Paragraph starter
This research by Eyberg et al. (2024) provides a comprehensive techno-economic assessment of Power-to-Liquid (PtL) routes for sustainable aviation fuel (SAF) production, comparing Fischer-Tropsch (FT) and Methanol-to-Jet (MtJ) processes. The study highlights that process optimization, including the integration of reforming and recycling of gaseous products, can significantly enhance energy and carbon efficiencies, increasing them from approximately 30% to 40% and 60% to 90%, respectively. While both FT and MtJ routes are found to be comparably suitable for SAF synthesis, the research underscores the substantial cost premium of SAF over fossil jet fuel, even under optimistic future economic scenarios.
