Progress of thermoelectric power generation systems: Prospect for small to medium scale power generation

Abstract

Abstract This paper presents the progress of thermoelectric power generation systems and their potential to be incorporated in small to medium scale power generation systems with encouraging prospects of grid connection. To begin with this paper demonstrates the urgency and necessity of finding an alternative source of energy to replace the existing inclination of human race towards fossil fuels. Following this the potential of thermoelectric technology to be used with alternate energy sources is demonstrated. Development in the field of thermoelectric materials with high Seebeck coefficients, suitable for power generation modules is discussed in the literature review. New advanced materials and innovative techniques to utilise renewable energy for power generation using thermoelectric generators are described in the main body of this paper. Various active and passive cooling systems with thermoelectric power generation modules to enhance the performance of the system are illustrated in the paper. A brief literature survey is presented at the end about grid connection for thermoelectric generators .These advances in thermoelectric technology, places it in a comfortable position to become a major contributor to renewable and sustainable electricity production in the future, essentially replacing fossil fuels.
