Recent Advances on Alternative Aviation Fuels/Pathways: A Critical Review
نویسندگان
چکیده
The Paris Agreement’s objectives related to climate change put aviation under great pressure and environmental inspection. In particular, the industry is committed achieving a 50% reduction in CO2 emissions by 2050 compared 2005 levels. A shift alternative fuels seems imperative. International Air Transport Association (IATA) has identified production of drop-in sustainable liquid (SAFs) as most promising strategy, at least short term, reduce impact sector. Within this review, critical summary current fuels/pathways presented comparative analysis dominant technologies performed considering techno-economic assessment, evaluation, future projections. ‘ReFuelEU Aviation’ initiative on policies market incentives assessed. Hydroprocessed esters fatty acids (HEFA), Fischer–Tropsch (FT) synthesis, alcohol-to-jet (AtJ) conversion, e-fuel pathways are microscope. wide range potential fuel selling prices (0.81–5.00 EUR/L) was observed due presence multiple routes, while some seem able secure more than 90% emission savings fossil jet reference. accelerated scale-up SAF reasonable demand for industry. establishment framework alignment all involved stakeholders an immediate challenge.
