Yeah, I think massive chemical batteries for storing excess electricity to facilitate a contrived green energy market is a bad idea.

      LIthium Iron Phosphate is cheapest relatively dense battery type. Sodium ion will be if lithium get expensive.

        You can draw an arbitrary line of density you find good enough. But with how much space us wasted in some countries, that line should vary a bit place to place

      Weirdly it’s not, except maybe gravity batteries where nice reservoirs happen to exist already. It should be but it’s not right now.

      Li-ion has economy of scale right now. I do think molten metal etc will overtake eventually, but they’re currently playing catchup and li-ion has dropped in price so much over time that it’s surprisingly cheap even where it should make no sense.

        soooo, dams?

          Dams are a normally a power supply rather than a battery. I was more thinking pumped storage hydro. Which is usually done where theres 2 lakes next to each other at very different heights, so you can “store” power by pumping water up and release by pumping back down.
