Review highlights operational capabilities and integration needs of solar power tower plants, suggesting essential improvements.
Concentrating solar power (CSP) plants, notably solar power tower (SPT) plants, have significant potential to generate carbon-free electricity. This work briefly overviews CSP technologies, whereas SPT is presented in greater detail. In addition, the essential requirements, solar irradiance, land, water needs, and grid proximity to install a CSP plant are explained. This work highlights the significance of integrating direct steam generation (DSG) technology with SPT plants. Depending on the solar field aperture area, operational DSG-based SPT plants can produce more electricity than molten-salt-based SPT plants. Also, a comprehensive review of SPT plant components and the most relevant literature is presented, along with a classification of their operational status. A research proposal is presented to study the off-design factors affecting the operation of SPT and its components. Hence, the literature reveals a lack of understanding of the effects of these factors on the thermal performance of solar receivers and the overall performance of SPT plants.
