This paper demonstrates a new method by which the energy storage density of compressed air systems is increased by 56.8% by changing the composition of the compressed gas to include a condensable component. A higher storage density of 7.33 MJ/m3 is possible using a mixture of 88% CO2 and 12% N2 compared to 4.67 MJ/m3 using pure N2. This ratio …
The composition of the gas in compressed air storage is a key parameter in maximizing the energy density. A second key aspect is that one of the gaseous components should be condensable at some stage in the compression process. To increase the energy density of GLIDES, air is substituted with a mixture of carbon dioxide and nitrogen.
The proposed compressed gas energy storage system will produce electricity upon withdrawal of the high-pressure gas that was previously injected by the electric-drive compressors. The CGES system also includes an aero-derivative gas turbine for a nameplate rating of 35 MWe with a primary energy efficiency of 42.4 percent.
The storage volume for a compressed gas can be calculated by using Boyle's Law pa Va = pc Vc = constant (1) where pa = atmospheric pressure (14.7 psia, 101.325 kPa ) Va = volume of the gas at atmospheric pressure (cubic feet, m3 ) pc = pressure after compression (psi, kPa ) Vc = volume of gas after compression (cubic feet, m3 )
Compressed air energy storage (CAES) is an effective solution for balancing this mismatch and therefore is suitable for use in future electrical systems to achieve a high penetration of renewable energy generation.
When a gas is compressed, it stores energy. If an uncontrolled energy release occurs, it may cause injury or damage. Stored energies in excess of 100 kJ are considered highly hazardous. Sometimes it is helpful to think of stored energy in terms of grams of TNT. One gram of TNT contains 4.62 kJ of energy.

Optimal and effective storage of compressed air energy (CAE) is consistent with the energy efficiency recommendations of the Energy Efficiency Directive (EED) [1]. The European Union (EU) has made energy efficiency a priority and legal obligation, requiring member states to reduce energy consumption by 9% by 2030 compared to 2020 levels.
