“…Therefore, both processes are enhanced by reducing the particle size. This also explains why both CO 2 aqueous solution and scCO 2 experiments try to minimize the particle size, and even use artificial synthesis methods to prepare nanomagnesium olivine crystals for mineralization. , On the other hand, there are many rock minerals available for CO 2 mineralization research, such as basalt, peridotite, , plagioclase, potassium feldspar, basaltic glass, serpentine, olivine, pyroxene, wollastonite and many other minerals, which are all silicate ores rich in Ca 2+ or Mg 2+ . However, the content of Ca 2+ or Mg 2+ varies greatly among them .…”

CO 2 mineralization is a safe and stable geological sequestration method that plays an important role in reducing and mitigating global carbon emission. Currently, the Carbfix project in Iceland and the Wallula project in the United States represent two different mineralization sequestration modes of CO 2 aqueous solution and wet supercritical CO 2 . In the microscopic process, the main difference between the two is that the CO 2 aqueous solution follows the dissolution−precipitation theory, and wet scCO 2 follows the adsorption−complexation process. We verified the changes of the components before and after mineralization as well as the evolution of the morphology and structure through different characterization methods and established three mineralization models. Furthermore, starting from the chemical reaction mechanism of the two methods, we modified the crystallization kinetics Avrami equation, and obtained the theoretical law of the mineralization rate under different conditions. Eventually, the effects of temperature, pressure, ore size and type, additives and water content on the mineralization efficiency were further explored. This paper discusses the various challenges to mineralization sequestration and its potential opportunities, especially in the field of biomineralization. These results are important for understanding the mechanism of CO 2 mineralization under geological conditions and proposing a potential strategy for the enhancement of sequestration efficiency.

“…These silicate minerals neutralize acids and provide the necessary raw materials for precipitation by providing Ca 2+ , Mg 2+ , and Fe 2+ . Consequently, achieving effective carbonation of natural silicate minerals is most feasible in porous minerals rich in divalent metal cations, such as basalts and mantle peridotites [61][62][63]. An exemplar of implementation is the Carbon Fix project in Iceland, where carbon dioxide was injected into the ground in the form of carbonated water.…”

The goals of carbon neutrality and peak carbon have officially been proposed; consequently, carbon dioxide utilization and sequestration technology are now in the limelight. Injecting carbon dioxide into reservoirs and solidifying and sequestering it in the form of carbonates after a series of geochemical reactions not only reduces carbon emissions but also prevents carbon dioxide from leaking out of the formation. Carbon dioxide mineralization sequestration, which has good stability, has been considered the best choice for large-scale underground CO2 sequestration. To provide a comprehensive exploration of the research and prospective advancements in CO2 mineralization sequestration within Chinese oil and gas reservoirs, this paper undertakes a thorough review of the mechanisms involved in CO2 mineralization and sequestration. Special attention is given to the advancing front of carbon dioxide mineralization, which is driven by microbial metabolic activities and the presence of carbonic anhydrase within oil and gas reservoirs. The paper presents an in-depth analysis of the catalytic mechanisms, site locations, and structural attributes of carbonic anhydrase that are crucial to the mineralization processes of carbon dioxide. Particular emphasis is placed on delineating the pivotal role of this enzyme in the catalysis of carbon dioxide hydration and the promotion of carbonate mineralization and, ultimately, in the facilitation of efficient, stable sequestration.

“…CO 2 ‐EOR, combined with the in‐place infrastructure and facilities and the structural integrity of an oil reservoir, provides an opportunity for the synergy between the ever‐increasing energy production demands and the requested reduction in anthropogenic CO 2 emission (Farajzadeh et al., 2020). Apart from the well‐recognized underground trapping mechanisms, including structural‐stratigraphic trapping, CO 2 dissolution in formation water and oil, and residual trapping in porous space, CO 2 can also be permanently stored through carbonate mineralization arising from CO 2 ‐water‐rock reactions that convert CO 2 to carbonate minerals (Al Kalbani et al., 2023; Y. Chen et al., 2023; Cui et al., 2017; Farquhar et al., 2015; Raza et al., 2022). The dissolved CO 2 in water generates weak acid that dissociates into H + , HCO 3 − , and CO 3 2− .…”

Geochemical reactions are crucial for in situ CO2 mineralization underground associated with CO2‐enhanced oil recovery (CO2‐EOR) in a hydrocarbon reservoir. However, the presence of formation water and adsorbed oil on rocks generates physical barriers to CO2's access to mineral surfaces, which may yield impedance to CO2 mineral trapping that has yet to be accounted for. In this study, we mimic the dynamic oil detachment process using molecular dynamic (MD) simulation and analyze the influence of an adsorbed oil film on supercritical CO2 (scCO2) diffusion toward the mineral surface in the presence and absence of a water phase. Our results demonstrated a negative impact of water on oil film detachment by scCO2, which may weaken mineral reactions and is unfavorable for mineralized CO2 storage underground.
