Startups scout mining sites to repurpose as large
Green Gravity and Wollongong Resources will work together to size and design gravity storage systems for eight decommissioned and inactive mine shafts in the region. The partners will also assess how repurposing as energy storage could be a path forward for coal mining operations as they are decommissioned.

Advantages and challenges in converting abandoned mines for energy storage
The main components of UGES are the shaft, motor and generator, upper and lower storage sites, and mining equipment. 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, according to IIASA. Energy storage in the long-term
Q&A: using digital twins to convert abandoned mines to clean energy
It works like this: heavy weights are suspended in a disused mine shaft. Lowering the weights winds a generator to create electricity. 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
Mine Shaft Thermal Energy Storage (Mstes) for District Heating
Abstract. This paper explores the feasibility and techno-economic performance of water-filled Mine Shafts as Thermal Energy Stores (MSTES) in supporting flexible operation of HP or CHP based district heating systems in a future wind based electricity grid.Literature on thermal energy storage and use of mines in district heating is reviewed and the use of
European Investment Bank supports thermal
Gravitricity''s energy storage solution works by raising weights in a deep shaft, with disused mine shafts currently being targeted by the firm, and releasing them when energy is required. Its proposed single weight full scale system could deliver up to 2MWh of energy storage, with future multi-weight systems having the potential for a
How abandoned mines can become clean energy storage systems
An international team of researchers has developed a novel way to store energy by transporting sand into abandoned underground mines. The new technique, called Underground Gravity Energy Storage
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, but they aren''t a silver bullet. That''s why companies like Gravitricity are exploring whether disused mines can solve the problem. Here''s Gravitricity''s Chris

Gravity energy storage with suspended weights for abandoned mine shafts
The total energy storage capacity of the 3234 mines analyzed (the shafts for which depth and diameter information is available) is 1.07 GWh. Of these, 340 of the mines have maximum energy storage capacities over 1 MWh, and range up to 6.7 MWh. Considering only these mines accounts for 0.804 GWh of energy storage (74.7% of the total).

The paper describes an energy storage system that uses compressed air and thermal energy storage, enabling installation in a post-exploitation mine shaft. The paper presents the concept and construction of thermal energy and compressed air hybrid storage system.
Novel energy storage technology involves suspending heavy weights
A novel energy storage technology, which involves suspending heavy weights above deep mine shafts, is a "serious contender" in the global energy storage market, its creators have said. Gravitricity told i its demonstrator project built in Edinburgh earlier this year has proved a success, with the team raising and lowering two 25-tonne
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.
