What? You don’t have Google? Options I know of (other than batteries and pumped hydro) : Compressed Air Energy Storage, Thermal Energy Storage, Fly wheels, Hydrogen, Supercapacitors, Gravitational Storage

The fact that you descend into complete science fiction should give you pause for thought. I doubt it will, but please think about how fantastical your proposed solutions are - “a massive lake of molten salt under every city” (I actually like that one!)…

- It’s not easy to go over all options.
- Many of these are largely theoretical, or for temporary storage. For instance, I don’t think fluwheels can store energy for months.
