“…A thorough understanding of the interaction of CO 2 /brine/rock systems provides useful insights into the factors affecting injectivity and storage permanence . Experimental and modeling studies to investigate changes in host rock properties when exposed to CO 2 have been conducted . The specifics of the changes are dependent upon rock composition, rock/water ratio, reactive surface area/mass transfer phenomena, and the progressive dissolution of CO 2 in the brine that decreases the pH .…”

Saline aquifers are the largest potential continental geologic CO2 sequestration resource. Understanding of potential geochemically induced changes to the porosity and permeability of host CO2 storage and sealing formation rock will improve our ability to predict CO2 plume dynamics, storage capacity, and long‐term reservoir behavior. Experiments exploring geochemical interactions of CO2/brine/rock on saline formations under CO2 sequestration conditions were conducted in a static system. Chemical interactions in core samples from the Lower Tuscaloosa formation from Jackson County, Mississippi, with exposure to CO2‐saturated brine under sequestration conditions were studied through six months of batch exposure. The experimental conditions to which the core samples of Lower Tuscaloosa sandstone and Selma chalk were exposed to a temperature of 85°C, CO2 pressure of 23.8 MPa (3500 psig), while immersed in a model brine representative of Tuscaloosa Basin. Computed tomography (CT), X‐Ray diffraction (XRD), Scanning Electron Microscopy (SEM), brine chemistry, and petrography analyses were performed before and after the exposure. Permeability measurements from the sandstone core sample before and after exposure showed a permeability reduction. No significant change of the permeability measurements was noticed for the core sample obtained from Selma chalk after it was exposed to CO2/brine for six months. These results have implications for performance of the storage interval, and the integrity of the seal in a CO2 storage setting. © 2016 Society of Chemical Industry and John Wiley & Sons, Ltd

“…The captured CO 2 can be pressurized and stored in geological formations underground such as deep ocean (Phelps et al, 2015), saline aquifers (Soong et al, 2014;Yang et al, 2014), unminable coal beds (Kieke et al, 2009), and depleted oil/gas reservoirs (Olajire, 2014). With widespread geographic distribution, CO 2 injection into confined geological formations offers a potentially large storage capacity (IPCC, 2007).…”

This paper provides an overview of state-of-the-art carbon fixation and utilization technologies. Several carbon capture processes, such as chemical absorption and chemical looping, are reviewed and illustrated. In addition, various types of chemicals and fuels that can be produced using concentrated CO 2 (or other forms) through physical, chemical, or enhanced biological methods are presented. Among those carbon conversion methods, two promising approaches, i.e., microalgae ponds and accelerated carbonation using alkaline solid wastes, are reviewed in detail. Microalgae are fast-growing and ubiquitous photosynthetic organisms, which are rich in protein and can be converted to biodiesel fuel. They have been recognized as an alternative feedstock not only because they use CO 2 from the atmosphere but also due to their high lipid content per biomass compared to other plants. In this study, for the microalgae technologies, the principles and applications of open pond systems are discussed in terms of both technological and economic considerations. The important operation parameters affecting productivity of microalgae, including light intensity, temperature, mixing, CO 2 delivery, accumulation of dissolved oxygen, and salinity are summarized. On the other hand, accelerated carbonation technologies are an attractive and feasible approach to integrating alkaline solid waste treatment with CO 2 fixation and utilization. In this study, the performance of various carbonation processes is critically reviewed from the perspectives of process design, energy consumption, and environmental benefits. The carbonated solid product can also be used as supplementary cementitious materials in a blended cement or concrete block. Accordingly, the performance of cement pastes with carbonated product, in terms of workability and strength development, are evaluated from the cement chemistry point of view. Cement manufacturing is an energy and material intensive process, with high annual production. It is noted that, through the accelerated carbonation process, significant indirect environmental benefits can be realized.

“…In addition to EOR, there are growing interests in CCS in saline aquifers due to their large potential storage capacities (Soong et al, 2014). As such, several projects were in the pipeline demonstrating its viability (Leung et al, 2014).…”

“…With regard to the release and mobility of trace elements associated with CCS, most tests were conducted at the batch and column scales (Little and Jackson, 2010;Lu et al, 2010;Soong et al, 2014). Leaching tests were conducted to study and assess the mechanisms and efficiency of metal release processes from solids in contact with liquids to simulate the consequences of CO 2 leakages from CCS (Ardelan and Steinnes, 2010;de Orte et al, 2014).…”

Excess carbon dioxide emission was considered as the most important cause of increased trend of global warming. Significant amounts of research were devoted to the reduction of CO 2 emission and CO 2 sequestration. Sequestration of CO 2 in empty oil reservoirs was considered as one of the most promising options. However, the effects of metal release and mobility as a result of CO 2 injection were not studied in detail, particularly under super-critical CO 2 (scCO 2 ) conditions. In this study, the release of selected metals immersed in distilled water for varying amounts of time in the absence and presence of scCO 2 was assessed in simulated conditions at 90°C and 24 MPa. Significant increases in dissolution of Fe, Sr, and Ba by 3, 8, and 24 times were found when the storage rock sandstone or caprock shale was immersed in DI water for different time period. However, in the presence of scCO 2 , the dissolution of these metals was reduced by 80% for Fe, suggesting permanent sequestration of scCO 2 into carbonate minerals. The trend in changes of pore water chemistry in the sandstone and shale after being immersed in DI water showed dissolution of Sr-bearing mineral and precipitation of Ba-bearing mineral.
