Unlocking the potential of geothermal mine water in Scotland

Going underground: Unlocking the potential of geothermal mine water in Scotland. Geothermal heat is a largely untapped resource globally, but its potential is starting to be realised in Scotland. Water in abandoned mines is opening up immense opportunities for reliable sources of heat and energy storage. November 30, 2023.

Pumped-storage hydroelectricity

Pumped-storage hydroelectricity ( PSH ), or pumped hydroelectric energy storage ( PHES ), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation.

Installation of a thermal energy storage site in an abandoned mine

As part of the new French law on energy transition, the Demosthene research project is studying the possibility of reusing old abandoned mines to store thermal energy in the Picardy region. The aim is to store the heat required for a small collective unit, which corresponds to a volume of water of 2000–8000 m3, depending on the

Lifecycle of Mine Water | SpringerLink

Former mining areas have the advantage that they already host underground cavities so these would not have to be excavated separately. The projects "Energy and Water Storage Harz (EWAZ)" and "Water Storage Harz 2050 (WSH2050)" present approaches for

Researchers found 37 mine sites in Australia that could be converted into renewable energy storage

Our new research identified more than 900 suitable locations around the world: at former and existing mining sites. Some 37 sites are in Australia. Huge open-cut mining pits would be turned into reservoirs to hold water for renewable energy storage. It would give the sites a new lease on life and help shore up the world''s low-emissions future.

UK Geoenergy Observatories

Caption: Mine water, commonly between 10 and 25°C, is pumped to the surface from boreholes. At the surface, heat pumps transfer and concentrate heat from the mine water, raising it to a temperature suitable for domestic or industrial applications (45–70°C). The water within this separate loop can be used to heat homes and offices.
