Is ethanol biofuel not an option? I imagine that actual production would be the limiting factor but it seems to me that should be a workable solution but would probably require significant retooling and redesigning of engines.

I'd guess we'll be looking at a combination of various fossil fuel replacements in the future. EV's are great, but it'll take up towards a century before combustion engines are a thing of the past.And I suspect that's being optimistic.
