520 ▼a CO2 capture and sequestration in deep saline aquifers is widely considered to be a leading option for controlling greenhouse gas emissions. One such possibility involves injection of supercritical carbon dioxide (sCO 2) into a high-permeability
520 ▼a As geothermal energy is widely recognized as a low grade heat source, power cycles with capabilities to convert low grade energy into electricity, such as Organic Rankine Cycle (ORC), have been considered. Additionally, sCO 2-based power cycles
520 ▼a Possible cycle improvement methods have been taken into consideration and different configurations of sCO2-based power cycles have been analyzed thermodynamically. The direct turbine expansion, sCO2 Brayton cycle with pre-compression and inter-c
520 ▼a Analyses have been performed to investigate the effects of reducing the cooling O&M cost and counting CO2 credit of sequestration on the LCOEs. It has been found if the cooling O&M cost is reduced to one quarter of the original value, the LCOEs
