CAES stores energy by compressing air, providing large-scale storage solutions to help balance grid supply and demand.

How It Works

During low demand, excess energy compresses air in underground caverns. When needed, the air is released to drive turbines, generating electricity.

Benefits of CAES

It offers long-duration energy storage, can provide backup power for extended periods, and efficiently integrates with renewable energy sources.

Challenges & the Future

Efficiency varies based on system design and geological conditions. Research is focused on improving efficiency and expanding CAES to more locations.
