I remember reading a typically opinionated article on the The Register where the claim was made that pumped storage doesn't scale very well. Or rather, it scales fine, but your country will look very different when you've finished the necessary building work.
- Tuna-Fish 13y agoYeah, it can be very good, but there's a limit. There's a very interesting project in Finland to build a pumped storage facility that uses a 1400m deep abandoned gold mine as the storage location. The idea is to use a relatively small amount of water but at very high pressure provided by the depth of the mine -- the high potential difference makes generation more efficient and reduces capital costs. If this thing turns out to be profitable, this will probably be done to all sufficiently deep mine shafts and other deep enough holes.

- jlgreco 13y agoSo do the turbines/generators go at the bottom, in the mine, in this setup? That seems like it would have some interesting engineering challenges.
