Storage of Captured Anthropogenic CO2 in Ocean Sediment
An essential problem of CO2 capture and storage technologies is finding sufficiently large geologic depositories to store the captured anthropogenic CO2. Additionally, due to the subsurface temperature profile of terrestrial storage sites, CO2 stored in these reservoirs is buoyant. As a result, a portion of the injected CO2 can escape if the reservoir is not appropriately sealed. In addition, CO2 capture with geologic storage can only serve to limit the rate of rise of CO2 concentrations. To decrease the concentration of atmospheric CO2, processes must be developed to remove CO2 directly from the atmosphere. The central objective of this Link Foundation supported research was to explore new approaches to storing captured CO2 and for removing CO2 from the atmosphere.
