Batteries turn on and off quickly

  Because we all have enough batteries, right? You need enough batteries to provide hundreds of megawatts of quick power daily. See Figure E.2 https://www.oecd-nea.org/ndd/reports/2011/load-following-npp.pdf https://www.oecd-nea.org/ndd/reports/2011/load-following-npp...

    If batteries fill the need we can ramp up production of batteries. Lithium ion in the short term, and flow batteries or other utility scale batteries (Eg iron air), in the medium to long term. There are multiple utility scale competing battery technologies becoming quite mature and Thats a good thing. Especially if one or more of them are viable. It’s almost certainly easier and faster to scale battery tech than it has been nuclear.

      > If batteries fill the need we can ramp up production of batteries. No we can't. Not in the amounts required. We're not talking about 100kW Tesla batteries. > There are multiple utility scale competing battery technologies becoming quite mature You mean, there are multiple competing battery technologies that are barely at the theoretical level with multiple significant challenges and no implementations beyond theoretical or impractical for the use case in question. Flow batteries: low energy density, requires large tanks to be anywhere useful. Low charge and discharge rates, so are not practical for load following applications Iron-air: only theoretical so far with first small plant potentially in operation by 2023, and its efficiency is yet to be seen (so far it's mostly marketing materials and hype). > t’s almost certainly easier and faster to scale battery tech than it has been nuclear. Ah yes, it's certainly easier to scale non-existent and non-scalable tech.
