    We have used water before lithium, and it isn’t bad at all.

    Not so great in a flat dry desert though. Pump storage is great when there is lots of water and a naturally occurring elevation, but there’s lots of places on Earth that don’t have that, but do have energy to store.

          Middle-East involves plenty of mountainous areas, and the reason many of those are arid is because water, ahem, flows down.

          Also in a flat dry desert one can replace pumping water up with raising heavy things up. I think. More wear though.
