Agreed we need hydroelectric pumped storage - what is a typical efficiency number for that? I'd think its super inefficient, but not sure what the numbers shoul

- karamanolev 4y ago> The round-trip energy efficiency of PSH varies between 70%–80%, with some sources claiming up to 87%. For me, that sounds like quite good, given the capacity possibilities. We can always build tiered storage, with smaller, but more efficient tiers (e.g. batteries) used first and PSH when that's filled up or exhausted.
- rr808 4y agoWow I actually was expecting more like 10-20%.
- karamanolev 4y agoTurbines and pumps can be surprisingly elegant and efficient when built well.
