Topic Information

Dear Colleagues,

Carbon capture and storage (CCS) is essential to mitigating climate change by isolating and storing CO₂ from industrial emissions. Geochemical studies focus on the long-term integrity of storage sites, examining reactions between injected CO₂ (pure or impure with SO₂, NO, O₂) and host rocks. Key research areas include the following: (1) mineral transformations in reservoir and caprocks (e.g., sandstones, mudstones) and their impact on seal effectiveness; (2) metal mobilization and fines migration induced by CO₂–fluid–rock interactions and their impact on groundwater chemistry ; (3) pore characterization and modelling to allow determination of trapping mechanisms and capacity; and (4) multi-tracer approaches to monitor groundwater flow and geochemical baselines. Field studies (e.g., Surat Basin) and core analyses (e.g., rock geochemistry, QEMSCAN mineralogy, PTX rock reactivity experiments) provide the inputs for reaction path modelling and reactive transport modelling, guiding site selection, and risk assessment. Impurities in CO₂ streams exacerbate geochemical reactivity, necessitating integrated models to optimize secure, permanent sequestration. This Topic seeks original research contributions that advance CCS/CCUS geochemistry through scientific and engineering innovation.

Carbon-based material adsorption is one of the research hotspots in the Carbon Capture, Utilization, and Storage (CCUS) field, and its surface functional groups have a significant impact on CO₂ adsorption performance. This study uses Density Functional Theory (DFT) methods to explore the adsorption mechanism of CO₂ on the surface of carbon-based materials by examining changes in parameters such as adsorption energy before and after the reaction process. It also studies the influence of different functional groups on the surface of carbon-based materials on CO₂ adsorption performance. Research shows that under different doping conditions, the adsorption energy of CO₂ on carbon-based materials can be roughly divided into three levels: when both C=C and C=O double bonds are formed, the adsorption energy reaches the highest level; the structure with the C–N single bond accompanied by the C=O double bond reduces the adsorption energy by one level; and when only C=C double bonds exist, the adsorption energy is at the lowest level. Meanwhile, the incorporation of functional groups such as N, NH⁺ and O₂ will reduce the adsorption energy of carbon-based materials for CO₂ to varying degrees. Notably, N and NH⁺ modification not only introduces new nitrogen active sites but also optimizes material performance while maintaining a relatively high adsorption capacity, thus demonstrating good modification potential.

Detailed geochemical modelling of the potential groundwater impacts of CO₂ geo-sequestration requires site-specific knowledge of how mobile elements are hosted within rocks. We present a simple sequential extraction procedure analogous to pH conditions produced by different partial pressures of carbon dioxide (CO₂) in contact with water. The procedure consists of three sequential steps: water at pH 7; acetic acid–ammonium acetate at pH 5 and then at pH 3, with the amounts of specific elements extracted by each step considered with respect to the whole rock total element abundance. Our purpose in developing this procedure is three-fold: (1) identify readily mobilized suites of elements for groundwater baseline and monitor bore studies; (2) provide insights regarding the mode/s of occurrence of easily extracted elements within rock samples; and (3) suggest possible mechanisms for the mobilization of rock-sourced elements into groundwater under neutral to moderately acidic pH that can inform the reactive transport modelling of carbon storage sites. In our case study, the second step extracted most of the main mobile elements of interest. Full article
