This study investigated how subsurface and atmospheric leakage from geologic CO 2 storage reservoirs could impact the deployment of Carbon Capture and Storage (CCS) in the global energy system. The Leakage Risk Monetization Model was used to estimate the costs of leakage for representative CO 2 injection scenarios, and these costs were incorporated into the Global Change Assessment Model. Worst-case scenarios of CO 2 leakage risk, which assume that all leakage pathway permeabilities are extremely high, were simulated. Even with this extreme assumption, the associated costs of monitoring, treatment, containment, and remediation resulted in minor shifts in the global energy system. For example, the reduction in CCS deployment in the electricity sector was 3% for the Bhigh^leakage scenario, with replacement coming from fossil fuel and biomass without CCS, nuclear power, and renewable energy. In other words, the impact on CCS deployment under a realistic leakage scenario is likely to be negligible. We also quantified how the resulting shifts will impact atmospheric CO 2 concentrations. Under a carbon tax that achieves an atmospheric CO 2 concentration of 480 ppm in 2100, technology shifts due to leakage costs would increase this concentration by less than 5 ppm. It is important to emphasize that this increase does not result from leaked CO 2 that reaches the land surface, which is minimal due to secondary trapping in geologic strata above the storage reservoir. The overall conclusion is that leakage risks and associated costs will likely not interfere with the effectiveness of policies for climate change mitigation.

“…Reasons include ubiquity, availability of mature technology, high storage capacities, and the potential for CO 2 conversion to carbonate minerals (Bachu and Adams 2003;Goldberg et al 2008Goldberg et al , 2010McGrail et al 2006). Estimates for CO 2 storage capacity in single, deep nonpotable aquifers range from 10 -2 to 10 4 Gt (Herzog 2001;McGrail et al 2006;Goldberg et al 2008;Gislason et al 2010;Donda et al 2011;Medina et al 2011) and would be sufficient for storing decades to centuries of future CO 2 emissions. For example, the estimated CO 2 storage capacity of deep basaltic aquifers on the Juan de Fuca ridge off Vancouver Island (part of British Columbia and northwestern Washington State), is believed to be equivalent to about 122-147 years of U.S. future CO 2 emissions (Goldberg et al 2008).…”

Leakage from deep storage reservoirs is a major risk factor associated with geologic sequestration of carbon dioxide (CO 2 ). Different scientific theories exist concerning the potential implications of such leakage for near-surface environments. The authors of this report reviewed the current literature on how CO 2 leakage (from storage reservoirs) would likely impact the geochemistry of near surface environments such as potable water aquifers and the vadose zone.Experimental and modeling studies highlighted the potential for both beneficial (e.g., CO 2 re-sequestration or contaminant immobilization) and deleterious (e.g., contaminant mobilization) consequences of CO 2 intrusion in these systems. Current knowledge gaps, including the role of CO 2 -induced changes in redox conditions, the influence of CO 2 influx rate, gas composition, organic matter content and microorganisms are discussed in terms of their potential influence on pertinent geochemical processes and the potential for beneficial or deleterious outcomes.Geochemical modeling was used to systematically highlight why closing these knowledge gaps are pivotal. A framework for studying and assessing consequences associated with each factor is also presented in Section 5.6. v

“…Possible differences between outcrop samples and the reservoir at depth must be taken into consideration. According to [10], at the rock matrix scale there is a predictable reduction in the pore structure with depth owing to the effects of compaction and/or cementation, primarily as quartz overgrowths. Nevertheless, at the rock massif scale, the porosity is expected to increase due to the presence of large scale fractures.…”

Abstract:The aim of this article is to provide a qualitative and quantitative description of Lower-Upper Cretaceous detrital rocks (Escucha and Utrillas sandstones) in order to explore their potential use as CO 2 reservoirs based on their petrographic and petrophysical characteristics. Optical microscopy (OpM) and scanning electron microscopy (SEM) aided by optical image analysis (OIA) were used to get qualitative and quantitative information about mineralogy, texture and pore network structure. Complementary analyses by X-ray fluorescence (XRF) and X-ray diffraction (XRD) were performed to refine the mineralogical information and to obtain whole rock geochemical data. Furthermore, mercury injection capillary pressure analysis (MICP), the gas permeameter test (GPT) and the hydraulic test (HT) were applied to assess the potential storage capacity and the facility of fluid flow through the rocks. Both of these factors have an outstanding importance in the determination of CO 2 reservoir potential. The applied petrophysical and petrographic methods allowed an exhaustive characterization of the samples and a preliminary assessment of their potential as a CO 2 reservoir. The studied conglomerates and sandstones have a porosity range of 8-26% with a dominant pore size range of 80-500 µm. The grain skeleton consists of quartz (95%), very minor potassium feldspars (orthoclase) and a small amount of mica (muscovite and chlorite). According to these preliminary results, among the studied varieties, the Escucha sandstones have the most favorable properties for CO 2 geological storage at the rock matrix scale.
