Australian start-up eyes disused mine shafts for giga-scale gravity

A newly launched Australian start-up has unveiled its own take on gravitational energy storage technology that will use super-heavy weights in legacy mine shafts to capture

Gravitricity: how mine shafts can generate electricity

To overcome this challenge, industry needs to find ways of storing surplus energy during particularly windy or sunny days. Traditional batteries are one way of storing energy, but they aren''t a silver bullet. That''s

Turning abandoned mines into batteries

A novel technique called Underground Gravity Energy Storage, developed by a team of researchers from the International Institute for Applied Systems Analysis (IIASA), turns decommissioned mines into long-term energy

UK startup eyes abandoned mine shafts for energy

Startup Gravitricity, which has just received a £650,000 grant from Innovate UK, plans to use abandoned shafts to house massive weights. When energy is plentiful, the weights will be winched towards the surface, in

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

Q&A: using digital twins to convert abandoned mines

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 Mine Shaft Energy Storage

The mine shaft, as a working mine and for energy storage, is subject to relevant regulations that need to be met. To confirm the assumptions about the possible use of the existing infrastructure, measurements of one

Gravitricity: how mine shafts can generate electricity | Interviews

To overcome this challenge, industry needs to find ways of storing surplus energy during particularly windy or sunny days. Traditional batteries are one way of storing energy,

6 FAQs about [Mine shaft energy storage Réunion]

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?

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.

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.

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).

Can a mineshaft be a useful service in the energy transition?

They may even have requirements to retain a mineshaft in place for many years beyond. So in that case, this is something that can provide a useful service in the energy transition as well as easing the financial headache for the owner of that mineshaft.
