“…Energy density E d (kWh/m 3 ) is defined by the amount of output energy provided per unit of volume as expressed by Eq. (30). This criterion is of crucial importance, as higher energy density requires a small volume which makes the system more compact and may reduce its cost.…”

“…In order to reduce the system losses, many researchers proposed innovative solutions. Houssainy et al [30] proposed a patented novel hybrid high temperature thermal energy storage and low temperature A-CAES including a turbocharger unit that provides supplementary mass flow rate which contribute to decrease the storage pressure/volume and reducing the system cost. Kim [31] carried out an energy and exergy analysis of different configurations of CAES with adiabatic or quasi-isothermal compression and expansions, constant volume and constant pressure air storage.…”

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.

“…In the A-CAES system, compression heat generated during the charge process is stored and reused to preheat air before expansion during the discharge process. Recently, Houssainy et al 20,21 developed a high-temperature hybrid CAES system by adding a high-temperature TES which was essentially an electric heater after the low-temperature TES to realize two stages of successive heating. Research about A-CAES has been active in recent decades.…”

Performance comparison of different combined heat and compressed air energy storage systems integrated with organic Rankine cycle

Summary Compressed air energy storage (CAES) is promising to enable large‐scale penetration of renewable energies (REs). However, conventional diabatic CAES (D‐CAES) depends largely on fossil fuels, while adiabatic CAES (A‐CAES) is limited in output power. To conquer these disadvantages, concept of combined heat and CAES (CH‐CAES) is proposed in this paper. The proposed system couples an electric heater with conventional A‐CAES. During charging, electricity storage transforms from pure compression to partly relying on Joule heating. The stored heat in an electric heater will be used to boost turbine inlet temperature during discharging. Consequently, system charge/discharge capacity can be improved without enlarging cavern size, raising cavern pressure, and producing greenhouse gases. This paper discusses three types of CH‐CAES systems with different electric heater installation positions. Off‐design performance analysis for each system is conducted on the basis of turbomachinery (compressors, turbines, and the pump) characteristic maps and heat exchangers off‐design models. Performance comparison is conducted between these three CH‐CAES systems (called Mode II, III, and IV for simplification) and the conventional A‐CAES system (Mode I). Control strategies are also given in this paper. Results show that the EVR (energy generated per unit volume of storage) increases with participation of an electric heater, while the RTE (system roundtrip efficiency) slightly decreases. Mode I has the highest RTE. The largest EVR appears in Mode III where the electrical heater is in series with the intercooler and after cooler. Mode II is a compromise solution to achieve both relatively high RET and EVR when the electrical heater is installed in series only with the intercooler. Mode IV with a paralleling electrical heater has great flexibility to adapt different user demands. The integration of the ORC has a positive effect on system RTE and EVR.

“…It is not casual that the most famous demonstration plant requires even MWhs of thermal energy to be supplied to the system to ensure high round-trip efficiency, i.e., between 63-74%, associated to CAES in a cavern of 120-m length and 4.9-m diameter [36]. Economics of CAES is not often faced by scientific literature unless hybrid-CAES architecture was studied in Houssainy et al [37], assuming the availability of natural cavern and remaining at a large scale. A scale of 150 MW to a lower size start to be promising in terms of investment cost for Ferretto et al [38], but only simulations were performed, and no actual coupling with the user was done.…”

Abstract:In the European Union (EU), where architectural heritage is significant, enhancing the energy performance of historical buildings is of great interest. Constraints such as the lack of space, especially within the historical centers and architectural peculiarities, make the application of technologies for renewable energy production and storage a challenging issue. This study presents a prototype system consisting of using the renewable energy from a photovoltaic (PV) array to compress air for a later expansion to produce electricity when needed. The PV-integrated small-scale compressed air energy storage system is designed to address the architectural constraints. It is located in the unoccupied basement of the building. An energy analysis was carried out for assessing the performance of the proposed system. The novelty of this study is to introduce experimental data of a CAES (compressed air energy storage) prototype that is suitable for dwelling applications as well as integration accounting for architectural constraints. The simulation, which was carried out for an average summer day, shows that the compression phase absorbs 32% of the PV energy excess in a vessel of 1.7 m 3 , and the expansion phase covers 21.9% of the dwelling energy demand. The electrical efficiency of a daily cycle is equal to 11.6%. If air is compressed at 225 bar instead of 30 bar, 96.0% of PV energy excess is stored in a volume of 0.25 m 3 , with a production of 1.273 kWh, which is 26.0% of the demand.
