Fundamental study of multiphase CO₂ evolution and attenuation in shallow aquifers during possible leakage from deep geologic sequestration sites using multi-scale experimental testing and numerical modeling
Geologic Carbon Sequestration has the potential to significantly reduce carbon dioxide (CO2) emissions, but the potential for leakage of CO2 from deep storage formations into the shallow subsurface presents a wide range of possible risks that must be understood and addressed. The type, extent and severity of the risks depend on the distribution and multi- phase behavior of the CO2. For instance, dissolved CO2 causes acidification of groundwater, which could lead to mobilization of other contaminants such as metals. On the other hand, when water containing dissolved CO2 migrates through shallow ...
