With the continuous increase in global greenhouse gas emissions, impacts of climate change are becoming increasingly severe. In this context, geothermal energy has gained significant attention due to its numerous advantages. Alongside advancements CO2 geological sequestration technology, use as a working fluid systems emerged key research focus. Compared traditional water-based fluids, possesses lower viscosity and higher thermal expansivity, enhancing mobility reservoirs enabling more efficient heat transfer. Using not only improves extraction efficiency but also facilitates long-term within reservoirs. This paper reviews recent progress on Enhanced Geothermal Systems (EGS), with focus potential advantages improving exchange power generation capacity. Additionally, study evaluates mineralization effects reservoirs, well impact reservoir properties. Finally, discusses technological developments economic analyses integrating other technologies. By systematically reviewing EGS, provides theoretical foundation for future development using fluid.
