“…Continued reliance on carbon intensive energy sources to sustain global economies is creating an international urgency to develop strategies and technologies to manage greenhouse gas emissions . In geologic carbon sequestration (GCS), CO 2 is captured and pumped as a fluid deep into underground rock formations where it (1) is contained by a low permeability caprock, (2) dissolves into formation waters, and in some cases (3) reacts with host rock to form solid carbonates in a process called mineral trapping. , Reservoirs that are best suited for mineral trapping are those in volcanic flood basalts, a rock type dominating certain provincial domains in the CO 2 producing countries of the United States, India, and China. − In the basalt–CO 2 –H 2 O system, mineral trapping occurs through dissolution of primary components (i.e., plagioclase, pyroxene, olivine, and glassy mesostasis), which releases divalent cations (Mg 2+ , Ca 2+ , and Fe 2+ ) that react with CO 2 rich fluids to precipitate stable carbonate minerals. Subsurface conditions in GCS dictate that injected carbon dioxide will be supercritical (scCO 2 ) and initially reside in pore spaces in two-phase equilibrium with variable amounts of incompletely displaced remaining water.…”

Continental flood basalts are attractive formations for geologic sequestration of carbon dioxide because of their reactive divalent-cation containing silicates, such as forsterite (Mg2SiO4), suitable for long-term trapping of CO2 mineralized as metal carbonates. The goal of this study was to investigate at a molecular level the carbonation products formed during the reaction of forsterite with supercritical CO2 (scCO2) as a function of the concentration of H2O adsorbed to the forsterite surface. Experiments were performed at 50 °C and 90 bar using an in situ IR titration capability, and postreaction samples were examined by ex situ techniques, including scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), focused ion beam transmission electron microscopy (FIB-TEM), thermal gravimetric analysis mass spectrometry (TGA-MS), and magic angle spinning nuclear magnetic resonance (MAS NMR). Carbonation products and reaction extents varied greatly with adsorbed H2O. We show for the first time evidence of Mg-carbonate surface complexation under wet scCO2 conditions. Carbonate is found to be coordinated to Mg at the forsterite surface in a predominately bidentate fashion at adsorbed H2O concentrations below 27 μmol/m(2). Above this concentration and up to 76 μmol/m(2), monodentate coordinated complexes become dominant. Beyond a threshold adsorbed H2O concentration of 76 μmol/m(2), crystalline carbonates continuously precipitate as magnesite, and the particles that form are hundreds of times larger than the estimated thicknesses of the adsorbed water films of about 7 to 15 Å. At an applied level, these results suggest that mineral carbonation in scCO2 dominated fluids near the wellbore and adjacent to caprocks will be insignificant and limited to surface complexation, unless adsorbed H2O concentrations are high enough to promote crystalline carbonate formation. At a fundamental level, the surface complexes and their dependence on adsorbed H2O concentration give insights regarding forsterite dissolution processes and magnesite nucleation and growth.

“…The feasibility of geologic CO 2 sequestration (GCS) in basaltic rocks has been investigated primarily through experimental methods (Peuble et al, 2015;Galeczka et al, 2014;Stefánsson, 2012a, 2012b;McGrail et al, 2006;Rosenbauer et al, 2012;Schaef and McGrail, 2009;Schaef et al, 2010) and, to a lesser extent, via natural analogues (Flaathen et al, 2009;Lu et al, 2011) and pilot projects (Alfredsson et al, 2013;Gislason et al, 2010;Matter et al, 2011;McGrail et al, 2011). These studies have focused on the reactivity of CO 2 with fresh, unaltered olivine-rich material, basalt and basaltic glass.…”

Geochemistry of CO2-rich waters in Iceland

et al. 2016

CO 2 -rich waters in Iceland from volcanic systems of the Mid-Atlantic Ridge and off-rift volcanic areas of Iceland provide insights into the interactions between CO 2 -rich fluids and basaltic crust.These waters, from the Snaefellsnes Peninsula, within the South Iceland Seismic Zone and on the margin of the Torfajökull central volcano, are chemically and isotopically distinct from surface waters, groundwaters and low and high-temperature geothermal fluids in Iceland. Our conceptual model for the evolution of thermal and non-thermal CO 2 -rich waters (~4-80 mmol/kg ΣCO 2 (aq); 6.6-192 °C) suggests that lower subsurface temperatures during retrograde alteration and cooling of a geothermal system increase the aqueous solubility of CO 2 , which allows anomalously high aqueous CO 2 concentrations. The elevated CO 2 concentrations result in slightly acidic pH (average in situ pH of 6.40), which leads to increased dissolution of primary and hydrothermal silicate minerals. Equilibrium with respect to carbonate minerals, calculated using measured solute concentrations, suggests that carbonate mineral reactions control the water compositions in these systems more than in high-temperature systems, and that hydrothermally altered basalts are sufficiently reactive to promote carbonate mineralization during geologic CO 2 sequestration (GCS). Water-rock interaction with previously hydrothermally altered basalts releases trace elements to the aqueous phase to levels above the World Health Organization drinking water limit. The elements of environmental concern include arsenic (<0.01 to 1.08 μmol/kg) and manganese (<0.1 to 184 μmol/kg), highlighting the need for careful site selection during GCS to prevent groundwater contamination.

“…To obtain the unique environmental parameters of the storage sites, geochemical and hydrogeological modeling has been considered essential as it can provide comprehensive knowledge about long-term interactions, such as aluminosilicates' dissolution/precipitation [13], the behavior of minerals, their distributions and abundance, the effect of the relevant geological factors, and the impurity of injected CO 2 on its storage performance. Recently, the simulation of CO 2rock-brine interactions has been implemented in several research projects and studies [14][15][16][17][18][19]. PHREEQC v3 has been widely used for reactive transport modeling (RTM).…”

This study investigated the reactive transport modeling of CO2 injection into the Kazakhstan reservoir to identify mineralogical and porosity changes due to geochemical reactions. Additionally, sensitivity analysis was performed to test the effect of the surface area and gas impurity on the CO2 storage capability. Despite the current need to investigate carbon sequestration in Kazakhstan, a limited number of studies have been conducted in this field. The Ebeity oil reservoir sandstone formation in the Pre-Caspian Basin has been tested as a potential CO2 storage site. The 1D PHREEQC simulation results of 10,000 years suggest that reservoirs with a higher abundance of these secondary carbonates may be better suited for long-term CO2 sequestration. The concentration of Fe3+ fluctuated, influenced by magnetite and siderite dissolution, leading to ankerite precipitation at 20 and 40 m. The porosity increased from 15% to 18.2% at 1 m and 20 m, favoring a higher CO2 storage capacity, while at 40 m, it remained stable due to minor mineral alterations. A reduced surface area significantly limits the formation of dawsonite, a crucial secondary mineral for CO2 trapping. For instance, at λ = 0.001, dawsonite formation dropped to 6 mol/kgw compared to 24 mol/kgw at λ = 1. Overall, the results of this study can play an essential role in future geological analyses to develop CO2 storage in Kazakhstan for nearby reservoirs with similar geological characteristics.
