Hydrogen won't happen in passenger vehicles and it's too expensive to produce for it to be used for much else. Electricity is one of the fundamental forces. Using an element like hydrogen will never be as efficient. To beat electricity, you may be able to do it by controlling one of the other fundamental forces such as gravity.
