2. TYPES OF ENERGY STORAGE TECHNOLOGIES

Various energy storage technologies are available, each with unique attributes and applications.

2.1. MECHANICAL ENERGY STORAGE

One of the oldest forms of energy storage involves mechanical systems, such as pumped hydroelectric storage and compressed air energy storage. Pumped hydro storage operates by transferring water between two reservoirs at different elevations. When there is excess electricity, water is pumped uphill, and during high demand, it is released to generate electricity as it flows back down. This method is widely deployed due to its high capacity, long duration, and efficiency.

Compressed air energy storage (CAES) similarly stores energy by compressing air in underground caverns or tanks. During periods of low demand, excess energy compresses air, which can be released later to drive turbines and generate power. While CAES systems face challenges related to infrastructure and geological requirements, their ability to provide large-scale energy storage and grid flexibility remains valuable.

2.2. CHEMICAL ENERGY STORAGE

Chemical energy storage systems, primarily in the form of batteries, have gained immense popularity over the past decade.
