Abstract:
Current research activities in the field of geothermal binary power plants mainly aim for an enhanced performance of the power plant cycle at the design point. Experience from running power plants, however, shows that improving the design point performance is not the only issue since plant operation can deviate significantly from the design conditions. This contribution will therefore discuss general aspects of improving the annual net power output with focus on the cooling system. By means of numerical modelling and example case studies assuming a basic Organic Rankin Cycle (ORC) using dry cooling and wet cooling, main improvement aspects will be discussed for the design and operation of the cooling system.
