The most difficult part is getting the water out of the air.
The electric power issue for the process is addressed by using an alternative means of electrical energy.

Wind power for an individual home has a very small footprint. Why does it have to be some huge corporate entity that provides wind power when a home wind turbine system would suffice?
Solar panels, wind turbines, hydrogen for heating/cooking purposes...all for free after the initial equipment purchase and installation...
Who can complain?
Well, I guess the utility companies can complain. There go the profits.
Large industries would probably still need large production facilities, but the average person/home owner wouldn't.
Same mass, I mean, not volume. As a result, gasoline and compressed hydrogen will deliver about the same energy per volume.
