Using abandoned or exhausted mines to store energy in this way gives a new life to the abandoned shafts and provides jobs in nearby communities, typically hit hard when a mine closes. The abandoned mines already have a lot of infrastructure built in, with safe mine construction and energy for elevators and other tools of mining.
This paper presents the first analysis of the technical potential of using gravity energy storage with suspended weights as a new technology for redeveloping abandoned deep mine shafts. Analysis is presented for sizing the suspended weight to maximize the energy storage capacity, given a mine shaft''s physical dimensions.

The work-energy theorem states that the net work done by all forces acting on a system equals its change in kinetic energy (KE). In equation form, this is: Wnet = 1 2mv2 − 1 2mv2 0 = ΔKE. If only conservative forces act, then Wnet = Wc, where W c is the total work done by all conservative forces. Thus, Wc = ΔKE.
The beauty of gravity batteries is that they simply involve lifting (charging) and lowering (discharging) a heavy weight, explains Simon Read writing for the World Economic Forum.
