Is everyone tired of hearing about Fischer-Tropsch synthesis from me yet?
Too bad, here's some more from Boeing's
2022 sustainability report as well as the United Arab Emirates Ministry of Energy and Infrastructure's 2022
Power to Liquid Roadmap which was developed in consultation with Boeing. Please note that this is the freaking UAE. Oil & gas is their largest economic sector and they're an OPEC member, and even they are saying this is coming. The report also gets into some of the efforts occurring in other countries. This is not just a greenwashing propaganda publication; it's legitimate technical and economic feasibility analysis and is accurate, as far as I can tell.
Battery- and hydrogen-powered aviation technologies are in development, of course, but sustainable aviation fuel (SAF) will be of critical importance for two reasons:
1) There are thousands of kerosene-fueled jets in the global fleet that will remain operational for decades to come
2) Long-haul intercontinental flights will be unlikely to be viable with battery or H2 propulsion architectures for *at least* 20-30 years at present rates of improvement (even if we're optimistic about the progress of suitable batteries reaching let's say 500 Wh/kg energy density, it takes approximately a decade to design, certify, and ramp up production of a new large commercial aircraft design)
SAF will probably comes from many sources including biomass waste from other economic sectors, but that won't be sufficient to meet the overall need. A lot of SAF is planned to come from power-to-liquids (PtL) processes which are powered by renewables. That's where FT synthesis comes in, as Tesla noted in Master Plan Part 3.

This is going to drive a lot of demand for solar, wind and battery power (Tesla estimated 5 PWh/year of incremental electricity for SAF in the Master Plan) while also further contributing to accelerating the demise of the mine-and-burn oil economy. Jet fuel will be synthesized from nothing more than CO2, H20, and clean electricity.
