Here is a link to just one group of well known industry players already producing e-fuel.

There are many others already constructing large plants to produce the same.

Also aware lots of research going on for producing Hydrogen without electrolysis by use of polymer membranes where Hydrogen produced just being in contact with a special membrane.

Anyway as always no silver bullet!

There will be a mix of fuels depending on vehicle or application.

Yes it is interesting, and the air and H2 to methanol step is very attractive to those without a rain forest... - Methanol and ethanol are a lot safer to store and ship by tanker than gaseous hydrogen and there are many countries (Brazil is the biggy) where cars already run on alcohol blends (up to E100 grade in Brazil, i.e. 100% alcohol ), currently almost as a waste product from fermenting sugar cane.
