Hunt also states that he is developing "other interesting gravity energy storage concepts," which should be published later in 2025. Source: IIASA A version of this article was originally published in 2023. A study shows that the shafts of abandoned mines could serve as energy-storing gravity batteries.
Scientists have developed a gravity battery that can store energy in abandoned mines. This innovative technology takes advantage of the millions of abandoned mines worldwide, with an estimated 550,000 in the U.S. alone, to store energy as potential energy.
Using abandoned mines for gravity batteries provides several benefits. It preserves jobs, hides unsightly infrastructure underground, and leverages existing connections to the grid. Additionally, these mines can be on standby to provide much needed energy for months or even years.
Turning abandoned mines into energy storage is one example of many solutions that exist around us, and we only need to change the way we deploy them," concludes Behnam Zakeri, study coauthor and a researcher in the IIASA Energy, Climate, and Environment Program.
Earlier this month, scientists revealed a gravity battery that takes advantage of vestiges of dirty energy’s past by using millions of abandoned mines worldwide (with an estimated 550,000 of them being in the U.S. alone) to store energy.
