Yes but the overhead we have is nothing compared to the energy needed to make everything hydrogen powered. we would need an absolute absurd amount of overhead to generate all the hydrogen from overhead alone.
It's kind of dumb to intentionally waste 75-80% of the total electric energy initially generated to power hydrogen vehicles.
Using hydrogen to store the occasional grid overhead to be used for the grid later is a great idea, it should absolutely be done ASAP...but it's not a solution to hydrogen powered vehicles.
A factory which only runs some of the time will be really expensive. From what I've seen it's way more cost effective to rely on batteries for surplus electricity.
So far grid scale battery storage only scales to stabilizing the grid. It’s better than anything else at that, but it’s not cost effective to for example power a town overnight until solar is back
