How Coal Mines Could Be Turned Into Giant ''Batteries'' for Energy Storage

They estimate the global energy storage potential of UGES to be between 7 and 70 Terawatt-hours (1 Terawatt = 1,000 Gigawatts). To put that in perspective, it is equivalent to the energy stored in 87.5 to 875 million electric vehicle batteries. Just 56 Gigawatt-hours of energy storage was online globally at the end of 2021.

Energy storage in underground coal mines in NW Spain:

The mine water from abandoned coal mines can also be used for the development of Underground Pumped Storage Power (UPSH) or Compressed Air Energy Storage (CAES) plants [18–22]. Large amounts of stored water at stable temperature and low enthalpy are suitable for the supply of sustainable thermal energy in surrounding buildings.

Turning sand into energy storage

This devastates communities that rely only on the mine for their economic output. UGES would create a few vacancies as the mine would provide energy storage services after it stops operations." Exploring the options for energy storage at mines. Batteries and pumped-hydro storage (PHS) are the more common options for electrical storage.

Coal

Reuse and recycling can also reduce the environmental effects of coal production and use. Land that was previously used for coal mining can be reclaimed and used for airports, landfills, and golf courses. Waste products captured by scrubbers can be used to produce products such as cement and synthetic gypsum for wallboard.

Storing renewable energy in old mines

"Mines already have the basic infrastructure and are connected to the power grid, which significantly reduces the cost and facilitates the implementation of UGES plants." The peer-reviewed paper Underground Gravity Energy Storage: A Solution for Long-Term Energy Storage was published on Jan. 11, 2023 in the journal Energies.

Energy Storage

In Lake Macquarie, R&D work is being undertaken into the use of underground coal mine workings as a lower reservoir for pumped hydro energy storage (UPHES). The research aligns with one of the five foundational pillars of the NSW Electricity Infrastructure Roadmap - long duration storage.

Energy from closed mines: Underground energy storage and geo

An underground closed mine can be used to store energy for re-use and also for geothermal energy generation, providing competitive renewable energy with a low CO2 footprint. Jan Martin, 2013. "An Exploratory Economic Analysis of Underground Pumped-Storage Hydro Power Plants in Abandoned Coal Mines," FCN Working Papers 2/2013, E.ON Energy

How old coal mines could become new sources of clean energy

The potential lies in geothermal: heat generated by the Earth, which can be harnessed in a variety of ways. While in operation, underground coal mines are dewatered to allow for workers to extract coal. When a mine is not maintained, it naturally floods with surface and groundwater: which can be used for geothermal.
