The CO2-DISSOLVED project aims at assessing the technical-economic feasibility of coupling dissolved CO2 storage in a saline aquifer and geothermal heat recovery. It targets specifically low-medium tonnage CO2 emitters (ca. 10-150 kt/yr) because the amount of dissolved CO2 that can be injected into a geothermal saline aquifer is physically limited by the solubility of CO2 in brine. This work makes an inventory of the potential candidates to the CO2-DISSOLVED concept in France, Germany, and the U.S.A. The results evidenced that relatively large geothermal areas match the presence of many industrial sources emitting low rates of CO2, allowing us to conclude on the potential applicability of the concept in these three countries.
