Are the site selection requirements for energy storage stations high

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:

How does hydrogen energy storage affect site selection?

(4) Hydrogen energy storage is incorporated into the site selection consideration of wind-solar complementary power stations, and multiple factors such as resources, climate, economy and society are integrated, which significantly improves the scientific and reliability of site selection decisions.

Should hydrogen storage devices be integrated into the power to gas system?

In recent years, the innovative practice of integrating hydrogen storage devices into the power to gas system has attracted much attention, which not only helps to reduce the abandonment of wind and solar energy, but also improves the output stability of the power system.

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.

What is the energy storage capacity for a prospective upsps?

The energy storage capacity for a prospective UPSPS is dependent on the storage volume of the upper reservoir and the water head between upper and lower reservoirs, which is calculated from Eq. (4).

Which upper reservoir should be selected for a coal mine?

In cases where there is more than one suitable upper reservoir for a given coal mine, the one with the storage volume closest to that of the coal mine is selected (10 %). For an upper reservoir with several coal mines, the mine with the closest storage volume (10 %) should also be selected.
