Works in theory! Practice? That's something else
The 2020 ESGC report came out in December, the big winner is compressed air:
A peaker plant is currently around $175, so currently Hydrogen might be the big winner since caves aren't readily available and possibly housing unique inhabitants. Of course, could be any number of new tech break throughs changing things.
...The Department of Energy’s (DOE) Energy Storage Grand Challenge (ESGC) is a comprehensive program to accelerate the development, commercialization, and utilization of next-generation energy storage technologies and sustain American global leadership in energy storage....
