For several years, research work has been carried out on energy storage that uses changes in the potential energy of masses being lifted or lowered. The energy of such a solution depends on the mass to be transported and the height to which the weight has to be lifted. Increasing the weight to be lifted is limited by the parameters of the …
UPHES in old mines. Unlike conventional pumped storage projects, site selection for UPHES projects in old mines requires additional consideration of the geological and hydro-geological conditions of the mining area, which may even be decisive or restrictive. Tao et al. [27] proposed a hybrid multi-criteria decision-making framework to …

Turning abandoned mines into energy storage is one example of many solutions that exist around us, and we only need to change the way we deploy them," study co-author Behnam Zakeri said. A novel ...
One of such potential uses is the implementation of an underground pumped storage project using the existing infrastructure as a lower reservoir. There is a high energy potential of these sites since the available head can reach up to 1200m inside the shafts. This head is sufficient to operate the pump storage plant even with small or medium ...
