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

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.
