have lower fuel yields (9–23% of feedstock) due to high oxygen content of initial feedstock, resulting in higher fuel cost per unit of fuel. In order to reach a market fuel price, SAF yields from lignocellulosic materials needs to achieve an estimated value of 60%. Such yields are only possible if carbon efficiencies are close to 100%. Therefore, efforts are needed to avoid the removal of oxygen as CO₂. Based on these considerations, a new scheme is proposed for SAF production that could result in yields near those needed to achieve cost targets. This proposed integrated biomass/natural gas hybridized concepts to produce inexpensive SAFs should be thoroughly investigated in future work.

十多年来，航空业一直在研究生产可持续航空燃料（SAF）的策略。我们的目标是对六种SAF生产技术进行详细的技术经济分析（TEA），并开发一种简化的成本估算方法。使用标准化标准，将基于甘油三酸酯的加氢处理的酯和脂肪酸（HEFA）与基于木质纤维素的五种技术进行了比较。进行了TEA以确定最低燃料销售价格（MFSP）。基本案例的年产品产能固定为6000万公升总燃料，SAF MFSP的范围从0.88至3.86 $ L ^-1燃料。基于甘油三酸酯的HEFA具有最佳的经济表现。尽管甘油三酸酯比木质纤维素更昂贵，但HEFA由于其高燃料产率（占原料的86-91％）和MFSP低而仍然是一项非常具有竞争力的技术。基于木质纤维素的技术具有较低的燃料收率（占原料的9-23％），这是因为初始原料中的氧含量较高，导致每单位燃料的燃料成本更高。为了达到市场燃料价格，木质纤维素材料的SAF产量需要达到60％的估计值。仅当碳效率接近100％时，此类产量才有可能。因此，需要努力避免除去作为CO ₂的氧气。基于这些考虑，提出了一种用于SAF生产的新方案，该方案可以使产量接近实现成本目标所需的产量。提议的集成生物质/天然气杂交概念以生产廉价的SAF的方法应在以后的工作中进行彻底研究。
