> All true, but I still don't think hydrogen makes the leap. I wouldn't mind if it did, but the use cases won't stack well against some of the upcoming battery technologies.

That's a reasonable assessment, but as others have noted there're use cases that use hydrogen chemically rather than for energy (steel, fertilizer, etc.), so I expect significant hydrogen production for those.

Given that there will be significant hydrogen production, and given that hydrogen can be stored efficiently in the same salt caverns currently used for natural gas, I wouldn't be surprised to see hydrogen have some role in the power grid for seasonal storage.

Hydrogen for transportation is much more questionable; small-scale (cars) seems highly unlikely, but large-scale (container ships) might happen.
