Low-Temperature Enhanced Geothermal System using Carbon Dioxide as the Heat-Transfer Fluid

[摘要] This report describes work toward a supercritical CO₂-based EGS system at the St. Johns Dome in Eastern Arizona, including a comprehensive literature search on CO₂-based geothermal technologies, background seismic study, geological information, and a study of the possible use of metal oxide heat carriers to enhance the heat capacity of sCO₂. It also includes cost estimates for the project, and the reasons why the project would probably not be cost effective at the proposed location.
