If you take $1 of electricity and water, you can convert it to $.50 of hydrogen bond energy, and then you can take the hydrogen run it through a fuel cell and get $.25 of electricity. It’s never going to be an alternative to battery chemistry which yields $.95 back.

Salt cavern storage doesn’t change the math.

Please read my other reply published nearby: we are not embarked into an efficiency race. Efficiency (of any renewable-source based system) is a mean, not an end.

"Total on- and offshore European hydrogen storage potential estimated at 84.8 PWhH2." is pretty significant and pertinent.
