Hydrogen/Hindenburg. Great neighborhood storage. Put it in Lakehurst, NJ.

Things have come quite some time since then.

There have been some remarkable achievements in H2 powered vehicles going back 30+ years. However, the economics were never there. Perhaps now they are.

Consider this...the utilities utilize the spining reserve to generate H2 at night. It would not be free energy, but more a recovery of wasted energy.

This is liquid hydrogen(super cooled) not gaseous as in the Hindenburg. It's vaporized and delivered to the engine under very low pressurization. BMW is also testing a car that runs on gasoline or hydrogen. It has two fuel tanks and if you can't find a hydrogen station to fill-up you can switch to gasoline. This car has been tested under very vigorous crash conditions and they reported no ‘atomic bomb’ explosions from the liquid hydrogen so you need not worry about a car bomb if you crash into one of them. Honda has conducted similar tests. My question I can't get an answer to is how much does hydrogen cost per gallon? If it cost more than gasoline than why convert? The mileage in the BMW is significantly less when using hydrogen over gasoline.
