“…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.

“…Additional assumptions made by this model include: 1) Aquifers exhibit horizontal flow; 2) Capillary pressure is negligible resulting in a sharp fluid interface; 3) CO 2 plume thickness at any given location is assumed to be the maximum plume thickness from all sources in the aquifer; 4) Pressure response from sources and sinks are superimposed in each aquifer; and 5) the injectivity of the formation remains constant. Several of these processes are important [9,11,13,15,17,22,26] and should be included [6,16,23,39] when model accuracy is more important that efficiency (e.g. during final project design).…”

Successful large-scale implementation of geological CO 2 sequestration (GCS) will require the preliminary assessment of multiple potential injection sites. Risk assessment and optimization tools used in this effort typically require large numbers of simulations. This makes it important to choose the appropriate level of complexity when selecting the type of simulation model. A promising multiphase semi-analytical method proposed by [40] to estimate key system attributes (i.e. pressure distribution, CO 2 plume extent, and fluid migration) has been found to reduce computational run times by three orders of magnitude when compared to other standard numerical techniques. The premise of the work presented herein is that the existing semi-analytically leakage algorithm proposed by [40] may be further improved in computational efficiency by applying a fixed point type iterative global pressure solution to eliminate the need to solve large sets of linear equations at each time step. Results show that significant gains in computational efficiency are obtained with this new methodology. In addition, this modification provides the same enhancement to similar semi-analytical algorithms that simulate singe-phase injection into multi-layer domains.

“…Previous studies and applications show that CO 2 injectivity can be affected by the following mechanisms: (1) pressure build-up due to massive and continuous CO 2 injection; (2) dry-out of the near-well zone due to evaporation of H 2 O into unsaturated CO 2 ; (3) CO 2 -water-rock interactions induced by the injection of CO 2 (Bacci et al 2011) [11][12][13]. Among these processes, CO 2 -water-rock interactions could alter the rock matrix and potentially lead to porosity and permeability changes in the near-well zone [14][15][16][17], which is of particular importance for CO 2 injectivity.…”

A 100,000 t/year demonstration project for carbon dioxide (CO 2 ) capture and storage in the deep saline formations of the Ordos Basin, China, has been successfully completed. Field observations suggested that the injectivity increased nearly tenfold after CO 2 injection commenced without substantial pressure build-up. In order to evaluate whether this unique phenomenon could be attributed to geochemical changes, reactive transport modeling was conducted to investigate CO 2 -water-rock interactions and changes in porosity and permeability induced by CO 2 injection. The results indicated that using porosity-permeability relationships that include tortuosity, grain size, and percolation porosity, other than typical Kozeny-Carman porosity-permeability relationship, it is possible to explain the considerable injectivity increase as a consequence of mineral dissolution. These models might be justified in terms of selective dissolution along flow paths and by dissolution or migration of plugging fines. In terms of geochemical changes, dolomite dissolution is the largest source of porosity increase. Formation physical properties such as temperature, pressure, and brine salinity were found to have modest effects on mineral dissolution and precipitation. Results from this study could have practical implications for a successful CO 2 injection and enhanced oil/gas/geothermal production in low-permeability formations, potentially providing a new basis for screening of storage sites and reservoirs.
