The paper reviews some important aspects concerning the low-potential energy utilization using so- called organic Rankine cycle (ORC). The recent increasingly frequent applications of ORC are as follows: thermal waste treatment in industries, thermal power of combustion engines, solar and geothermal power engineering, biomass energy, etc. Significant attention is given to issues of working fluid selection. There is a list of the most important requirements for the working fluid. The paper presents the analysis of references, which examine different aspects of ORC applications and reviews the possibilities of ORC modeling.
