Development and Performance Analysis of a Thermoelectric Generator (TEG) System for Waste Heat Recovery and Power Generation in Industrial Applications: A Comprehensive Review
Abstract: The increasing global demand for energy and the simultaneous depletion of conventional energy resources have intensified the need for efficient energy utilization technologies. A significant portion of energy used in industrial processes and internal combustion engines is lost as waste heat, which contributes to environmental pollution and reduced system efficiency. This review paper focuses on the potential of thermoelectric generators (TEGs) for converting waste heat into useful electrical energy. Thermoelectric generators operate based on the Seebeck effect, enabling direct conversion of temperature differences into electricity without any moving parts. This paper reviews recent advancements in thermoelectric materials, system design, and performance optimization techniques for waste heat recovery applications. Various studies demonstrate that TEG systems can be effectively integrated into industrial exhaust systems, automotive engines, and high-temperature processes to generate sustainable power. The performance of TEG systems depends on factors such as temperature gradient, material efficiency, and thermal management. Although the conversion efficiency is relatively low, ongoing research in advanced materials and hybrid systems is improving their feasibility. The review concludes that thermoelectric generators offer a promising, eco-friendly solution for enhancing energy efficiency and reducing environmental impact through effective waste heat recovery.
