Abstract
• Explores the role of Organic Rankine Cycle (ORC) technology in addressing global warming and the energy crisis. • Provides a comprehensive survey of previous studies on working fluid (WF) selection for ORC systems. • Evaluate the performance of WFs in subcritical ORC configurations using environmental and thermo-economic indicators. • Highlights the critical impact of WF properties on ORC performance and system design optimization. • WF optimization in ORC systems offers insights into sustainable and efficient heat recovery. The urgent need to mitigate global warming and the energy crisis has driven the exploration of zero-carbon energy solutions. The organic Rankine cycle (ORC) offers an efficient method to utilize low-grade heat sources while adhering to environmental constraints. This study comprehensively reviews factors influencing working fluid (WF) selection for ORC systems, highlighting their critical role in system performance and design. Additionally, the study evaluates WF performance across various subcritical ORC configurations using environmental and thermo-economic indicators.
