Electro-fuels can be produced from concentrated sources of carbon dioxide and hydrogen using electricity generated from renewable sources; this process enables energy storage at high volumetric energy density. Among the electro-fuels options, FT (Fischer-Tropsch) fuel is attractive for heavy-duty trucks and non-road transportation applications. The present study conducts a techno-economic analysis of FT liquid fuel production from H₂ and CO₂ using a detailed performance analysis. Minimum fuel selling price is estimated for a broad range of H₂ and CO₂ prices and for a range of potential CO₂ credits. The analysis indicates that H₂ price has the largest impact on the minimum selling price of FT fuel. FT fuel production with a CO₂ price of $17.3/metric ton requires an H₂ price of $0.8/kg to be cost-competitive with the pre-tax petroleum diesel price of $3.1/gal in 2050 (before the application of any CO₂ credits). When the H₂ price is $2.0/kg from central water electrolysis (2020 target), the minimum selling price of the FT fuel is $5.4–5.9/gal. A sensitivity analysis shows that future system optimization of FT fuel production could focus on improving the H₂ and CO₂ recycle contributions and FT fuel conversion ratio. The analysis results can be combined with various upstream systems for H₂ and CO₂ production.

可以使用可再生资源产生的电能，从二氧化碳和氢的集中来源生产电子燃料；该过程能够以高体积能量密度存储能量。在电子燃料选项中，FT（Fischer-Tropsch）燃料对重型卡车和非公路运输应用具有吸引力。本研究使用详细的性能分析对从H ₂和CO ₂生产FT液体燃料进行了技术经济分析。估计的最低燃料销售价格适用于各种H ₂和CO ₂价格以及一系列潜在的CO ₂信用额度。分析表明，H ₂价格对FT燃料的最低销售价格影响最大。FT燃料生产的CO ₂价格为$ 17.3 /公吨，要求H ₂价格为$ 0.8 / kg具有成本竞争力，而2050年的税前石油柴油价格为$ 3.1 / gal（在应用任何CO ₂信用额之前） ）。当来自中央水电解的H ₂价格为$ 2.0 / kg（2020年目标）时，FT燃料的最低销售价格为$ 5.4-5.9 / gal。敏感性分析表明，未来FT燃料生产的系统优化可能集中在提高H ₂和CO ₂再循环贡献以及FT燃料转化率上。分析结果可以与H _2的各种上游系统结合使用和CO ₂生产。
