An Overview of Polygeneration as a Sustainable Energy Solution in the Future

Abstract

Better systems can be produced from various utility outputs that are integrated to make choices. The emergence of polygeneration after triggers and cogeneration can be used as sustainable solutions, making it possible to utilize resources optimally, efficiently and environmentally friendly. Polygeneration can be conceptualized with several possibilities because, theoretically, the working system has been well received as contained in some literature. Various scientific works have reported that the input and output vary greatly. The results of experimental analyses and prototypes developed have also been widely investigated and reported. Optimization tools that are based on the function of each objective are also used as a step to develop polygeneration effectively and efficiently. Polygeneration assessment has multidimensional criteria and their definitions can be applied based on cases with specific objectives. The main objective of this article is to comprehensively review the various literature available to investigate the status of polygeneration for renewable and sustainable energy solutions in the future. Various possible logical and predictable future works on polygeneration are also discussed at the end of this article.

Design and Operation of a Polygeneration System in Spanish Climate Buildings under an Exergetic Perspective

“…In general, polygeneration systems are designed to satisfy a percentage of the building's thermal or electrical demand; an overview of polygeneration solutions is given in reference [3]. The advantages of polygeneration systems include the following aspects:  They have a better performance than separate generation and, therefore, they save primary energy and reduce the energy bill.…”
