This isn't entirely correct even today, as there is equipment on the market now for producing, storing, and dispensing H2 at home in various quantities.
Consider a home with PV on the roof, a hydrolyzer and fuel cell in the back yard. The fuel cell is a combined heat and power unit for the house and possibly EV. The hydrolyzer and/or storage can feed the car. This type of system is in use in Japan, and has been in operation in New Jersey since 2006.
I'm not opposed to that; Hydrogen as an energy storage medium holds promise -- IF being used to store clean energy. My fear is that the "hydrogen economy" will be largely a way for petro companies to repackage their fossil fuels.
However, what is the capital outlay for a PV system, hydrolyzer, fuel cell, and H2 compression and storage, all sufficient to fuel a vehicle? I don't see this going mainstream quickly, even if it works well and deals with H2 generation losses, density and diffusion properties. It's far cry from plugging in an EV.
Motorists value convenience above all. That's the one strong suit of EVs that can overcome some of the trepidation and "range anxiety". Word of mouth about how convenient they really are to own and drive. I see H2 taking quite some time before it compares to the convenience level of EVs, or conversely the "drive anywhere at a moments notice" siren song of gasoline. Just doesn't seem to hit either note.
