Are lithium-ion batteries used in underground mining machinery?

Provided by the Springer Nature SharedIt content-sharing initiative The use of lithium-ion batteries (LIBs)-operated underground mining machinery has gained tremendous momentum as a result of their numerous advantages. This

Can old coal mines be converted into gravity batteries?

Old coal mines can be converted into "gravity batteries" by retrofitting them with equipment that raises and lowers giant piles of sand. Underground Gravity Energy Storage system: A schematic of different system sections. ( Credit: JD Hunt et al., Energies, 2023)

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.

Are electric haul trucks a viable solution for the mining industry?

The incorporation of electric-powered haul trucks is a huge opportunity for the mining industry. Designing a solution that can integrate battery-powered equipment with existing mining processes, without disrupting current (non-stop) operations, will be critical to achieving emission reduction targets.
