That's pretty neat! But it seems to me it's not storage because they're not putting energy in to get out later. It's more like mining naturally-occurring potential energy from the Earth's crust. Probably that potential energy formed millions of years ago when tectonic plate activity pushed the rock up to its present elevation. So - it's geothermal energy with extra steps.
