Innovations in battery storage, such as advanced, grid-forming inverters, are allowing the mining industry to move away from diesel- and gas-powered generators.
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.
Can a mine run a solar power plant?
Some mine operators are already using their own land adjacent to mines to generate solar energy, which is then used to power mine operations. These mine-owned projects can then be scaled up and tied to the grid to sell excess power back to local communities.
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.
