This versatility allows for customized solutions, matching the specific energy storage characteristics needed for various applications.

PUMPED HYDRO STORAGE

Pumped hydro storage involves the transfer of water between two elevations to store and generate energy. By utilizing excess electricity during low-demand periods to pump water to a higher elevation, energy can be stored and then released by allowing the water to flow back down through turbines during peak demand times.

This method is one of the most established forms of energy storage and boasts a capacity for vast amounts of energy storage. Pumped hydro is particularly suited for balancing day-night consumption patterns and offering a reliable means of grid stabilization, making it a favorable choice for regions where geographical conditions permit.
