📄 Abstract（原文）
Synthetic e-fuels derived from captured atmospheric CO₂ and green hydrogen represent a potentially carbon-neutral alternative to fossil fuels for the aviation sector, where electrification remains energy-density-constrained. This paper presents a rigorous quantitative investigation of e-kerosene production via the Power-to-Liquid (PtL) pathway, integrating: (i) full stoichiometric and thermodynamic derivations for PEM electrolysis, Direct Air Capture (DAC), and Fischer–Tropsch (FT) synthesis; (ii) Anderson–Schulz–Flory (ASF) product distribution modelling; (iii) a complete Python simulation computing fuel yield, life-cycle CO₂ emissions, and levelised production cost under six electricity supply scenarios; and (iv) Monte Carlo uncertainty quantification (n = 50,000 trials) and tornado sensitivity analysis. Results show that e-kerosene produced with wind or solar electricity yields net life-cycle emissions of 0.08–0.74 kg CO₂/L (mean 0.27 kg/L), an 88% reduction relative to conventional jet fuel (2.31 kg/L). With coal-based electricity, emissions exceed fossil baseline by more than 6×. Overall PtL energy efficiency is 42%, representing a hard thermodynamic ceiling. Levelised cost ranges from USD 1.35–4.50/L, falling to USD 0.85/L under 2035 optimistic projections. Six original quantitative conclusions are derived, including the identification of a critical electricity carbon intensity threshold (~200 g CO₂/kWh) below which e-kerosene is climate-beneficial, and the prioritisation of electrolyser efficiency as the dominant technical lever for both emissions and cost reduction.
