favoritos Posted August 26, 2019 Share Posted August 26, 2019 Interesting idea. Wonder if the water already leaking into the mines would decrease the efficiency? There are some European projects that pump and store in hydro dams. They use wind and solar at their peaks to run the pumps. They release the hydro power when wind and solar decrease. Seems to be a similar idea. Use water as the storage device instead of batteries. The nice thing is the use of existing holes in the ground. We all know there are plenty of those in the UP. 1 Quote Link to comment Share on other sites More sharing options...

They do that in Ludington MI. They have some of the largest motors/generators in the world. 516,000 hp each. Quote Link to comment Share on other sites More sharing options...
