Energy Mine: Raising and lowering weights of hundreds of metric tons in a kilometer-deep abandoned mine shaft, as shown in this artist''s rendering, could store and deliver energy quickly
The proposed technology, called Underground Gravity Energy Storage (UGES), can discharge electricity by lowering large volumes of sand into an underground mine through the mine shaft.
The plant has a speed of 0.5 m/s and a power capacity of 30 MW. The lifetime of the power generation system is 20 years. The UGES energy storage system assumes 40,000,000 tons of sand with an average generation head of 1000 m. The plant''s storage capacity is 98 GWh, and the energy storage investment costs costs.
They claim that turning decommissioned mines into vast "gravity batteries" could provide up to 70 terawatts of energy storage. This is enough to match the entire world''s daily electricity
Indeed, this is the case for all energy storage devices – batteries, pumped hydro and so on – as there is always some loss of energy as it is converted between forms, according to Green Gravity Founder and CEO, Mark Swinnerton. "Energy storage technologies can see efficiency levels of 50–90% depending on their nature," says

Gravity energy storage systems, using weights lifted and lowered by electric winches to store energy, have great potential to deliver valuable energy storage services to enable this transformation. The technology has inherently long life with no cyclic degradation of performance making it suitable to support grids into the future and has be
Engineers are developing huge gravity batteries to store electricity, which could last longer than often-used lithium-ion storage, helping with the switch to renewable power. Gravitricity''s senior test and simulation engineer Jill Macpherson told Raconteur the test had been a success: "The demonstrator was rated at 250kW – enough to sustain
Based on the spatial resource endowment of abandoned mines'' upper and lower wells and the principle characteristics of the gravity energy storage system, an
Gravitricity has developed a unique energy storage system, known as GraviStore, which uses heavy weights – totalling up to 12 000 t – suspended in a deep shaft by cables attached to winches. This offers a viable alternative future to end of life mine shafts, which otherwise face costly infilling and mine decommissioning costs.

Understanding Gravity Energy Storage Technology. Gravity Energy Storage Technology, often reviated as GEST, operates on the principle of gravitational potential energy. It involves lifting heavy objects, such as massive weights or containers filled with materials, to a higher elevation when energy is abundant or inexpensive.
Swinnerton spent 25 years in global mining before founding Green Gravity, an Australian start-up that provides technology to store renewable energy using legacy mines. It works like this: heavy weights are suspended in a disused mine shaft. Lowering the weights winds a generator to create electricity. When supply of renewable power
