“…Of note is the Decatur project in Illinois where 1 million tonnes (Mt) CO 2 have been injected. Additional large‐scale projects are in various execution stages, including the offshore Gorgon Project in Australia [ Brantjes , ; Flett et al ., ] and the onshore Quest project in Canada [ Bourne et al ., ; Brydie et al ., ]. While these projects have been very useful, we note that the collective annual injection rate of all currently operational projects is still below the output from one large coal‐fired power plant.…”

Carbon capture and storage (CCS) is the only viable technology to mitigate carbon emissions while allowing continued large-scale use of fossil fuels. The storage part of CCS involves injection of carbon dioxide, captured from large stationary sources, into deep geological formations. Deep saline aquifers have the largest identified storage potential, with estimated storage capacity sufficient to store emissions from large stationary sources for at least a century. This makes CCS a potentially important bridging technology in the transition to carbon-free energy sources. Injection of CO 2 into deep saline aquifers leads to a multicomponent, multiphase flow system, in which geomechanics, geochemistry, and nonisothermal effects may be important. While the general system can be highly complex and involve many coupled, nonlinear partial differential equations, the underlying physics can sometimes lead to important simplifications. For example, the large density difference between injected CO 2 and brine may lead to relatively fast buoyant segregation, making an assumption of vertical equilibrium reasonable. Such simplifying assumptions lead to a range of simplified governing equations whose solutions have provided significant practical insights into system behavior, including improved estimates of storage capacity, easy-to-compute estimates of CO 2 spatial migration and pressure response, and quantitative estimates of leakage risk. When these modeling studies are coupled with observations from well-characterized injection operations, understanding of the overall system behavior is enhanced significantly. This improved understanding shows that, while economic and policy challenges remain, CO 2 storage in deep saline aquifers appears to be a viable technology and can contribute substantially to climate change solutions.

“…The target injection zone is the upper massive sandstone and lower unit of the Dupuy Formation. The Dupuy storage units are overlain by siltstones and shales that form a continuous regional seal (Flett et al, 2008(Flett et al, , 2009. Recent plans for this site include pressure monitoring as part of a pressure management system, to allow injection of 200 million standard cubic feet (0.01 t) per day of CO 2 at an average rate of up to 3.65 million tons per year (Trupp et al, 2013).…”

“…In addition projects recently permitted or currently in planning provide information on how M&V experience garnered over the decade is coming into play at larger scales. Examples include Gorgon (Flett et al, 2009) from Australia, Peterhead, ROAD and White Rose from Europe, Quest (Bourne et al, 2014) from Canada, Tomakomi from Japan and Decatur Phase II, Hastings, Kevin Dome and West Ranch from the US. Summaries of outcomes of many of these projects can be found in Cook (2014), NETL (2009); and at online data bases maintained by the Massachusetts Institute of Technology Energy Institute (MITei, 2010) and the Global CCS Institute (GCCSI, 2014b).…”

a b s t r a c tIn the ten years since publication of the IPCC Special Report on CCS, there has been considerable progress in monitoring and verification (M&V). Numerous injection projects, ranging from small injection pilots to much larger longer-term commercial operations, have been successfully monitored to the satisfaction of regulatory agencies, and technologies have been adapted and implemented to demonstrate containment, conformance, and no environmental impact. In this review we consider M&V chiefly from the perspective of its ability to satisfy stakeholders that these three key requirements are being met. From selected project examples, we show how this was done, and reflect particularly on the nature of the verification process. It is clear that deep-focussed monitoring will deliver the primary requirement to demonstrate conformance and containment and to provide early warning of any deviations from predicted storage behaviour. Progress in seismic imaging, especially offshore, and the remarkable results with InSAR from In Salah are highlights of the past decade. A wide range of shallow monitoring techniques has been tested at many sites, focussing especially on the monitoring of soil gas and groundwater. Quantification of any detected emissions would be required in some jurisdictions to satisfy carbon mitigation targets in the event of leakage to surface: however, given the likely high security of foreseeable storage sites, we suggest that shallow monitoring should focus mainly on assuring against environmental impacts. This reflects the low risk profile of well selected and well operated storage sites and recognizes the over-arching need for monitoring to be directed to specific, measureable risks. In particular, regulatory compliance might usefully involve clearer articulation of leakage scenarios, with this specificity making it possible to demonstrate "no leakage" in a more objective way than is currently the case. We also consider the monitoring issues for CO 2 -EOR, and argue that there are few technical problems in providing assurance that EOR sites are successfully sequestering CO 2 ; the issues lie largely in linking existing oil and gas regulations to new greenhouse gas policy. We foresee that, overall, monitoring technologies will continue to benefit from synergies with oil and gas operations, but that the distinctive regulatory and certification environments for CCS may pose new questions. Overall, while there is clearly scope for technical improvements, more clearly posed requirements, and better communication of monitoring results, we reiterate that this has been a decade of significant achievement that leaves monitoring and verification well placed to serve the wider CCS enterprise.Crown
