Severe reductions in the greenhouse gas intensity of aviation fuels are required to get a growing aviation sector on a flightpath compliant with the Paris Climate Agreement. Introducing renewable energy into aviation is challenging. The power‐to‐liquid (PtL) pathway uses renewable electricity, CO2, and water to synthesize a sustainable alternative fuel that chemically resembles conventional jet fuel. The state‐of‐art of key technologies for PtL fuel production as well as the environmental and techno‐economic performance of the resulting fuel in comparison with fossil and biomass‐derived jet fuel are reviewed.
