This study investigates the potential of using R134a as a working fluid in a low-emission power plant instead of the conventional power plant to mitigate the greenhouse effect. The study explores the thermodynamic properties of R134a and its suitability for use in an Organic Rankine Cycle (ORC) power plant. A simulation model was developed using Aspen Hysys to evaluate the power plant’s performance using this working fluid. The results indicate that the ORC power plant can significantly reduce greenhouse gas emissions compared to conventional power plants while maintaining high energy efficiency. About 18.17 kW of electric power can be obtained at a working condition of 10 bar and an evaporator temperature of 130 °C with the highest thermal efficiency of 3.43%. The study provides valuable insights into the potential of R134a as a sustainable working fluid for low-emission power generation.
