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.

      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.
