Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential
Electrochemical energy storage (EES) technology plays a crucial role in facilitating the integration of renewable energy generation into the grid. Nevertheless, the diverse array of EES technologies, varying maturity levels, and wide-ranging application scenarios pose

Pumped hydroelectric storage is a mature technology that offers a long storage period, high efficiency, relatively low capital cost per unit of energy and fast response time. The typical rating is between 1000 and 3000 MW.
Due to the volatility of renewable energy resources (RES) and the lag of power grid construction, grid integration of large-scale RES will lead to the curtailment of wind and photovoltaic power. Pumped storage hydro (PSH) and electrochemical energy storage (EES), as common energy storage, have unique advantages in
Energy storage technologies available for large-scale applications can be divided into four types: mechanical, electrical, chemical, and electrochemical ( 3 ).
