Can a decommissioned mine be used as a 'gravity battery'?

According to the study, decommissioned mines could be repurposed to operate as "gravity batteries." The idea is simple: excess energy is used to lift heavy objects, like sand, up into the mine. When energy is needed again, the weight is dropped, spinning a turbine and converting the kinetic energy from gravity back into electricity.

Could repurposing abandoned mines save energy?

But the benefits of repurposing abandoned mines for energy storage don't stop there. The researchers also believe that operating gravity batteries in these mines could restore or preserve some of the jobs lost when the mines closed.
