This does not make any sense to me. Hydrogen is just a mean of energy transport. Someone has to make energy for you, whether it is electricity or hydrogen does not really matter. Roof solar battery is not enough to power your house alone, leave alone also powering a car.
One can produce hydrogen with electricity from renewable sources. Hell, with an extra fission reactor here and there one can produce jet fuel from seawater — something we'll have for the habitable future. Where and when one can throw money at a problem and get it right the first time, it's among the most satisfying victories one wll have that day. If one'd like to go off-grid and still run central air, money can do that.
