Depending on different CAES systems and operations, storage capacity of air exergy in the cavern varies. In this section, taking the Huntorf CAES plant as a case study, exergy storage capacity of the compressed air in the cavern are evaluated in different operational scenarios and heat transfer conditions.
Thermodynamic responses of the compressed air in the cavern determine the total exergy capacity and power rating of the CAES system. This investigation considers two cavern operation modes of storing compressed air, including uncompensated isochoric air storage and compensated isobaric air storage.
Recently，great advances about the construction and operation of compressed air energy storage in hard rock caverns have been made by researchers around the world.
The value of the gas constant is 287.06 J/ (kg · K). In cavern-based CAES systems, the energy of the compressed air stored in the cavern increases when air is compressed and injected into the storage. Thus, parts of the exergy of the compressed air due to the increased pressure converted from electricity is stored in the cavern.
This paper presents a new method for calculating the total exergy of a predefined storage volume by tracking the air dynamics in the cavern, which can also be reversely used to estimate the cavern volume subject to a target exergy storage capacity.
The facility could potentially be used for CAES, so do other underground gas storage facilities in the UK. Thus the Hornsea is selected as a case study to initially assess the storage capacity of compressed air storage in the UK. Both cavern operational scenarios are considered in estimating the exergy storage capacity.
