Is it? Every house in my neighborhood has a 240V power line running to it, with 100A service typical.
There isn't a single hydrogen fuel station in my entire state.
Power delivery seems like basically a solved issue, Level 2 charging is attainable for practically all households with minimal personal investment; and Level 3 charging is mostly an investment in the physical stations to rectify AC to high voltage DC, the wires that carry the AC are already there.
