In the Great State of California most of the Hydrogen Refueling locations are at SHELL Oil Gas Stations. SHELL Oil does not use electrolysis to split water to generate their H. They do it by harvesting from Natural Gas. More electricity is used to create, compress, transport, and pump this hydrogen fuel than is generated by the fuel cell technology in the Fuel Cell Electric Vehicles themselves. It is far more efficient, at all levels, to simply use a battery instead. Using Hydrogen simply allows oil companies to keep vehicles tied to them as a future and everlasting revenue stream.
