Compared with axial compressors, the vortices inside centrifugal compressors are more intense and have a larger range of influence. The secondary flow inside the impeller can be summarized as the "jet–wake" pattern [17], which is also widely known as the two-zone model.], which is also widely known as the two-zone model.
How Does Compressed Air Energy Storage Work?
This energy storage system functions by utilizing electricity to compress air during off-peak hours, which is then stored in underground caverns. When energy demand is elevated during the peak hours, the stored compressed air is released, expanding and passing through a turbine to generate electricity.

Types of Biogas Storage Systems | BioEnergy Consult
The energy, safety, and scrubbing requirements of medium- and high-pressure storage systems make them costly and high-maintenance options for non-commercial use. Such extra costs can be best justified for biomethane or bio-CNG, which has a higher heat content and is therefore a more valuable fuel than biogas.
