Well we do that all the time at the moment, if it drops, prices increase, and your car sells power back (because you've got 300 miles in the battery but only need 30 tomorrow), green hydrogen halt production, bitcoin miners stop usage, grid level storage comes online

On the flip side when there's surplus that's used to make the hydrogen, to recharge the resovoirs, etc.

Many people feed back to the grid with their home solar etc, no difference to electric charging.

The problem is you can't plan for „this is rare“. Given how grid is getting more and more away from guaranteed sources, a once-in-few-years perfect storm may become a big event where shutting down hydrogen plants may be not enough to save the grid.

The other issue is, how much grid upgrades do you need to allow to keep it up from electric cars? Maybe even on green front it'd be better to have stable power generation with simplified grid. All those beefy substations don't come out of thin air.
