Grid-level batteries and pumped hydro (which only requires a height differential, not a riverbed) have been a thing for quite a while now.

Grid-level batteries and pumped hydro (which only requires a height differential, not a riverbed) have been a thing for quite a while now.
- Ekaros 3y agoSo where exactly do you find the hundreds of square miles of space to fit pumped hydro to match this scale? Or even tens square miles with thousand meter drop height? And if that was so easy and cheap, why isn't it already build? Or grid level batteries storing 140 GWh for even intra-day storage...
- samus 3y agoAdmittedly pumped hydro can't be scaled up that much. However, the few places that are suitable are very well appreciated and likely won't ever be dismantled like these dams. For grid-level batteries, absolute space efficiency is not critical, so they allow a wider range of battery types to be used. Prices are rushing down. They are being deployed on such a massive scale that many new gas powerplant projects get cancelled.
