Wang, Guo highlighted the use of corn, cassava, and corn cob as feedstocks. Future research should investigate the use of non-food biomass and waste materials to address food security concerns and broaden the array of usable feedstocks. It is showcased that the potential of FT fuels, especially when integrated with corn ethanol production. Continued research in techno-economic evaluation of innovative pathways and integration strategies is necessary . With study showing potential WTW GHG emissions reduction of at least 92% using electrofuels, it's evident that the future of aviation fuel might lean heavily on these innovations . More detailed studies into optimizing E-fuel production are warranted. A study focusing on PtL production highlighted its potential, especially for the aviation sector . Further research into the scale-up, optimization, and commercial viability of PtL processes is a promising direction. The study by hinted at the increasing competitiveness of the methanol production process in the mid-term future. Future research could delve deeper into market trends, economic feasibility, and cost structures. While GHG emissions remain central, the phenomenon of contrail-induced cloudiness, highlights the importance of addressing broader climate impacts. Further studies into the atmospheric and climate effects of different SAFs and their production processes are essential .
