3 FAQs about [Lebanon steam turbine compressed air energy storage]

What is compressed air energy storage (CAES)?

Compressed air energy storage (CAES) is practically the only proven technology capable of storing thousands of MW-hrs of the wind energy during off-peak hours, and distributing approximately 135% of the stored energy during peak hours.

How does a CT/cc plant increase power capacity?
