This is a broad review on recent developments in hybrid SCPP systems that incorporate additional technologies to address these limitations and improve overall performance. Key results prove that the combination of SCPPs and external sources of heat (flue gases, geothermal energy, e.g. 75 degrees C hot springs, or nuclear power plant waste heat) allows the SCPPs to be continuously operated, which can be improved significantly to increase the energy production; e.g., integrations with nuclear heat tripled the monthly electricity yield of 25.73 MWh to 63.81 MWh and doubled freshwater production. Photovoltaic (PV) panel integration not only creates more electricity, but also enjoys cooling effects in the collector, enhancing PV efficiency by up to 7 % and total system power production by 5.98 %. Moreover, hybrid systems with desalination and water generation capabilities demonstrated impressive performance, with one new twin-chimney system yielding 209,165 tons of distilled water and energy production 2.9 times more than a conventional SCPP. Ventilation and cooling through phase change materials (PCMs) or earth-air heat exchangers increased ventilation rates by up to 7.2 % and decreased building cooling demand by 40 %. Finally, hybridization offers SCPPs a game-changer and improves their functioning in numerous aspects, allows them to perform the functions of multi-utility system that generates power, desalinates, and purifies the air and makes them far more economically and environmentally sustainable.eninfo:eu-repo/semantics/closedAccessHybrid Solar Chimney Power Plant (HSCPP)Power GenerationPhotovoltaic (PV) IntegrationGeothermal EnergySustainable EnergyPerformance EnhancementArticle
