What are the advantages of compressed air storage?

Compressed air storage offers several benefits, including high energy density, quick response times, and low environmental impact.

Can you explain how it works?

Sure! Compressed air storage works by using excess energy to compress air, which is then stored in underground caverns or tanks. When energy is needed, the air is released to drive turbines and generate electricity.

What are its applications?

Applications include grid energy storage, peak shaving, and supporting renewable energy sources like wind and solar.

Are there any disadvantages?

Yes, some disadvantages include high initial costs, energy losses during compression and expansion, and the need for suitable geological formations.

How does it compare to other storage methods?

Compared to batteries, compressed air storage can store larger amounts of energy for longer periods, but it may be less efficient.
