“…The stated analysis observed a remarkable increase in the energy storage level and work output when the storage pressure is raised from 4 to 6 MPa. For further investigation, in another paper, Mozayeni et al 119 considered a cylindrical shape air storage vessel and studied the performance of the PH‐CAES system using multiphase VOF and turbulence k − ε models on the basis of dynamic flow and heat transfer in it. The measure data are analyzed and the result showed that in actual process stored energy level lies in between isothermal and isentropic processes 119 .…”

Intermittency characteristic of renewable energy sources can be resolved using an energy storage technology. The function of the energy storage system is to store the excess energy that is produced from various renewable energy sources during the off‐peak hours and releases the same energy during the peak hours. The energy that is produced from the renewable energy sources can be stored in different forms such as Mechanical, Electrical, Electrochemical, Thermal, Chemical energy etc. Among all these forms of stored energy, a CAES technology under the Mechanical form of energy is the most cost effective for the bulk energy storage purpose. It involves a combined operation of various components such as Compressor/Expander, Gas turbine, combustion chambers, heat exchangers, generator unit, and underground compressed air storage. This article focuses to review the detail of various CAES systems such as D‐CAES, A‐CAES, I‐CAES etc. Additionally, it presents various technologies that are used to improve the energy efficiency and applicability of the CAES system. It is found that a maximum RTE of the C‐CAES, A‐CAES, and I‐CAES are 54%, 71%, and 80%, respectively. In addition, the RTE of the modified CAES systems such as LP‐CAES, PH‐CAES, and SC‐CAES are about 90%, 80%, and 60 to 80%, respectively.

“…The simulations utilize the conjugate heat transfer approach to solve the heat transport in both the solid (aluminium plate) and the fluid (air and water). The Volume of Fluid (VOF) [28] technique is deployed to track the interface between the water and air at each time-step. The transport of the two-fluid phases is numerically represented by the scalar functions of phase volume fraction, α.…”

“…PHCA combines two compressed air and pumped hydro technologies, which overcomes many of their limitations. In addition, the PHCA can be more economical under similar conditions than the two mentioned systems due to its more accessible structure 26,27 .

Summary The purpose of this paper is to present a conceptual study of energy cycle performance consisting of two subsystems of electricity generation and storage. The introduced cycle is based on a linear Fresnel reflector (LFR) technology with a Stirling engine and thermoelectric generator (TG) to generate electricity and pumped‐hydro‐compressed air (PHCA) technology to store energy. Solar energy is converted into thermal energy through parabolic mirrors of the Fresnel and heating the fluid inside the collector. The resulting heat energy provides the required heat duty of the engine. This heat enters the Stirling cycle as input heat, and the mechanical energy convert into electricity. In addition, TG is thermally connected to the engine exhaust to generate additional electric energy. Then, the energy produced from the power generation subsystem is stored by the energy storage subsystem. Although many works had been done on the integrating of various solar thermal collectors and intermediate and/or downstream cycles, efforts had not been created to develop research on the combination of LFR, Stirling engine, TG, and PHCA system. Results showed that the power generation subsystem could generate 1.46 kW of electricity. The share of Stirling engine and TG in electricity generation was 72.6% and 27.4%, respectively. In addition, the power generation and energy storage efficiencies were 39.52% and 63.75%, respectively. Two different cases are offered for the design of the Fresnel solar field based on the useful power obtained.
