Abstract:
Petrothermal reservoirs contain a tremendous technical potential without major regional restrictions.The application of supercritical CO2(sCO2) as a heat carrier might be a promising alternative to thecommonly discussed usage of water. This study evaluates both heat carriers for a CHP application. A novel CHP plant layout for a thermosiphon with direct utilization of sCO2 for power generation and apumped brine system with a parallel CHP plant and power generation by an Organic Rankine Cycle (ORC...     »
