Pumped storage hydropower (PSH) provides the largest form of energy storage in power grids, with 179 GW installed globally as of 2023.
Developing additional bulk energy storage, such as hydro pumped storage, could significantly improve grid reliability while reducing the need for construction of additional fossil-fueled generation capacity to support integration of wind and solar to the grid.

In this paper, a new type of pumped-storage power station with faster response speed, wider regulation range, and better stability is proposed. The operational flexible of the traditional pumped-storage power station can be improved
This paper presented and exemplified different types of pumped hydropower storage (PHS) plants, focusing on plants with large reservoirs for water and energy storage, the so called, seasonal pumped-hydro storage.
T-PSH technology is the fastest responding pumped hydro technology equipment available today for grid services. T-PSH efficiencies are competitive with lithium-ion (Li-ion) batteries, and T-PSH can provide increased storage capacity with minimal degradation during a 50-year lifetime.
Promising approaches include improving technologies such as compressed air energy storage and vanadium redox flow batteries to reduce capacity costs and enhance discharge efficiency.
The commissioning of numerous pumped storage hydropower projects, combined with the development of new energy storage technologies and advances in the grid network, are expected to significantly improve the overall situation.
