Therefore, this study proposes a novel combined cooling, heating, and power system based on liquid CO2energy storage. Using direct refrigeration with a phase change, the system has a large cooling capacity and can achieve a wide range of cooling-to-power ratios through the mass flow regulation of the refrigeration branch.
The research findings indicate: After integrating LAES cooling utilization into CPVS, the efficiency of the 4.15 MW photovoltaic module increased from 30 % to 37.33 %, representing a growth of 24.41 %.
In conclusion, the integration of CPVS and LAES can enhance the solar energy utilization by leveraging the energy storage advantages and surplus refrigeration capacity of LAES units, prolonging the lifespan of CPV cells and improving the economic benefits of CPVS.
4.1. Standalone liquid air energy storage In the standalone LAES system, the input is only the excess electricity, whereas the output can be the supplied electricity along with the heating or cooling output.
Xin et al. (2015) conducted an experiment to cool the concentrating photovoltaic (CPV) systems by immersing them in dimethyl silicon oil with thickness = 1 mm: 30 mm. Figure 21 shows the schematic diagram of its setup; they studied the effect of the immersing fluid and its thickness on the electrical performance of the CPV systems.
However, the implementation of this solution requires a suitable energy storage method. Liquid Air Energy Storage (LAES) has emerged as a promising energy storage method due to its advantages of large-scale, long-duration energy storage, cleanliness, low carbon emissions, safety, and long lifespan.
