“…In this regard, a specific share of the generated power, owing to the standard operating point of the compressors, is conveyed to the compression train; meanwhile, the remaining unstable and highly fluctuating power is used by the HTES component to produce and store heat power. 24 The compression process associated with heat generation can increase the power consumption of the compressors. Therefore, an intercooler and an aftercooler are equipped to avoid further power consumption.…”

“…Since the projected system works at two separate times, the charging and discharging periods, the conventional energy and exergy efficiencies cannot be applied to obtain the system performance. In this regard, the round trip energetic and exergetic efficiencies that are the proportion of energy generated in the CAES and Kalina turbines to the total energy consumed, including the compressor and pump train consumption and HTES heating energy, are employed to calculate the total energy and exergy performances of the reference system 24 :…”

A novel efficient and entirely green hybrid energy conversion system comprising compressed air energy storage and Kalina KCS11 is proposed for peak shaving application and grid stability. The use of high-temperature thermal energy storage as a replacement for the traditional combustion chamber and a Kalina KCS11 with clean working fluid aims to minimize greenhouse gas emissions while adequately addressing intermittency and electricity curtailment of power grids with high penetration of renewable sources. The proposed system is comprehensively analyzed from the energy, exergy, and economic viewpoints. The thermodynamic simulation results indicate that the air turbine and pressure regulating valve have, respectively, 595.5 and 477.5 kW exergy destruction, accounting for around 40% of total exergy destruction. In addition, employing a KCS11 cycle recovers 57.95% of the heat dissipated in the CAES outlet. Accordingly, the proposed hybrid CAES-KCS11 system has round trip energetic and exergetic efficiencies of 52.97% and 46.28%, respectively. The economic analysis reveals that along with environmental benefits, it has a reasonable payback time of around 3.69 years. Moreover, a total benefit of 740 000 $ is gained during the service year of the system. The hybrid system is found to be more efficient compared to a standalone high-temperature hybrid CAES system.

“…This process increases the efficiency of the system reducing the consumption of fossil fuels and, therefore, CO 2 emissions [70]. To reduce the handicaps of conventional CAES, different approaches have been considered such as reducing the target depth of the storage cavities [43] or the hybridization of energy storage technologies, such as the integration of CAES and hydrogen [63], and others [3,19,58,4].…”

The future electricity generation model will require the integration of intermittent renewable sources. For that, the development of new efficient and sustainable energy storage technologies is mandatory. One of the most promising technologies is the utilization of compressed air energy storage (CAES). However, this technology has a limitation related with the management of the heat generated in the compression stage. In this study it is proposed the integration of a CAES system together with an anaerobic digester, which will use the generated heat, supporting the production and storage of biogas as chemical storage of energy. The latter will be used in the air expansion stage to maximize the efficiency of the overall process. In this way, a new energy storage technology by hybridization of BIOgas and CAES is achieved: BIO-CAES technology.

Summary A multigeneration system comprising solid oxide fuel cell, compressed air energy storage, gas turbine, supercritical CO2 recompression Brayton cycle (S‐CO2), and organic flash Rankine cycle (OFRC) based on liquefied natural gas cold energy is proposed. The system integrates peak shaving, heating, cooling, power generation, and energy storage, solving the imbalance between the supply and demand of renewable energy. It is comprehensively analyzed from the thermodynamic, economic, and exergoeconomic perspectives to evaluate the performance of the three phases (full time, charging period, and discharging period). The evaluation shows that the exergy analysis of the multigeneration system alone is not comprehensive, and the exergoeconomic analysis is more necessary. Additionally, the S‐CO2 coupled with the OFRC generates power in a more efficient way than the S‐CO2 coupled with the Organic Rankine cycle (ORC) or Organic Flash cycle (OFC) does. Finally, the NSGA‐II and multi‐objective whale algorithms are employed to optimize the system. The results show that the multi‐objective whale algorithm is slightly better than the NSGA‐II. Moreover, the optimized round‐trip efficiency (RTE) and levelized cost of electricity (LCOE) are 68.64% and 0.053 $ kWh−1, respectively. Compared with the base design point, the RTE improves by 1.93%, and the LCOE decreases by 3.64%.
