      Pumped hydro? Or one of the many other non battery storage options, or just over production

        Pumped hydro requires a specific sort of place and not sure there’s enough of them for most countries to rely on.

        How viable is pumped hydro? It would be good if feasible, but last I checked, there were not enough places where you can install them.

          No, you’re right. It’s not an option for everyone. Which is why I mentioned that there are many other solutions which are similar and over production which is simpler and cheaper

              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

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

                  Nobody wants energy stored for months. Whatever storage is used needs to get through temporary decreases in efficiency. In places that use solar, that means from one afternoon to the next morning. In places that use wind, it means until the wind picks up. We’re talking storage on the order of tens of hours at the most.

                  Are you proposing that the sun may not shine and the wind not blow anywhere at all for months?

                    Yeah, it is like that in some places. Also solar flux vary a lot by seasons as well. Dunno if wind has as much of an issue, but surely not great.

                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!)…
