What is Energy Storage and How Does it Work?

Energy storage refers to the technology that captures and holds energy for future use. It acts like a battery, allowing us to save excess energy generated during peak production times. This stored energy can then be released when demand is high or supply is low.

The most common method involves converting electrical energy into chemical, mechanical, or thermal forms. For example, batteries convert electricity into chemical potential. Pumped hydro storage uses gravity; water is pumped uphill to store energy and released through turbines when needed.

Advanced systems also include flywheels and compressed air storage. Flywheels spin at high speeds to retain kinetic energy, while compressed air systems store air under pressure in underground caverns. Each of these technologies contributes uniquely to maintaining a steady power supply amid fluctuating renewable resources.
