According to European non-governmental organisation Transport & Environment, for every 100kWh of renewable electricity, you get 77kWh of useable energy from a battery EV (BEV), but only 30kWh in a hydrogen-powered fuel-cell electric vehicle (FCEV). A green-hydrogen-powered EV therefore requires more than two-and-a-half times the amount of electricity as a BEV.
