Deep saline aquifers have received much attention as storage sites of CO2 due to their large capacity. However, many issues like leakage, low solubility in brine, contamination groundwater with CO2, injectivity impairment, corrosion the pipeline, salt precipitation, and pore plugging are still unresolved. When supercritical is injected into aquifer, its lower density causes it migrate aquifer's top, leaving portion aquifer unswept. At interface between free part slowly dissolves developing a saturated brine on top brine. The difference triggers slow density-driven convection process within aquifer. Researchers extensively investigated these challenges associated explored various techniques improve security. These include injection water-based fluid, surfactants, polymer, nanoparticles or CO2. Despite reported success stories techniques, some limitations stand way full-scale deployment. cost injectants, toxicity, adsorption, plugging. Currently, there scarcity comprehensive reviews that thoroughly analyze methods utilized for aquifers. Hence, primary objective this Review highlight been encountered during provide an overview benefits employed thus far. In addition, carbon capture (CCS) projects face further hurdles space, leakage through wells, high projects, uncertainty evaluation capacity, inaccurate interpretation data. study suggests necessity thorough research address overcome issues.

In-situ CO2 mineralisation has been demonstrated as a rapid and secure mechanism of geological storage through series field demonstrations in Icelandic basalts by Carbfix. A key indicator success the first these tests was discovery newly precipitated calcite on monitoring well downhole pump that contained 14C tracer added to injected CO2. In this study we use clumped, carbon oxygen isotope measurements determine temperature source parental fluids for found pump. Clumped values (Δ47) range from 0.526‰ 0.540‰, which correspond temperatures 45–51 °C. These are 10–16 °C warmer than pre-injection measured at depth. We attribute continuous water pumping well, drawing up waters deeper reservoir Calculated parent fluid (δ18O) match local meteoric records. Calcite (δ13C) conform CarbFix injection source, but higher expected given previously established yields CarbFix. This is likely consequence crystal homogenisation process required analysis, resulting an averaging δ13C values. The results validate previous findings subsurface migration occurred within porous media reservoir. example how isotopic analysis carbonates can contribute verification storage.

Gas fermentation using homoacetogenic consortia to convert CO2 into sustainable fuels and chemicals has emerged as a promising biotechnological route toward carbon neutrality. However, significant challenge is the low gas–liquid mass transfer rates due limited solubility of C1 gases. This study investigates enhancement high-pressure gas (HPGF) reactor embedded with electrodes, effectively overcoming barriers addressing sustainability through an innovative approach. H2 electron donor was conducted in pressurized fermenters (PFs) at varying partial pressures (pCO2-2, -3, -5 bar), while pressured electro-fermentation (PEF) used electrodes replace H2. The pCO2-PEF-5 condition achieved highest acetic acid productivity 2.8 g/L, followed by pCO2-PEF-3 2.65 representing 1.2 1.18 times higher yields than best PFs (pCO2-PF-3, 2.1 g/L), respectively. Additionally, PEF systems enhanced solventogenic activity, ethanol production reaching 1.4 g/L pCO2-PEF-5. substitution improved fixation conversion (pCO2-PEF-5: 67 mg/L/h, 77%), demonstrating viable strategy for conversion. thermodynamic analysis indicated more spontaneous synthesis compared PF systems. Bioelectrochemical assessments revealed charge rates, faradaic efficiency 48% pCO2-PEF-5, further supporting Especially, key genes Wood–Ljungdahl pathway (WLP) were upregulated systems, confirming that influences metabolic pathways favoring solvent production. A life cycle assessment (LCA) highlighted net emission reduction −7 kg equiv PEF-5 lower impact across endpoint categories, highlighting carbon-negative potential this From planetary boundary framework perspective, process operates within Holocene state reducing emissions, helps maintaining biosphere integrity, reduces atmospheric CO2, contributes minimally nitrogen phosphorus flows. signifies scaling processes. integration not only addresses limitations but also enhances productivity.
