Are underground pumped storage power stations a viable post mining land use?Underground pumped storage power stations (UPSPS) is a form of beneficial post mining land use for closed underground coal mines. Its development potential is still largely unexplored in China. In this paper, a two-phase evaluation framework is developed for the site selection of UPSPS from regional to local scale. The main findings are as follows:.
Can underground pumped storage power stations convert coal mines into decentralized power supply systems?Underground Pumped Storage Power Stations (UPSPS) has the potential to convert underground coal mines into vital components of decentralized power supply systems.
Can abandoned coal mine goafs be used for hybrid pumped-hydro energy storage?Based on the reckoning of the existing coal mine goaf space in China, it has been found that developing hybrid pumped-hydro energy storage plants using abandoned coal mine goafs and operating them in daily regulation mode is feasible in the short term.
Is the Prosper Haniel mine a pumped storage power station?In Germany, the Prosper Haniel Mine is being converted into an underground pumped storage power station (200 MW, 750 MWh), using a ring structure of the mine (consisting of roadway and shaft) as an underground water storage structure (Fig. 3). The development of UPSPS remains at its infancy with few actual constructed engineering projects in China.
Is coal at a crossroads?In a world demanding sustainable and environmentally responsible solutions, coal, which has for many years a mainstay of power generation for many years, is at a crossroads. Coal mines, whether operating or abandoned, represent a legacy of the Industrial Revolution but also hold transformative potential.
Why are underground coal mines the most competitive option?Although there are several ways to develop this technology, the use of underground coal mines is the most competitive option for the following reasons: The larger the volume of the mine, the greater the energy storage capacity of the plant and the more efficiently it can adapt to nee
