If they are going to use electrolysis to make hidrogen to be used in Fischer-Tropsch process, wouldn't it be cheaper to develop some engines which can run on hidrogen?
* There are dozens of aircraft models in use each of which would require significant design changes to run on hydrogen. It’s more practical to design one alternate jet fuel source.
* Hydrogen has worse energy density than jet fuel. Energy density is especially important for aircraft.
* hydrogen is a lot harder to handle than than jet fuel. It’s more corrosive, more flammable, needs to be kept under pressure or at cryogenic temperatures.
