Understanding the mechanisms behind these systems is crucial for researchers to improve their performance and address existing limitations.

MECHANICAL ENERGY STORAGE

Mechanical energy storage includes technologies like pumped hydro storage and flywheels. Pumped hydro storage, one of the most established methods, utilizes large bodies of water. Water is pumped to a higher elevation during periods of low electricity demand and released back to generate electricity during peak demand. This system capitalizes on gravitational potential energy and offers significant storage capacity.

Flywheels, conversely, store energy in a rotating mass. Energy is stored when the flywheel is accelerated and released when it decelerates. This technology offers rapid response times and exceptional cycling capabilities. These mechanical systems are essential for grid stability and are increasingly being integrated into renewable energy projects to balance fluctuating energy supply and demand.

2. SIGNIFICANCE OF ENERGY STORAGE MATERIALS

The significance of energy storage materials transcends mere technological advancements; they represent a pathway towards a sustainable energy future.
