A thorough performance assessment of solar chimney power plants: Case study for Manzanares

open access: yesCleaner Engineering and Technology, 2020
Solar chimney power plants (SCPPs) are promising systems for clean energy generation. SCPPs are ideal for the large-scale harnessing of solar energy. They operate efficiently without auxiliary energy and do not cause any environmental pollution.

Impact of the geometry of divergent chimneys on the power output of a solar chimney power plant

open access: yesEnergy, 2017
Abstract Divergent chimney is proposed to be an alternative for Solar Chimney Power Plants (SCPPs) because of their reported remarkable improvement in power output over cylindrical chimneys. However, the power output of divergent SCPPs in those studies changed from several percentage to >100 times higher than that of cylindrical ones.
