Overview of Energy Storage Technologies

Energy storage stands as a cornerstone technology in modern electrical engineering, bridging the gap between energy generation and consumption. Unlike traditional systems that rely on instantaneous supply matching demand, storage allows us to decouple these processes. This capability is becoming increasingly vital as we integrate variable renewable sources like solar and wind power.

The fundamental purpose of energy storage is to capture energy produced at one time and release it later when needed. This provides flexibility, enhances grid stability, and enables new applications like electric vehicles and portable electronics. Without effective storage, managing intermittent power sources or providing backup power would be significantly more challenging.
