Comment on First of its kind 'energy dome' storage project takes another step forward in Wisconsin

… what, just anywhere flat? Pumped hydro should be feasible wherever there’s a hill.
If we’re building big weird structures, even that is optional. You can put one pool above-ground and another in-ground. Deep and tall presumably beat wide.

To actually do the volumes that make pumped hydro practical you need not just a hill but a space which can hold a truly huge volume of water.

Yeah pumped hydro needs lakes, not pools, as far as I know. They flood entire mountain valleys, using the surrounding mountains themselves as the storage structure, because they need so much space.

But a warehouse-sized balloon works?

Yes, because phase transitions involve absolutely huge amounts of energy.
