Sustainable aviation fuels (SAF) are renewable or waste-derived aviation fuels. Currently, they provide the only viable replacement of traditional kerosene in the future for very large aircraft and very long distances. SAF are produced via a variety of paths and techniques, using different resources such as waste oils, agriculture residues, biomass, or waste. They can also be produced from nonfossil CO2, namely synthetic fuels or e-fuels. SAF have the advantage of being “drop-in fuels”; therefore, they do not require changes in aircraft, neither for the engines nor for the fuel tanks, and fuel infrastructure or airport facilities. The composition of the advanced biofuels is currently mostly paraffinic, and they are blended with conventional commercial and military jet fuel in variable amounts, depending on the fuel type; some biofuels have the addition of aromatics and lower blending percentages are needed. Moreover, since fuel plays also the role of lubricant, the effects of their use on joints and seals need to be considered. The evolution of aircraft engines as well as the fuselage design are a prerequisite to improve the compatibility with SAF, with the consequent reduction in blending percentages and addiction of aromatics.
