Simply another convenient storage medium for electricity that requires 3X the input energy of batteries.
Distribution is a red herring (as you well know.) No distribution isn't a red herring. The large renewable resources are location dependent, so the power has to be transmitted somehow. If you want to transmit as electricity before manufacturing the hydrogen, then you are lowering the efficiency even further.
Hydrogen will not be refined, or pumped from wells. It can be produced anywhere there is electricity and water. With batteries you don't even need the water.
It can be produced at your corner filling station, or in your own garage, using electricity from your back yard solar panel; which brings up one of its advantages over batteries. Hydrogen can be produced at home while you're away, and conveniently stored for refilling your car when you return in the evening.
It can even be used to make solar power available 24 hours a day
You can do the same thing at home with batteries except you only need 1/3 the solar panels or any other energy source.
The bottom line is STILL that you need 200% more generating infrastructure if you are going to use H.
