Abstract

Interest in combined heat and solar power (CHP) systems has grown due to the rising demand for sustainable energy with low carbon emissions. One effective technical solution is the use of a parabolic trough solar collector (PTC) in combination with a Rankine cycle (RC) heat engine. The solar-powered Rankine cycle (SPRC) system is a renewable energy technology that offers high efficiency and clean energy output. This study investigates the techno-economic performance of an SPRC system designed for electricity generation in Aden, Yemen, a location with substantial solar energy potential. The proposed system includes parabolic trough collectors, a thermal storage tank, and a Rankine cycle unit. A comprehensive 4E (energy, exergy, economic, and environmental) analysis was conducted to examine the impact of design parameters, including boiler pinch point temperature, turbine steam extraction ratios, and condenser temperature. Simulation results indicate that the system can generate a net power capacity of 50 MW with efficiency levels that demonstrate competitive performance under local climatic conditions. The analysis also highlights the economic feasibility and environmental benefits of adopting the SPRC system. Overall, the findings show that implementing such a system could significantly reduce Yemen’s dependence on fossil fuels, lower greenhouse gas emissions, and enhance long-term energy security. This study makes a unique contribution by providing one of the first techno-economic assessments of a solar-powered Rankine cycle system tailored to Yemen’s specific energy challenges
