energy storage systems using end-of-life mine shafts

By repurposing disused mine shafts for energy storage, mine shafts can fill a productive function for up to 50 years beyond their original lifetime, and can mitigate decommissioning costs, while simultaneously creating new job opportunities and contributing to the green energy transition.

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.

Storing renewable energy in mineshaft weights may be cheaper

Up to 24 weights totalling 12,000 tonnes can be stacked in a mine shaft to capture power and can then be released "with sub-second response time". "The climate emergency means we need to find new ways to capture and store green energy so we can use it when we need it," Blair added.

6 FAQs about [Mine shaft energy storage Brunei]

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 coal mine shafts can be converted into gravity storage units?

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.

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).

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 does a sand mine affect energy storage capacity?

The deeper and broader the mineshaft, the more power can be extracted from the plant, and the larger the mine, the higher the plant's energy storage capacity, as per the release. Since the energy storage medium of UGES is sand, there is zero energy lost to self-discharge, unlike normal batteries.
