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

      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

              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!)…

                Given you’re making up things I never said I can only imagine what you’re respinding to? Where did a massive lake of molten salt under every city come from?

                  Sorry this is a late reply. I can see that mentioning molten salt was a bit left-field, However, it is one of the more realistic ways to store the huge amounts of power needed to fuel an economy for a couple of weeks (which you need in northern europe if you want to use solar/wind). Here’s a link about it:

                  https://onlinelibrary.wiley.com/doi/10.1002/cite.202000137

                  I am pro nuclear, but if we are going to descend into this renewable hell, then we need to actually think about how you store terawatt-hours of power. I really think that this kind of storage might be the nearest we have to a solution. we’ll only need it once we try to turn off the gas turbines, of course. It is fascinating that so many smart people don’t see that the whole jigsaw is missing vital pieces.

                    What might be the nearest solution to a nuclear reactor design they doesn’t go over budget, doesn’t get delayed decades, and doesn’t produce radioactive waste for which we don’t have a final storage solution anywhere* on the entire planet?

                    *I didn’t recently check if the storage in Finland is up an running yet.

              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.

                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.

                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.
