Another advantage is the entire gasoline distribution industry can go away. Tens (hundreds?) of thousands of gas stations in the US alone, with their tanks leaking hazardous chemicals into our groundwater. Trucks and storage facilities in every town. Pipelines and tankers. Middlemen at many layers. Gone.

This is also one of the key strikes against hydrogen. Do you really want to build out an entirely new distribution infrastructure just to keep all those polluters in business?
