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.
Couldn't that make Hydrogen as a bi-product of making nuclear power? That would make nuclear and hydrogen a natural? Power for the cars and nuclear power make electricity for our homes.
