"Michigan Technological University is studying whether communities could transform abandoned mines into valuable energy storage.
University researchers are partnering with the Marquette County city of Negaunee, population 4,500, on a pilot project that could help mining communities turn liabilities into assets. The prospect is particularly intriguing in the Upper Peninsula, home to hundreds of abandoned metal mines and cripplingly high electricity rates...."

Old and new will interconnect in an innovative way if researchers at Michigan Tech can pull off an energy storage concept that pairs some of the state’s abandoned and flooded mines with hydroelectric pumped storage...

What do hundreds of abandoned metal mines and high electricity rates have in common? Well, in Michigan’s Upper Peninsula, research is underway that could adapt the contours of underground mines to harness pumped hydro storage. Surplus power would pump groundwater, which tends to flood mines when they are abandoned, up an incline. When energy demands are higher, the water would drop down the mine shafts through turbines that churn out electricity....

We've gathered videos by KETL collaborators and others who are working on energy systems, justice, heritage, or related issues.
"With the rapid growth of renewable energy, the need for energy storage has been increasing at a neck-breaking speed. There are more than enough mines across the United States and the world that could potentially serve as sites for energy storage of different scales. More importantly, such facilities belong to the category of win-win projects as they are capable of delivering environmental, economic, and social benefits for the government, community, and industry, while achieving something that thus far has been out of reach: sustainable mining."
