Is this hydrogen derived from splitting water, or from hydrocarbons? Often hydrogen is little more than a form of storage of energy obtained elsewhere. If that is the case here, then you would have something like: Hydrocarbons * efficiency producing electricity -> electrical energy * efficiency producing hydrogen -> hydrogen energy * efficiency in an ICE versus, for an electric car, Hydrocarbons * efficiency producing electricity -> electrical energy * battery efficiency -> battery energy * efficiency of the electric motor Eric
