Résumé

Waste heat and solar power are viable alternative sources to generate electricity and reduce power production by conventional fuel burning thermal cycle power plants. On the one hand, Organic Rankine cycles (ORCs) are widely used to harness waste heat sources especially in the low-to medium temperature ranges, but they are characterized by relatively low thermal efficiency. On the other hand, steam Rankine cycles and supercritical CO2 Brayton cycles represent the state-of-the-art of solar concentrated power systems with peak thermal efficiencies of approximately 40%. To improve energy conversion efficiency in the low to medium source temperature range, a novel chemical reactive power cycle (CRPC) with a system layout similar to that of a basic ORC has been proposed by authors. The working fluid is allowed to undergo chemical reactions and useful work is extracted from both the expansion process and a fuel cell. In this work, the working fluid selection for different temperature ranges and applications is investigated.
