Could underground gravity energy storage repurpose old mines?

An international team of scientists recently proposed another innovative and resourceful solution that involves repurposing old mines: Underground Gravity Energy Storage (UGES). They outlined the idea in the journal Energies. UGES involves lowering large amounts of sand stored in containers attached to a central cable down a deep underground shaft.

How much would a deeper mine cost compared to a lithium-ion battery?

A deeper mine would not only produce and store more energy, but would also be more cost effective. Energy storage costs vary from $1 to $10 per kilowatt-hour for UGES, the authors calculate, downright cheap compared to lithium-ion batteries, which currently cost about $150/kWh. Battery prices continue to fall as chemistries improve, however.
