Flywheels can be deployed in grid applications where rapid fluctuations in power supply and demand occur, such as during peak load periods. Additionally, they contribute to frequency regulation and voltage stability, enhancing the reliability of power systems.

Pumped hydro storage (PHS) remains the most widely used form of large-scale energy storage globally. This method involves pumping water to a higher elevation when excess power is available, storing potential energy. During periods of high demand, the stored water is released to generate electricity through turbines. PHS installations can be extensive and are particularly suited for regions with significant elevation changes. Despite its advantages, PHS requires specific geographical features and long construction times, which limits its deployment in certain areas.

Thermal energy storage (TES) is another significant approach that manages excess thermal energy for later use. This technology often employs molten salts or chilled water in applications like concentrated solar power plants or district heating systems. By storing thermal energy, facilities can balance energy supply and demand efficiently, allowing for power generation during peak hours without additional fuel consumption. TES not only enhances operational efficiency but also contributes to reducing greenhouse gas emissions.
