Assessment of working fluids, thermal resources and cooling utilities for Organic Rankine Cycles: State-of-the-art comparison, challenges, commercial status, and future prospects

Muhammad Abdul Qyyum et al.

Summary: This paper presents a state-of-the-art review on organic Rankine cycle (ORC) technology, examining the working fluids, thermal resources, cooling utilities, and commercial status. The study finds that mixed working fluids achieve higher thermodynamic efficiency, but their application is limited by difficulties in determining the optimal composition and components. Low-temperature ORC systems utilizing waste heat and geothermal energy are prevalent, while biomass and solar energy are underutilized as heat resources for ORC. The United States and Europe are leading in commercial applications of ORC for converting low-grade waste heat into useful power. The main challenges for ORC are selecting suitable working fluids and expanders, as well as reducing the specific cost of small-scale ORC systems to compete with renewable energy. Future research directions include investigating the overall performance, stability, and safety of ORC systems, developing a general methodology for selecting working fluids, and conducting techno-economic optimization studies to reduce costs. This study provides an overview of the recent progress in ORC technology and highlights the scientific problems that need to be addressed to harness low-grade heat for power generation in the future.
