I think my assumption with pumped hydro is that there must be something holding it back because it's been mature for a long time, so if it were as useful and scalable as you say, I think it would have been scaled a lot more by now.
- ncmncm 4y agoThe overwhelming majority of utility-scale storage today is pumped hydro. It stores and releases many GWh every day. You don't hear much about it because it just works.
- sanderjd 4y agoYes but is still a small amount of energy relative to total demand and there don't seem to be serious efforts to scale it up massively. I don't claim to know why there aren't. Maybe there should be. It just makes me suspicious when I see a mature technology that still sees limited deployment, that there is a good reason for that.
