Abstract:
Carbon dioxide enhanced geothermal system (CO2-EGS) now is an emerging research field that is attracting an increasing research interest with broad application prospects based on its low-carbon, economical and renewable features. The fluid flow and heat transfer is the core of CO2-EGS research. In this paper, further research focus is pointed out after summarizing the latest research progress in this field based on the explanation and the advantages of CO2-EGS development process in the hope of providing reference for researchers engaged in this field.
