“…However, the inherent nature of renewable energy, i.e., randomness and intermittence, has greatly restricted the large-scale utilization of renewable energies, mostly in the power grid [1,2]. Energy storage technology can deal with the encountered situation by storing the excess renewable energies and releasing the energy to balance the difference between energy demand and supply [3].…”

“…Grazzini and Milazzo [9] presented a thermodynamic analysis for an adiabatic compressed air energy storage system (ACAES) and proposed the variable configuration system with a variable compression ratio to address the un-steady operation of the components. Wolf and Budt [1] introduced a low-temperature adiabatic compressed air energy storage (LTA-CAES) plant, which can avoid all of the technical challenges of adiabatic CAES designs. Arabkoohsar et al [10][11][12] proposed a CAES system equipped with an ancillary solar heating system for a large-scale PV farm in Brazil, and the thermodynamic and economic analyses are conducted to select the best operation strategy of the power plant.…”

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.

“…In such a concept, the heat absorbed by the intercoolers during the compression phase is stored in a thermal energy storage (TES) system and utilized during the discharge phase to heat the pressurized air. A-CAES systems can be classified into high temperature (400-800 • C) [3,4] and low temperature (80-200 • C) systems [5]. High temperature systems call for innovative compressors capable of operating at very high discharge temperatures.…”

Abstract:In the present paper, the performance of an energy storage concept based on the integration of a compressed air energy storage (CAES) system into a gas-steam combined cycle (GSCC) plant is investigated. CAES systems featured by different design specifications have been coupled with a commercially available small size GSCC plant. Storage efficiencies up to 65% have been evaluated for CAES design power output ranging from 5 to 10 MW. A techno-economic analysis aimed at assessing plant performance and investment costs has been performed. Despite the relatively high investment costs and the storage efficiency being less than those featuring alternative storage approaches, the proposed system may be considered of interest due to the long-life duration and the established technologies available for the key plant components.

Energy has always been the driving force in the technological and economic development of societies. The consumption of a significant amount of energy is required to provide basic living conditions of developed countries (heating, transportation, lighting, etc.). Today's energy supply has a considerable impact on the environment, since it is fuelled by the burning of fossil fuels. In addition to this, the fossil fuel reserves are decreasing while the demand for energy is rapidly rising. Climate change, the depletion and geographical segregation of fossil fuel resources, health related issues as well as energy poverty constitute the driving forces towards the pursuit of alternative energy sources. In addition, countries with no access to oil reserves are being dependent from other countries for their energy supply, with a strong impact on politics and financial issues. But apart from occasional financial recessions, the long-term need for increasing amounts of energy as countries develop will become a major rate limiting step in the growth of the world economy [1]. The last years there is an on-going research on alternative fuels in order to overcome the fossil energy dependence and to provide a sustainable growth of economies and societies.In view of the above, countries that release the largest amounts of greenhouse gases to the atmosphere compared to the energy production are expected to minimise CO 2 emission and at the same time improve the share of ''clean'' energy in total energy consumption. The renewable, non-conventional energy sources, such as solar and wind energy, will remain available for infinite period. But due to the inherent nature of renewable energy resources being intermittent, there is a need to store any surplus electrical energy produced in order to be used during high energy
