Addressing Complex SCPP Challenges with AI
Conventional Solar Chimney Power Plants are hindered by low energy conversion efficiency and the absence of integrated strategies for maximizing simultaneous green hydrogen and electricity production. This challenge is amplified by the non-linear interactions of multiple interdependent system parameters, making traditional optimization methods inadequate.

Our study introduces a novel hybrid SCPP configuration, optimized for both electricity and green hydrogen, through a sophisticated AI framework. By systematically analyzing the intricate interplay of chimney inclination, solar radiation, collector absorptivity, and turbine pressure drop, we demonstrate how AI can model complex buoyancy-driven flows and integrate an electrolysis unit for hydrogen generation.
This approach moves beyond single-output designs, establishing an effective operational envelope that leverages AI's predictive capabilities to maximize both energy yields and accelerate sustainable energy transitions for industrial-scale deployment.
