2.2 MECHANICAL STORAGE

Mechanical energy storage technologies, particularly pumped hydro storage and flywheels, utilize kinetic and potential energy principles to store energy. Pumped hydro storage remains the most prevalent large-scale energy storage solution, leveraging gravity and water to create potential energy. Water is pumped to a higher elevation during periods of low demand and released through turbines to generate electricity when required.

On the other hand, flywheel energy storage systems store kinetic energy by spinning a rotor in a low-friction environment. The energy can be discharged quickly, making flywheels suitable for applications that require rapid response and high power output. Both mechanical storage technologies present distinct advantages in terms of efficiency and reliability, although geographic and infrastructural constraints may limit their widespread adoption.
