8. If you are putting electricity in one end and out the other batteries are more efficient

Since you multiply efficiencies then any low number really hurts you, take my previous example where the overall electric in to motor shaft out was 55% and if you use a 97% efficient lithium battery then the overall efficiency is .9*.95*.97 = .83 or 83% so 17% loss versus 45% loss.

A bus is a decent example though of where hydrogen may make sense, it's a vehicle that runs all day and it's hard to make a battery that will drive that kind of load in that sort of duty, a commuting vehicle for a single person is different operating regime and batteries make a lot more sense.
