CO2-DISSOLVED (Kervévan et al, 2014) is a multinational project funded by the French National Research Agency (ANR) with Phase II funded as one of the first Geodenergies projects. Geodenergies is a French industry-driven initiative grouping 18 companies and research organizations aiming at: (1) structuring a community of expertise to promote subsurface energy technologies that are key to a global energy transition; (2) cross-fertilizing to develop 3 emerging industrial sectors: geothermal energy production, underground CO 2, and energy storage. As the name " CO2-DISSOLVED " implies, the project focuses on the feasibility of the injection of dissolved CO 2 in water, as opposed to supercritical CO 2 injection. In this, and drawing from a process originally developed at a US Department of Energy (DOE) laboratory, Partnering in Innovation, Inc. (Pi-Innovation) offers a novel aqueous gas separation and carbon capture approach. Specific features in the design uniquely integrate multiple energy recovery processes and the potential for contaminant removal (i.e., oxides of sulphur (SOx), nitrogen (NOx), selenium (SeOx), and mercury (HgOx). CO 2-DISSOLVED uses a simplified version of this approach but here we present the process modelling results and testing design for the full gas separation technology.
