Sustainable Aviation Fuels (SAFs): Future Prospects and Challenges, Development and Production of Sustainable Aviation Fuels. Technological and Regulatory Challenges, Future Prospects for SAFs in Reducing Aviation Emissions
摘要
Sustainable Aviation Fuels (SAFs)Sustainable Aviation Fuels (SAFs), biofuelsBiofuel, are used instead of traditional jet fuel because they reduce aviation emissionsEmissions and have footprintFootprints of a lower carbon. Compared to kerosene, they can cut CO2 emissions by up to 65% because they are made from non-fossil resources. SAFsSustainable Aviation Fuels (SAFs) are essential to reaching the aviation sector’s 2050 net-zero goals. With a focus on feedstock flexibility and ASTM certification, this chapter examines manufacturing paths such as fatty acids (HEFA) and hydro-processed esters, power-to-liquid (PtL)Power-to-Liquid (PtL), and alcohol-to-jet (ATJ)Alcohol-to-Jet (ATJ) technologies. Regulatory obstacles like disjointed international policiesPolicies juxtapose technological difficulties like poor energy density and expensive manufacturing costs. Synthetic biology, algae-derived SAFsSustainable Aviation Fuels (SAFs), and catalytic process innovations are cited as game-changing innovations. Case studies, including Neste’s MY Sustainable Aviation FuelSustainable Aviation Fuels (SAFs), demonstrate scalability, while future prospects explore hydrogen-SAF hybrids and carbon pricing mechanisms. The chapter also underscores the need for cross-sector collaboration to overcome adoption barriers and align SAF production with global climate goals.
