CO₂ Capture and Geologic Storage: The Possibilities

Abstract

Carbon dioxide (CO(2)) capture and geologic storage has been postulated as one possible method to stabilize the atmospheric concentration of CO(2) by injecting and storing it in deep geologic formations. This issue paper analyzes the viability of capture and geologic storage of becoming an effective method to aid in stabilizing the atmospheric concentration of CO(2). It is herein shown that such viability is contingent on overcoming major obstacles that are hydrogeological, technical, and economic in nature. Our analysis indicates that capture and geologic storage is likely to have negligible success in reducing the atmospheric buildup of CO(2) in the coming decades. The magnitude of the anthropogenic emissions of CO(2) indicates that a transition of the world economy away from reliance on fossil fuels might be the only path to stabilize its atmospheric concentration.

Effect of the structural constituents of metal organic frameworks on carbon dioxide capture

“…This technology encompasses CO 2 capture and CO 2 separation from other gases present in the ambient air or post combustion flue gas, transportation of captured CO 2 , and its proper storage [4,5]. As of 2012, there…”

Experimental Examination of Fluid Flow in Fractured Carbon Storage Sealing Formations

“…In an attempt to reduce the anthropogenic CO 2 released to the atmosphere, geologic CO 2 sequestration is being actively examined. Carbon capture, utilization, and storage (CCUS) involves pumping CO 2 far below the surface of the earth into high permeability (k) and high porosity () reservoirs, which have a low k and low  seal formation above the reservoir to stop the vertical migration of the CO 2 back to the surface [2,3]. Numerical simulations, cost benefit analysis, and field tests are all underway to determine the feasibility of CCUS as a greenhouse gas mitigation activity.…”

“…A typical vertical fracture geometry is shown in Figure 1 where the aperture, b, is much less than the fracture width, W, height, H, and length, L. Flow through rock fractures has been a research topic of interest for decades [4,5]. Analytical models were developed for laminar, single phase fluid flow in a narrow fracture, bounded by impermeable walls, by simplifying the Navier-Stokes equations of fluid continuity 3…”
