Enhanced safety of geologic CO 2 storage with nanoparticles
Abstract
In this paper, some methods have been developed to detect leakage of CO 2 from its desired storage domain, but that is not sufficient to prevent and mitigate a leak. Two techniques have been proposed to prevent the migration of buoyant CO 2 from the storage domain by expediting mixing of CO 2 with the brine and mitigate risk of its leakage risk. These two methods are injection of CO 2 pre-mixed with brine, and injection of CO 2 with nanoparticles (NPs). The former has been studied to some extent, however, understanding of the latter is very limited. Unlike the application of NPs in hydrocarbon recovery, its use to enhance safety of CO 2 storage is a fairly unexplored topic that can have important benefits for the safety of the storage process. Also, the use of NPs for subsurface application in general is compromised for its cost. We investigate how NPs produced from low-level nuclear waste can be added with injected CO 2 to enhance the mixing of CO 2 with brine, which can mitigate leakage risk of CO 2.
