Liquid air energy storage (LAES) technology is helpful for large-scale electrical energy storage (EES), but faces the challenge of insufficient peak power output. To address this issue, this study proposed an efficient and green system integrating LAES, a natural gas power plant (NGPP), and carbon capture. The research explores whether the integration design is theoretically feasible for future adoption in operating the LAES system and NGPP. The effect of the charging pressure, the number of air expansion stages, and electricity prices on the overall thermodynamic and economic characteristics are investigated. The round-trip efficiency and the exergy round-trip efficiency of the proposed system are 47.72% and 69.74%, respectively. The calculations show that the minimum dynamic payback period for such a project is 3.72 years, and the lowest levelized cost of electricity is 0.0802 USD·kWh−1. This work provides a reference for peak-shaving power stations with energy storage and carbon capture.

“…Due to the advantages of easy access to carbon dioxide and good physical properties, CCES technology is developing rapidly at present. The research work of the refrigeration cycle and Brayton cycle with carbon dioxide as the working system has been paid attention to, and the research on the carbon dioxide system has been more mature [31]. However, there is still a big deficiency in the research of using carbon dioxide as the working system of compressed-gas energy storage systems.…”

Compressed carbon dioxide energy storage (CCES) offers several benefits over other existing energy storage systems, including ease of liquefaction, high energy storage density, and environmental friendliness. As a result, the research progress, economic and technological feasibility, and system operation of the CCES system are all discussed in depth in this study. The system evaluation method is summarized and the compressed carbon dioxide storage is analyzed, and the performance optimization direction of the compressed carbon dioxide energy storage technology is discussed. When the overall performance of a transcritical CCES system, a supercritical CCES system and a liquid CCES system are compared, it is discovered that the supercritical CCES system has better thermodynamic characteristics and a simpler system configuration, making it suitable for large-scale development and use. The goal of the CCES system's future development is to create a design with an optimum compression and expansion ratio, a more precise analysis and system model, and multi-field coupling. This review's discussion serves as a guide for the best design and use of the CCES system.

The energy storage device is indispensable in future power system due to the high share of renewable energies. Compressed gas energy storage (CGES) technology, including the compressed air energy storage (CAES), has been widely recognized as one of the most promising solutions in energy storage domain. Among multiple CAES forms, the isothermal CAES is a potential type in which the ideal round trip efficiency (RTE) can be 100%. On the other hand, carbon dioxide (CO 2 ) as an excellent working medium in CGES system owing to its favorable properties. However, the existing isothermal type CGES systems just employ the air as working medium, the potential of CO 2 in such system is not evaluated yet. Therefore, an 800 kW pumped hydro assisted near-isothermal compressed carbon dioxide energy storage system with gas/liquid phase change process is proposed. In detail, the hydraulic machineries, the flexible rubber diaphragm and the helical coils are employed to realize the near-isothermal process and high RTE. The transient models are built and system performance is thus investigated. The results show that the system possesses 68.36% in RTE and 1.0914 kWh/m 3 in energy density (ED) under the design condition. Meanwhile, the water temperature in helical coil, the initial and maximum pressures of vessel and the vessel volume are sensitive for system behavior.carbon dioxide, compressed gas energy storage, near-isothermal process, Pelton turbine, performance analysis | INTRODUCTIONTo fulfill the Paris Agreement and step towards a sustainable society, the energy sector should make more effort to build a new power system.
