Assessment of CO2 Plume Geothermal (CPG) Systems

Abstract

CPG systems have been compared with conventional hydrothermal power plants based on thermodynamic simulation calculations. Especially at moderate reservoir depths and permeabilities, significant performance benefits for CO2 system were observed which validates the results from literature.Considering the surface power plant layout a less complex CO2 cycle with less equipment and a smaller footprint in comparison to brine based systems can be derived.
