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.

Hopefully you are free not to live there…
Pumped hydro?
Also very good, but geographically limited.
And very destructive for the local environment
