“…The area ratio (AR), which represents the ratio of the chimney cross-sectional area to the chimney exit area, has been studied to determine its influence on power generation. The optimum AR for power generation is approximately 10 according to Hu et al [79], 4 according to Cuce et al [80], 16 according to Koonsrisuk et al [81] and Lebbi et al [82], 8.76 according to Xu et al [83], and 12.39 according to Vieira et al [84]. The optimum height of the chimney by divergent shape is addressed by Singh et al [85].…”

Solar chimney power plants (SCPPs) are encouraging sustainable energy sources due to their low cost, abundance, low maintenance, and eco-friendliness. However, despite significant efforts to optimize SCPP design, their efficiency and power generation capabilities remain limited. Researchers have explored modifications in plant geometry and hybridization to improve efficiency. Despite extensive work in this area, commercialization of SCPPs has not yet been achieved. Most of the research is numerical and may differ from real-world practical use. The number of experimental studies is also relatively small. To facilitate commercialization, further investigation with practical and feasible dimensions is required. This comprehensive review paper aims to provide an in-depth analysis of experimental approaches and advancements in the field of SCPPs. The paper begins with an introduction, highlighting the background, significance, and objectives of the review. It provides an overview of the plants, discussing their principles and operation as innovative renewable energy systems. The historical development and evolution of solar chimneys are explored, shedding light on their progression over time. Case studies of operational hybrid SCPPs are examined to showcase real-world applications and performance. The paper also addresses environmental impacts and sustainability considerations associated with SCPPs. Furthermore, recommendations for future research and development in this field are provided to guide researchers and industry professionals. This study focuses on the possibility of commercialization of both standalone and hybrid SCPPs.

“…The effective parameters in the design of the solar chimney have been studied in [1]. These studies include changing the outlet and inlet radius of the chimney [2], types of heat storage systems and its effect on the solar chimney [3] and [4], the effect of collector surface on output power [5] and the effect of collector radius and the intensity of solar radiation [6] and the study of variables to increase the outlet of the solar chimney. Research(s) has also been conducted on the cost estimate for this project in India [7, 8 and 9].…”

One of the ways to generate power from the solar energy is to use the solar chimney technology. In the present study, by examining the weather map of Iran and using GIS software for selecting the appropriate area for the power plant site, the four physical models proposed studied for the solar chimney. This study is a numerical simulation (by MATLAB) regarding four physical models of solar chimneys in the city of Bam site, in Kerman province. The difference between the four mentioned models of the solar chimney is in storage system and the use of air diffuser. The behaviors of all four models were examined according to the valid meteorological information on a specific day from the target site. According to the results of the simulation, which includes airflow speed in several internal parts of the chimney and the production capacity of each of the mentioned models, the best and most proper model of solar chimney can be selected for the studies site and a proper estimation of the final production can be obtained.
