6 FAQs about [Price of adiabatic air energy storage power generation]

What is adiabatic compressed air energy storage?

RWE Power is working along with partners on the adiabatic compressed-air energy storage (CAES) project for electricity supply (ADELE). „Adiabatic“ here means: additional use of the compression heat to increase efficiency. When the air is compressed, the heat is not released into the surroundings: most of it is captured in a heat-storage facility.

Can adiabatic compressed air energy storage be used in a-CAES power plants?

The development of new technologies for large-scale electricity storage is a key element in future flexible electricity transmission systems. Electricity storage in adiabatic compressed air energy storage (A-CAES) power plants offers the prospect of making a substantial contribution to reach this goal.

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 .

How efficient is compressed air energy storage?

The system performance analysis and multi-objective optimization are carried out. Exergy efficiency and levelized cost of energy are 74.05% and 137.28 $/MWh. Compressed air energy storage technology is one of the key technologies for integrating renewable energy generation into the grid.

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).

How adiabatic energy is stored in a cavern?

In the adiabatic cycle described below the heat energy is extracted and stored separately before the compressed air enters the cavern (Fig. 1). When energy is required by the grid, the compressed air and heat energy are recombined, and expanded through an air turbine.
