Molten salt storage would also pair well with high temperature nuclear. In particular MSR's, then the secondary or tertiary salt would be the stored salt. Pair with a 2-3x reactor capacity turbine and can load follow well. No worry about cloudy days or seasonal impacts. Moltex is planning on something like this. Keep the expensive reactor at full power all the time but still load follow, esp in a high renewables grid.

Are other flow battery chemistries also too early for this analysis? ESS and their iron flow battery look promising

Energy Vault is working on gravity storage, which -- I think it's comparable to the pumped hydro, but applicable anywhere. https://www.energyvault.com/

they're too early stage for my inclusion criterion; no announced grid scale projects yet. (though they do want to get there)

That's fair. Thank you for doing this series and all your writings, this is important stuff, needs to be more part of the discourse and get more attention. Cheers 💚 🥃
