You repeat some of the anti-hydrogen memes. Hydrogen is actually quite storable, certainly much more easily stored than energy in batteries. The cost of underground storage caverns for hydrogen is two orders of magnitude cheaper than the cost of batteries storing the same energy.

That's great, but how do I take one of these underground caverns around with me? :P

More seriously, I'm sure hydrogen will make a valuable contribution to the stationary grid-level energy storage situation. I'm not convinced about other applications.

You don't, just as you don't take massive takes of compressed methane around with you (I know about CNG cars; they're not competitive with BEVs or liquid fueled cars.) Methane and hydrogen are competing in stationary applications.

Guess what the cost of an underground storage cavity is for natural gas? Very cheap, because they're everywhere.

Yes, but hydrogen has the advantage of not requiring CO2 to either be acquired or recovered.
