“…The two existing CAES plants in Huntorf and Alabama are diabatic CAES (D-CAES), and also referred to as the first generation CAES. Second generation CAES include adiabatic CAES (A-CAES) [12] [13], [14], [15] [16], [17], [18], isothermal CAES (I-CAES) [19], [20], and hybrid CAES [21], [22]. In the D-CAES, the heat generated in the compression process is wasted and an external heat source is required in the expansion process.…”

“…Recently, it has been demonstrated that A-CAES concept can be modified in order to produce additionally heating and cooling energy, hence the trigenerative compressed air energy storage T-CAES has been introduced [6][7][8][9][10][11]. Many configurations has been proposed which differs on how the compression heat is used in the expansion.…”

Recently, major improvement on compressed air energy storage technology has been made by using the heat of compression for heating energy or using it to preheat the compressed air in the expansion phase and by demonstrating its ability to produce cooling energy. Thus, the trigenerative compressed air energy storage has been introduced. In this paper, we introduce a configuration of trigenerative compressed air energy storage system giving the preference to the electric energy production. The study then focuses on undertaking an optimization study via a parametric analysis considering the mutual effects of parameters. This analysis is applied to a micro-scale application including the existing technological aspects. The parametric study results applied on the hot temperature of the thermal energy storage indicate the possibility to find an optimal solution as a trade-off between system performances and other parameters reflecting its cost. On the contrary, the selection of the maximal storage pressure cannot be achieved by finding a compromise between energy density and system efficiency. A complete study of other design parameters will be addressed in a future publication.

“…Many configurations have been proposed, which differ according to the manner in which the heat of compression is used. Facci et al [6], Lv et al [7], Liu and Wang [8] and Arabkoohsar et al [34] devoted the heat produced during the charge phase for heating purposes while the electricity and the cooling energy are generated in the discharge phase. On the other hand, Jannelli et al [9], Li et al [10] and Han and Guo [35] suggested their configurations on the base of using an amount of heat stored during the expansion to increase the electrical efficiency while keeping the possibility to produce cooling and electrical energy.…”

“…The overall comprehensive efficiency achieved was high in winter months at 50% and lower in summer months at 30%. Arabkoohsar et al [34] demonstrated the potential of this system to support district heating and cooling and reserve services in electricity market for a typical large-scale application. The system was designed with different arrangement (series or parallel) of compressors and expanders.…”

In this paper, a trigenerative compressed air energy storage system is considered giving priority to the electric energy production with the objective to apply it at a micro-scale, typically a few kW. A whole detailed thermodynamic model of the system is developed including the existing technological aspects and the relations between components. The study then focuses on investigating the mutual effects of the design parameters and their influences on the system performances, energy density and heat exchanger footprints via a parametric study. From this analysis, it is found that the temperature of the thermal energy storage, the number of compression stages and the effectiveness of heat exchangers should be selected as a trade-off between the system efficiencies, heat exchangers footprints and the required number of expansion stages. Meanwhile, the selection of the maximum storage pressure is a choice whether to increase the energy density or the system efficiencies. An optimal design guideline of the above key parameters is then provided. This guideline, the method and the procedure presented in this paper can be applied to the optimization of the trigenerative compressed air energy storage and could be extended for the adiabatic one with minor changes. Based on existing technologies and using an optimal set of parameters, the round trip electrical efficiency of our system remains low at 17%, while the comprehensive efficiency reaches 27.2%. The poor performances are mainly linked to the exergy losses in the throttling valve and the low values of the component efficiencies at a micro-scale. The most optimization potentials are also addressed.
