I did a double take here, I believe you mean miles per gallon?

> We all know the answer (no way in hell). Hydrogen, bio fuels, efuels, etc. don't really stand any chance economically. None whatsoever. This is just greenwashing noise. None of that stuff is going to scale or matter.

Disagree, you seem to only be considering cars. All of these things are just different forms of energy storage and they are useful if battery technology doesn’t have multiple orders of magnitude of improvement left in it.

There are numerous high impact use cases where you need more density, faster energy transfer, and completely different weight profiles than batteries.
