There are some projects that want to repurpose old mines for pumped storage.
- woodruffw 5y agoI'm curious how that would work, given that mines are usually below ground. Or do you mean mountaintop mines?
- cinntaile 5y agoIt works the same in both ways, you just need the height difference and two reservoirs. When you need the electricity, the water flows downstream into the mine reservoir. Then it gets pumped up again when it's cheap. I do wonder about the economic feasability, but maybe I'm underestimating the amount of empty volume available in a mine.
