Mitigating the consequences of global warming on the shortage of water and sustainable energy requires clean technologies, such as solar energy systems. In this regard, integrating multiple clean technologies can provide an effective solution for simultaneous sustainable energy and freshwater production. In this study, a novel hybrid system integrating a Solar Chimney Power Plant (SCPP), solar still, and Concentrated Solar Power (CSP) system are proposed and numerically investigated. The proposed design lies in utilizing the CSP system as an auxiliary thermal energy source to enhance both airflow inside the chimney and evaporation inside the solar still simultaneously. Conducted computational Fluid Dynamics Analysis (CFD) for a system comprised of a 12 m height chimney and 3.4 m solar collector, accompanied by solar still basins located under the transparent collector, and the added CSP system showed that the basin temperature reached approximately 72 °C, and the water temperature in the collector outlet increased to about 62 °C in the triple system. Also, the chimney inlet velocity reached 2.2 m/s. The power generated in the new design showed a 68.2% increase via producing 0.64 W compared to the base case; meanwhile, the water production was 7554 g, indicating 18% rise in desalination capability. The observed results highlighted the substantial impact of additional thermal energy on system performance obtained from the CSP system compared to conventional hybrid systems.
