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

Abstract

This report describes work toward a supercritical CO 2-based EGS system at the St. Johns Dome in Eastern Arizona, including a comprehensive literature search on CO 2-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 sCO 2. It also includes cost estimates for the project, and the reasons why the project would probably not be cost effective at the proposed location.
