Novel fluids for enhanced carbon storage

Carbon dioxide (CO2) has been used as a carbon carrier for geological carbon storage.  However, various shortcomings come from its physical properties, such as low carbon density at low to moderate pressure, low mass density, low viscosity, immiscibility with water, and corrosivity.  We present studies of using novel carbon-bearing fluids for geological carbon storage; namely, aqueous formate solution and aqueous nanobubble-dispersion/gas-supersaturation.  This presentation shows a summary of physical and transport properties of these novel fluids and then presents numerical simulation case studies for geological carbon storage.  Details of the novel fluids will be also presented as part of the posters in the Energi Simulation Summit.
