Energy efficient, yes. I was thinking about weight efficiency, though. That is, you can store a lot of energy in a gas tank that doesn't weigh a whole lot. Compress H2 or CNG to 3000 psi, and you need a heavy tank to store not nearly as much energy.

Likewise batteries: you might have a 99.9% efficient battery, but if one that holds the energy equivalent to a gallon of gas weighs several tons, it's not much practical use.

That's why everyone is using them.
Not the only reason. We also have a pretty good electric infrastructure. Fast chargers are a luxury item: many people could get by with a good extension cord.
