Novel Framework for Actual Air Properties Correlations Used in Compressed Air Energy Storage for Saturated and Single Properties

Abstract

Compressed Air Energy Storage (CAES) is an economically viable technique that enables the storage of substantial amounts of electrical energy by utilising high-pressure air. Other energy storage technologies, such as flywheels and ultracapacitors, possess the capacity to offer services pertaining to power quality and stabilisation for short durations. However, they are not economically viable choices for load shifting and wind-generating assistance. Compressed Air Energy Storage CAES has recently gained much attention due to its comparable scale and cost to Pumped Hydropower Storage (PHS). Smaller CASE facilities also attract interest in more adaptable power system applications. The majority, if not all, of the existing literature on compressed air technology, relies on the assumption of ideal air qualities. However, there is a scarcity of studies that establish a direct correlation between the real properties of air and the performance of compressed air systems. This study presents novel correlation models for compressed air energy storage that incorporate real air parameters. Furthermore, this research study delves into the thermodynamic properties employed in Diabatic and Adiabatic processes, serving as a comprehensive resource for both theoretical understanding and practical application. The suggested correlations contribute to the advancement of knowledge on the underlying thermodynamic principles of Compressed Air Energy Storage (CAES). This research introduces a theoretical framework that aims to provide a comprehensive knowledge of the characteristics of Actual Air (AA) and highlights the significance of precise fluid property information in the computation and advancement of Compressed Air Energy Storage (CAES) techniques. This research examines the postulated correlations between the physical characteristics of air and the evaluation of cycle efficiency in Diabatic and Adiabatic processes.
