Q&A: using digital twins to convert abandoned mines to clean energy
Our technology, described as gravitational energy storage, involves lifting heavy weights up a legacy mineshaft using excess renewables, and lowering the weights back down again at a later time. The scalability of the technology is significant with more than one million legacy mineshafts globally.
Breakthrough energy storage technology uses legacy mine
Green Gravity''s energy storage system moves multiple heavy weights vertically in a legacy mine shaft to capture and release the potential gravitational energy of the weights. By simply using proven mechanical parts and disused mine shafts, Green Gravity''s energy storage technology is low-cost, long-life and environmentally compelling.

6 FAQs about [Mine shaft energy storage Algeria]
How many coal mine shafts can be converted into gravity storage units?
Using data from the United Kingdom Government Coal Authority Abandoned Mine Catalogue, it has been estimated there are 340 mine shafts that could be converted into gravity storage units with energy capacities above 1 MWh, providing 0.804 GWh of energy storage.
Can gravity energy storage be used to redevelop abandoned mine shafts?
This paper has investigated gravity energy storage using suspended weights as a new technology for redeveloping abandoned deep mine shafts. It has been shown how to size of the suspended weight to maximize the energy storage capacity for a mine shaft, given its physical dimensions.
How many mine shafts have a potential energy storage capacity?
The maximum recorded depth for any of the shafts is 1040 m and the maximum recorded diameter is 7.55 m. Fig. 5. The number of mine shafts (for which depth and diameter information is available) with potential energy storage capacities above different levels. 340 mine shafts have a potential energy storage capacity above 1 MWh. Fig. 6.
Can suspended weights be used in disused mine shafts?
Suspended weights in disused mine shafts offers a new energy storage technology. Requires minimal land-use and can make use of existing excavations. Analysis is presented for sizing the weight to maximize the storage capacity. Decoupled power and energy capacity makes it suitable for high power applications.
What is the energy storage capacity of a mine?
From a maximum mass limit of 1000 tonnes to a limit of 10,000 tonnes, the total energy storage capacity increases from 0.48 GWh to 2.27 GWh. The relative share of the energy capacity which is provided by mine shafts with energy capacities above 1 MWh increases as the maximum mass increases, from 26.3% at 1000 tonnes, up to 89.3% at 10,000 tonnes.
How much energy does a mine shaft provide?
However, the relative share of the energy capacity which is provided by mine shafts with energy capacities above 1 MWh actually decreases slightly, from 76.9% at 3150 kg/m 3 (cement), to 73.1% at 8050 kg/m 3 (steel).
