The best energy storage we have is pumping hydro.

Pump water up a hill when power is cheap, let if flow downhill and spin a flywheel when production drops.

Huge battery banks with limited recharge cycles is stupid when all you need is some water and a high spot to put it.

Isn't that less efficient because of motor losses, drag, etc? It's also heavily dependent on geography.
