The usage of exhaust gas heat in WHR (Waste Heat Recovery) systems and its conversion into electrical energy using ORC technologies is limited by the thermal stability of working bodies at a temperature of exhaust gases above 270–300 ºС. Therefore, thermal schemes of hybrid power plants, in which water vapour and organic heat carriers are used as working fluids, are being developed. Numerous studies indicate that the efficiency of the thermal scheme of energy conversion is significantly influenced by the properties of working bodies and their parameters. Due to the large number of working bodies, the problem of their thermodynamic parameter effect has not been sufficiently studied. This paper [13] presents a review on hybrid renewable energy power generation systems focusing on energy sustainability.
