Advanced energy storage plant operation

What is advanced compressed air energy storage (a-CAES)?

A-CAES uses surplus electricity from the grid or renewable sources to run an air compressor.

Can compressed air energy storage improve the profitability of existing power plants?

Linden Svd, Patel M. New compressed air energy storage concept improves the profitability of existing simple cycle, combined cycle, wind energy, and landfill gas power plants.

Where was the first compressed air storage plant built?

However, in 1978 the world’s first compressed air storage plant (“CAES”) of 290MW capacity was built at Huntorf in Germany . In 1991 a 110MW plant was built in McIntosh, Alabama , and several other sites throughout the world are being considered for development.

What is compressed air energy storage?

Compressed air energy storage (CAES) is one of the many energy storage options that can store electric energy in the form of potential energy (compressed air) and can be deployed near central power plants or distribution centers. In response to demand, the stored energy can be discharged by expanding the stored air with a turboexpander generator.

How do adiabatic CAES plants reduce storage efficiency?

The storage efficiency of the diabatic CAES plants just described is reduced by cooling of the air before it enters the cavern, and by reheating the air prior to burning it with the fuel. In the adiabatic cycle described below the heat energy is extracted and stored separately before the compressed air enters the cavern (Fig. 1).

What is adiabatic air energy storage (CAES)?

This adiabatic CAES benefits from higher storage efficiencies and, notably, zero CO2 emissions and is being developed within the “AA-CAES” Project (Advanced Adiabatic – Compressed Air Energy Storage), funded by the European Commission under contract ENK6 CT-2002-00611, reference .
