This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.

Or water batteries for dams if your neighbors don't need your surplus, this way you don't need to extract lithium to produce regular batteries to store the surplus

Lithium isn't going to be the way to store electricity on the grid. I wish people would stop bringing it up.
There isn't going to be a single thing. Pumped hydro, flywheels, sodium-ion, flow batteries, and heating up sand all have a place.
