You can use fuels made from renewables for this too, was just thinking about the near future. I'm somewhat pessimistic about large scale fossil fuel production ending in the world anytime soon. We'll have a long tail petering out period probably where the products get progressively more expensive, and if we avoid the mad max scenario, at some point get displaced by synthetic compatible fuels.
