Parabolic Trough Collector (PTC) and Thermoelectric Generator (TEG) Based Multigeneration Systems for Low/Zero Carbon Buildings: A Review

Abstract

The growing need for sustainable and efficient energy solutions for low/zero carbon buildings has accelerated the development of hybrid technologies. Parabolic Trough Collector (PTC) and Thermoelectric Generator (TEG) based multi-generation systems stand out as promising solutions in this field. This study examines the integration of PTC and TEG technologies, highlighting the complementary power and potential application areas of these systems. While PTC systems are known for their ability to capture high-temperature solar energy, TEGs have the capacity to generate electricity by utilising temperature differences. Hybridisation of these technologies increases energy efficiency, system flexibility and sustainability. Examining various design configurations, operating principles and application areas, this study reveals the role of PTC-TEG hybrid systems in achieving multiple production goals such as electricity generation, water treatment, heating/cooling and hydrogen production. The results show that PTC-TEG hybrid systems not only improve energy conversion processes but also support environmental goals and play a critical role in the transition to a sustainable energy future.
