Imagine if the fuel could be sold as carbon negative. i.e They will (somehow) plant more trees or take the same amount of CO2 from air for every CO2 fuel you burn on top of the CO2 they collect back to make the synthetic fuel.
If some % of the fuel burned turns into some chemically stable carbon waste and 100% of the carbon in the fuel came from stuff that was grown recently then it would be carbon negative.
