Hydrogen is a big player in grid storage but Vanadium fuel cells, pumped hydro, more grid tie-ins all have a role.

As much as I’d like to believe hydrogen would be a great commuter car power plant, efficiency (and I mean well to wheel efficiency), safety of high pressure hydrogen, wear snd tear (mirai cars are not doing great after 6-7 years) need to be solved.

None of those alternatives have anything but a minor role. The overwhelming majority of grid energy storage will be from hydrogen energy storage:

All of the safety and wear and tear issues have been solved. This is really just fearmongering at this point.

As I said, I would love hydrogen to be mainstream. I can appreciate an argument that Elon musk has a whole “fool cell” army. I still don’t see the anti hydrogen conspiracy. I follow the space industry and can swine that similar challenges with hydrogen storage exist at 1 atm.

Toyota (and Japan) still haven’t done much H2 stuff for nearly a decade despite their awesome success with the Prius. Would love to be proven wrong.

You are already proven wrong. The biggest event in green energy is hydrogen right now. The only reason why people disagree at all is ignorance of recent events.
