“…In this scenario, while there is no energy loss to the environment, there is an exergy loss effect through a decrease in the stored energy potential [31]. The obtained and assumed parameters of the investigated materials are shown in Table 1 [32].…”

The paper presents the adiabatic installation of compressed gases energy storage. The authors present the results of analyzes for this type of installation due to the selection of thermal storage material. The simulations were carried out for basalt, granite and ceramics (alumina) as well as for porosity value from 0.375 to 0.39 of basalt-filled reservoirs in Thermal Energy Storage (TES) installation. Characteristics of outlet air temperature, air pressure drop amount of energy stored and external heat losses as a time functions during the charging phase are presented. The research indicated that due to the lowest density and average heat capacity of the materials studied, granite has the fastest and most intense physical exit loss from the storage tank which was approximately 1100 W. However, there was no significant effect on air pressure drop depending on the chosen accumulation materials. The effect of rock bed porosity on the pressure drop of flowing air was investigated. For a constant mass flow rate, pressure drop values ranging from 2200 Pa to 6200 Pa were obtained depending on the porosity value.

“…A simple preliminary sizing for a packed bed TES has been performed based on both thermal power (35 kWh) and discharge time (8 h) requirements. Basalts have been considered as filling material, its main thermo-physical properties have been taken from literature [6] and reported in Thus, a first stage sizing does not take into account the HTF mass flow rate through the system. Nonetheless, the thermal behavior of a cylindrical packed bed TES is clearly strongly influenced by the HTF mass flow rate.…”

The present work deals with the thermodynamic analysis of four different integration schemes for a packed bed thermal energy storage in a Stirling -CSP system. Simplified models for the different systems' configurations have been developed and analyzed in steady and transient working conditions. Particularly, a parallel and serial connection between the power and the storage unit have been compared, showing a trade-off between the contemporaneity of power production and storage and the usefulness of the storage itself accordingly to the working temperature constraints for the power unit. It is shown that a closed parallel system configuration is the most promising solution as it allows for a longer production during night time and an higher net energy production, it is therefore worth of further investigations.

“…At 20°C, flint rocks present thermal conductivities higher than that of rhyolite (2.3 W/m.K) [50]. At high temperatures, the analyzed flint samples show higher thermal conductivity values compared to HT ceramics (1.35 W/m.K at 350°C) and concrete (1 W/m.K at 200°C and 1.1 W/m.K at 332.5°C) [29,56,57]. In conclusion, the described rocks in this paper could be used in parabolic trough CSP plants which uses air as heat transfer fluid such as Ait-Baha pilot plant (3.9 MWth) in Morocco where the packed bed of rocks is used as thermal energy storage system [58].…”

“…In this regard, the most researches related to rock bed storage system focus only on modeling the thermocline system in order to predict the performance of the storage unit and evaluate its efficiency [25]. Few studies are interested in high temperature experimental characterization of physical and mechanical properties of rocks [25][26][27][28][29]. It is evident that the temperature plays an important role on the structural properties of rock [30,31], where some minerals contained in the rock can transit from phase to phase under the effect of heating, thus modifying the rock's properties [32].…”
