“…As shown in Figure 4, a gas turbine plant, using air and gas as the working medium, mainly consists of three sections: gas turbine, compressor and combustor. Gas with high temperature and high pressure, which is formed by mixing compressed air and fuel in the combustion chamber, drives the turbine which in turn drives a generator to generate electricity [20,21]. For a CAES plant, as shown in Figure 5, there are two different stages of operation, namely compression and expansion.…”

With the increase of power generation from renewable energy sources and due to their intermittent nature, the power grid is facing the great challenge in maintaining the power network stability and reliability. To address the challenge, one of the options is to detach the power generation from consumption via energy storage. The intention of this paper is to give an overview of the current technology developments in compressed air energy storage (CAES) and the future direction of the technology development in this area. Compared with other energy storage technologies, CAES is proven to be a clean and sustainable type of energy storage with the unique features of high capacity and long-duration of the storage. Its scale and cost are similar to pumped hydroelectric storage (PHS), thus CAES has attracted much attention in recent years while further development for PHS is restricted by the availability of suitable geological locations. The paper presents the state-of-the-art of current CAES technology development, analyses the major technological barriers/weaknesses and proposes suggestions for future technology development. This paper should provide a useful reference for CAES technology research and development strategy.

“…At present, pumped hydroelectric energy storage (PHES) and compressed air energy storage (CAES) are two energy storage technologies suitable for large-scale energy storage applications [4,5]. Compared with PHES, CAES has the advantages of low investment costs, fast construction time and high economic feasibility.…”

“…Ibrahim et al [18] presented a hybrid wind-diesel CAES to heighten diesel power output, increase engine lifetime and reduce the fuel consumption and greenhouse gas emissions. Yao et al [5] proposed a novel combined cooling, heating and power system (CCHP) combined with CAES and a gas engine; the system increases the output power of the CCHP system and realizes energy cascade utilization. Nielsen et al [19] and Basbous et al [20] exposed new CAES systems based on diesel engines, which can be applied to remote areas and ships.…”

“…Thus, developing a small-scale CAES system, which could use an artificial air vessel instead of a natural cavern to store compressed air, has become the main trend in recent years [5]. Because of the advantages of the gas engine in the small-scale industrial system, integrating the gas engine with CAES could not only boost the system output power, but also improve the efficiency of energy utilization and operation flexibility in the system [5]. Ibrahim et al [18] presented a hybrid wind-diesel CAES to heighten diesel power output, increase engine lifetime and reduce the fuel consumption and greenhouse gas emissions.…”

Abstract:The compressed air energy storage (CAES) system, considered as one method for peaking shaving and load-levelling of the electricity system, has excellent characteristics of energy storage and utilization. However, due to the waste heat existing in compressed air during the charge stage and exhaust gas during the discharge stage, the efficient operation of the conventional CAES system has been greatly restricted. The Kalina cycle (KC) and organic Rankine cycle (ORC) have been proven to be two worthwhile technologies to fulfill the different residual heat recovery for energy systems. To capture and reuse the waste heat from the CAES system, two systems (the CAES system combined with KC and ORC, respectively) are proposed in this paper. The sensitivity analysis shows the effect of the compression ratio and the temperature of the exhaust on the system performance: the KC-CAES system can achieve more efficient operation than the ORC-CAES system under the same temperature of exhaust gas; meanwhile, the larger compression ratio can lead to the higher efficiency for the KC-CAES system than that of ORC-CAES with the constant temperature of the exhaust gas. In addition, the evolutionary multi-objective algorithm is conducted between the thermodynamic and economic performances to find the optimal parameters of the two systems. The optimum results indicate that the solutions with an exergy efficiency of around 59.74% and 53.56% are promising for KC-CAES and ORC-CAES system practical designs, respectively.
