ABSTRACT: In this study a thermodynamic analysis of a hybrid renewable power generation system is presented. The scope of research is to utilize LNG to increase the overall efficiency of Concentrated Solar Thermal Power generation systems (CSP). A cryogenic Rankine bottoming cycle is incorporated within the CSP power standard vapor Rankine cycle named as topping cycle. A thermodynamic analysis is carried out for the two different models, the first model is the simple cycle from the Concentrated Solar Power technology, and the second model which includes the cryogenic cycle named as combined cycle. The analysis showed the power out of the combined cycle can be increased by 66% of the original power produced by steam cycle, while, the efficiency of the combined cycle can be increased by 45% over the original simple cycle.
KEYWORDS: Concentrated Solar Power, LNG, Propane Cycle.
