this review article presents a comprehensive analysis of the thermodynamic application of thermal energy storage (TES) to combined heat and power (CHP) plants. The integration of TES technologies in CHP systems has garnered increasing attention as a means to enhance energy efficiency, improve system flexibility, and optimize the utilization of heat and power resources. Through a thorough examination of existing literature, this review highlights the key findings, challenges, and opportunities in this field. The review begins by discussing the principles of TES and CHP systems, outlining their respective advantages in energy storage and simultaneous heat and power generation. It then delves into the various TES technologies suitable for integration with CHP plants, including sensible heat storage, latent heat storage, and thermo chemical storage. The advantages and limitations of each technology are analyzed in the context of CHP applications. A significant portion of the review focuses on the performance enhancement achieved through TES integration in CHP plants. Studies evaluating the impact of TES on the efficiency, load balancing, and operational flexibility of CHP systems are critically examined. The analysis underscores the potential of TES to mitigate the intermittency challenges associated with renewable energy sources and its role in supporting grid stability and demand response programs. Moreover, the review addresses the techno-economic aspects of TES implementation in CHP plants. Various studies exploring the cost-effectiveness return on investment and overall economic viability of integrated systems are discussed. Furthermore, it highlights the importance of life cycle assessments in evaluating the environmental benefits and sustainability implications of TES-integrated CHP. Several real-world case studies and pilot projects are reviewed to provide insights into the practical application of TES in existing CHP plants. These case studies offer valuable information on system design considerations, performance optimization, and lessons learned from implementation experiences.
