I'll be kindof surprised if this biofuel can provide the same amount of amount of energy as an equivalent amount of fossil fuel. I think the idea is more along the lines of research: You do not necessarily know what will work, so try many different things. Take what seems to work, and then allow them to play together! Each area takes a common standard, with built-in flexibility, and comes up with their local fuel variant that works best where they are, but can still play with vehicles made somewhere else. It may be a bit of a dream (or not), so you need research!
