I fought for a long time that ethanol and methonal up to some amount 30% or maybe 50% should have been made 'standard' fuel. For a long time a lot of natural gas was wasted that could have been turned into gas instead of blown into the atmosphere.
Granted electric cars made this less needed but before batteries as a technology broke threw, this was a great way to reduce emissions.
One of the issues is that fuel standard process were to slow, focused on only ethanol (in the US) and that car manufactures fought it.
But having a truly flexible fuel supply can do a lot for fuel prices and get them down. Specially after the natural gas boom in the US.
