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

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