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?

The power capability of CT/CC plants is increased when the stored compressed and optionally heated (by the exhaust gas) air is injected into the existing engine at a location upstream of the combustors.

What PSIA does a gas turbine operate at?

A gas turbine (CT) operates at constant expander inlet pressure of 10 bar to 16 bar depending on model, while the Alabama CAES turboexpander operates at inlet pressures approximately from 800 psia to 1200 psia (54 bar to 82 bar). Standard “off-the-shelf” compressor may be used because of the lower operating flows and pressure.
