Mine pumped water storage

Are underground pumped storage power plants a viable solution?

Therefore, Underground Pumped Storage Power Plants (UPSP), as first introduced in the early 20th century by Fessenden , offer a viable solution that capitalizes on the utilization of abandoned underground spaces and effectively circumvents topographical constraints and limitations associated with surface footprint [5, 12].

Are pumped storage reservoirs enclosed underground?

The reservoirs are enclosed underground, so this is referred to as “enclosed” PSAM, as shown in Fig. 7 (b). The China Energy Investment has built underground reservoirs in the goafs of multiple mines in the Shendong mining area , which provides a reference for the construction of all-underground pumped storage reservoirs.

Does China energy investment build underground pumped storage reservoirs?

The China Energy Investment has built underground reservoirs in the goafs of multiple mines in the Shendong mining area , which provides a reference for the construction of all-underground pumped storage reservoirs. The “closed” PASM has very little evaporation and no requirements on the surface area.

When was underground pumped storage developed?

In 1969, Sorensen considered the development of underground pumped storage to be promising. Around the same time, several Swedish engineers proposed developing underground cavern-based lower reservoirs to complement surface reservoirs for pumped storage .

Are pumped storage and abandoned mines a good investment in China?

A detailed review of China's latest developments in PSPPs is provided. The combination of pumped storage and abandoned mine demonstrates considerable social and environmental economic benefits. A case study of Panyi mine for developing PSAM in China are presented.

Can pumped storage and abandoned mines be used in PSPP models?

According to a summary of the PSPP models using abandoned mines, the application of PSAM is analyzed, and the combination of pumped storage and abandoned mine demonstrates considerable social and environmental benefits. 1. Introduction
