description abstract | This Special Section of ASME Journal of Energy Resources Technology (JERT) presents selected scientific output of the 7th Conference on Contemporary Problems of Thermal Engineering (CPOTE2022), which brings together scientists involved in advanced energy, exergy, and ecological analysis.1 The main theme of CPOTE2022 was towards sustainable and decarbonized energy system. CPOTE2022 was held in Warsaw, Poland, between September 20 and 23, 2022. Since its 1st edition in 1998, the CPOTE conference has become a cyclic event gathering the most recognized scientists in the areas of thermodynamics, energy, and environmental engineering. Compared to other conferences dedicated to thermodynamics and energy, CPOTE focuses among others on exergy analysis to a larger extent. The CPOTE conference is mainly dedicated to contemporary problems of energy systems.2 | |
