Paragraph starter

The research by Rojas Michaga et al. (2023) provides a comprehensive techno-economic and life cycle assessment of a Power-to-Liquid system for sustainable aviation fuel (SAF) production. Their findings indicate that an integrated system combining direct air capture, offshore wind power, and advanced refining can achieve a global warming potential of 21.43 gCO2eq/MJSAF, significantly below conventional jet fuel and meeting regulatory mandates. This demonstrates the potential for such integrated systems to decarbonize aviation, though economic viability is contingent on electricity costs and capital expenditure for capture technologies.
