Concentrated solar power (CSP) systems are one type of renewable energy technology that has the capacity to capture solar radiation and convert it into thermal energy that can be put to use. There is a direct correlation between the performance of a CSP system and the efficacy and efficiency of the heat transfer fluid that is utilised in the system. The purpose of this study is to investigate the many functions that heat transfer fluids perform in CSP systems and how those functions influence the overall performance of the system. The purpose of this study is to investigate several elements of heat transfer fluids, such as their thermal stability, heat capacity, viscosity, and effects on the surrounding environment. This work provides insights into optimising the choice and utilisation of heat transfer fluids in CSP systems by doing an in-depth investigation of the relevant literature, proposing a system design, and conducting experimental research. The findings provide credence to the efficient utilisation of solar power for the generation of renewable power while also highlighting the need to advance and perfect CSP technology.
