2. PUMPED HYDRO STORAGE

A traditional method, pumped hydro storage, has proven its worth as a reliable and established technique for energy storage. This method involves two water reservoirs situated at different elevations. Energy is stored by pumping water from the lower reservoir to the upper one during periods of low demand or high production. When energy is needed, water flows back down, driving turbines to generate electricity.

Pumped hydro storage facilities are capable of providing large amounts of energy instantaneously. For instance, a typical facility can respond to energy demands within minutes, making it an essential component in stabilizing grids that incorporate intermittent renewable energy sources such as wind and solar. The ability to store energy in this manner encourages a more efficient use of resources and mitigates the challenges associated with renewable energy integration.

Companies like Duke Energy, Iberdrola, and EdF Energies Nouvelles are deeply involved in developing and maintaining pumped hydro storage solutions. They contribute to enhancing infrastructure and optimizing existing systems to increase overall efficiency and reduce operational costs. This approach not only bolsters the energy grid but also plays a significant part in meeting forthcoming energy demands sustainably.
