An aviation biofuel (also known as bio-jet fuel, bio-aviation fuel (BAF), semi-synthetic jet fuel, or sustainable aviation fuel (SAF)) is a biofuel used to power aircraft. The International Air Transport Association (IATA) considers it a key element in reducing the environmental impact of aviation. Aviation biofuel can be used to decarbonize otherwise hard-to-decarbonise medium and long-haul air travel via "drop-in-replacement" which does not require extensive modification to aircraft engine design. Synthetic paraffinic kerosene (SPK) refers to any non-petroleum-based hydrocarbon mixture designed as a blending component or complete replacement of kerosene jet fuel. Not all bio-fuels are produced in a sustainable manner. Typically sustainable aviation fuel is certified as being sustainable by a third-party organisation and may benefit from emissions trading or carbon-credit schemes depending on local laws. Biofuels are biomass-derived fuels from plants, animals, or waste; depending on which type of biomass is used, they could lower CO2 emissions by 20–98% compared to conventional jet fuel. The first test flight using blended biofuel was in 2008, and in 2011, blended fuels with 50% biofuels were allowed on commercial flights. In 2023 SAF production was 600 million liters, representing 0.2% of global jet fuel use. By 2024, SAF production was to increase to 1.3 billion liters (1 million tonnes), representing 0.3% of global jet fuel consumption and 11% of global renewable fuel production. This increase came as major US production facilities delayed their ramp-up until 2025, having initially been expected to reach 1.9 billion liters. Aviation biofuel can be produced from upgraded plant or animal sources such as Jatropha, algae, tallows, waste oils, palm oil, Babassu, and Camelina (bio-SPK); from solid biomass using pyrolysis processed with a Fischer–Tropsch process (FT-SPK); with an alcohol-to-jet (ATJ) process from waste fermentation; or from synthetic biology through a solar reactor. Pathways which use electricity-derived hydrogen as a feedstock are called Electrofuels or e-fuels. Small piston engines can be modified to burn ethanol as a replacement for aviation gasoline. SAF technology faces significant challenges due to feedstock constraints. The oils and fats used in production of hydrotreated esters and fatty acids (HEFA), crucial for SAF production, are in limited supply as demand increases. Although advanced e-fuels technology, which combines waste CO2 with clean hydrogen, presents a promising solution, it is still under development and comes with high costs. To overcome these issues, SAF developers are exploring more readily available feedstocks such as woody biomass and agricultural and municipal waste, aiming to produce lower-carbon jet fuel more sustainably and efficiently.
