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.
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 this context, Concentrated Photovoltaics (CPV) play a crucial role in renewable energy generation and carbon emission reduction as a highly efficient and clean power generation technology .
Thus, the development of large-scale Concentrated Photovoltaic Systems (CPVS) has been propelled by the concentration of sunlight onto efficient CPV cells using low-cost reflectors or lenses .
Net Work Power Consumption or Output by Key Components of the LAES. The integrated system utilizes the cold air remaining from the cold box storage process (stream 19, Fig. 1) as a cooling source, exchanging heat with the cooling medium, cooling water (PV1, PV2), in the CPV cooling system.
A comprehensive thermodynamic analysis optimizes the coupled system’s operation and evaluates its economic benefits. The integrated system improves generation efficiency and economic viability of CPVS, resulting in a 24.41 % increase in photovoltaic module efficiency and a 2.03 % increase in overall rated power output.
