“…This means that pressure in the receiving formation increases over a large area, and existing brines are displaced away from the injection site (79). Thus, pressure build-up limits practical storage capacity in many cases (80,81), which has spurred development of pressure management concepts generally (82), and brine withdrawal plans at the Australian Gorgon sequestration project specifically (83). Regulations also recognize the novel aspects of sequestration, typically requiring thorough understanding of site-specific risks (84), which has driven much research into the potential impacts of CO 2 sequestration and risk assessment (85,86).…”

We review future global demand for electricity and major technologies positioned to supply it with minimal greenhouse gas (GHG) emissions: renewables (wind, solar, water, geothermal, and biomass), nuclear fission, and fossil power with CO2 capture and sequestration. We discuss two breakthrough technologies (space solar power and nuclear fusion) as exciting but uncertain additional options for low-net GHG emissions (i.e., low-carbon) electricity generation. In addition, we discuss grid integration technologies (monitoring and forecasting of transmission and distribution systems, demand-side load management, energy storage, and load balancing with low-carbon fuel substitutes). For each topic, recent historical trends and future prospects are reviewed, along with technical challenges, costs, and other issues as appropriate. Although no technology represents an ideal solution, their strengths can be enhanced by deployment in combination, along with grid integration that forms a critical set of enabling technologies to assure a reliable and robust future low-carbon electricity system.

“…This contrasts with far lower (or approximately zero) costs of passive pressure management, where the pressure is allowed to normalize through natural migration of the in situ fluids out of the reservoir, the slow dissolution of the CO 2 into those fluids, or some other natural mechanism. If active pressure management is necessary but the costs of this important method of risk mitigation are prohibitive, then a substantial portion of the technically accessible storage resource (TASR) may not meet economic feasibility criteria for CO 2 storage capacity under current regulations (Schrag 2009;Birkholzer et al 2012Birkholzer et al , 2015Breunig et al 2013;Heidug 2013;Cihan et al 2014;Bachu 2015;Pawar et al 2015).…”

“…In these extensive geologic formations, residual trapping could be the most relevant mechanism for immobilizing CO 2 , at least in the short term (tens to hundreds of years). Solubility trapping may play an increasing role in the long run (over hundreds of years or longer), but may not add significantly to current estimates of storage capacities (Lu et al 2013;Bachu 2015). Residual trapping occurs when droplets of CO 2 are immobilized by capillary forces and remain trapped in the tight pore spaces of the rock as the plume of injected CO 2 passes through (Brennan et al 2010).…”

“…If a fault that accesses the basement is more of a risk concern for induced seismicity than one that extends from the storage formation up into the caprock (and beyond), then injecting CO 2 at a shallower depth within a DSF could pose relatively lower overall risk . In that case, however, decision makers may have to weigh the benefit of decreasing the risk of induced seismicity against the costs of reduced storage efficiency related to CO 2 only occupying the upper reaches of the reservoir (Bachu 2015).…”

Given a scarcity of commercial-scale carbon capture and storage (CCS) projects, there is a great deal of uncertainty in the risks, liability, and their cost implications for geologic storage of carbon dioxide (CO 2 ). The probabilities of leakage and the risk of induced seismicity could be remote, but the volume of geologic CO 2 storage (GCS) projected to be necessary to have a significant impact on increasing CO 2 concentrations in the atmosphere is far greater than the volumes of CO 2 injected thus far. National-level estimates of the technically accessible CO 2 storage resource (TASR) onshore in the United States are on the order of thousands of gigatons of CO 2 storage capacity, but such estimates generally assume away any pressure management issues. Pressure buildup in the storage reservoir is expected to be a primary source of risk associated with CO 2 storage, and only a fraction of the theoretical TASR could be available unless the storage operator extracts the saltwater brines or other formation fluids that are already present in the geologic pore space targeted for CO 2 storage. Institutions, legislation, and processes to manage the risk, liability, and economic issues with CO 2 storage in the United States are beginning to emerge, but will need to progress further in order to allow a commercial-scale CO 2 storage industry to develop in the country. The combination of economic tradeoffs, property rights definitions, liability issues, and risk considerations suggests that CO 2 storage offshore of the United States may be more feasible than onshore, especially during the current (early) stages of industry development.

“…The Carbon Sequestration Leadership Forum (CSLF) and US Department of Energy (USDOE) both proposed the standards and methodologies for CO 2 storage capacity estimation and site selection and also the atlas [4][5][6][7][8][9], which provided the basic methodologies. Some researchers developed the methodologies or key parameters to evaluate the CO 2 storage potential or site selection [10,11], and Goodman et al [12] provided a detailed description of the USDOE's methodology for CO 2 storage potential evaluation. In China, Zhang et al [13] first carried out a preliminary assessment of the national scale potential of CO 2 geological storage 2 Geofluids in depleted oil and gas fields, unmineable coal seams, and deep saline aquifers.…”

Mesoscale Assessment of CO₂ Storage Potential and Geological Suitability for Target Area Selection in the Sichuan Basin

et al. 2017

In China, south of the Yangtze River, there are a large number of carbon sources, while the Sichuan Basin is the largest sedimentary basin; it makes sense to select the targets for CO 2 geological storage (CGUS) early demonstration. For CO 2 enhanced oil and gas, coal bed methane recovery (CO 2 -EOR, EGR, and ECBM), or storage in these depleted fields, the existing oil, gas fields, or coal seams could be the target areas in the mesoscale. This paper proposed a methodology of GIS superimposed multisource information assessment of geological suitability for CO 2 enhanced water recovery (CO 2 -EWR) or only storage in deep saline aquifers. The potential per unit area of deep saline aquifers CO 2 storage in Central Sichuan is generally greater than 50 × 10 4 t/km 2 at P50 probability level, with Xujiahe group being the main reservoir. CO 2 storage potential of depleted gas fields is 53.73 × 10 8 t, while it is 33.85 × 10 8 t by using CO 2 -EGR technology. This paper recommended that early implementation of CGUS could be carried out in the deep saline aquifers and depleted gas fields in the Sichuan Basin, especially that of the latter because of excellent traps, rich geological data, and well-run infrastructures.
