Geological H2 storage plays a central role to enable the successful transition renewable economy and achieve net-zero emission in atmosphere. Depleted oil gas reservoirs are already explored with extensive reservoir operational data. However, residual hydrocarbons can mix injected reservoirs. Furthermore, low density high diffusivity of may establish leakage from via fault pathways. Interestingly, be consumed by microorganisms, which results pore-network precipitation, plugging, partial permeability impairment. Therefore, stored lost formations if scenario is not planned cautiously. While salt caverns safe commercially proven geo-rock for storage, they have low-storage capacity compared depleted Moreover, structures (e.g., domel, bedded) microorganisms activities cavern limiting factors, influence process. Accordingly, we discuss challenges future perspectives hydrogen different geological settings. We also highlight geographical limitations diverse microbial communities theoretical understanding abiotic transformation (in terms rock's minerals, i.e., mica calcite) storage. Regarding fundamental behavior settings, it less soluble formation water; therefore, solubility trapping CO2 CH4. could attain higher capillary entrance pressures porous media over CH4 due interfacial tension. Additionally, viscosity facilitate its injection production but secondary viscous fingering. Thus, this review documents blend key information amendment subsurface at industrial scale.

Gas transportation is of significance, especially in carbon dioxide sequestration and successful performances enhanced methane recovery from shale layers. Among the three primary mechanisms for gas phase layers, diffusion considered as most important phenomenon. The main objective this comprehensive study to propose a mathematical model unipore modified consider kinetic adsorption two different samples at pressure ranges. To validate accuracy model, experimental investigations such ranges 3.2–9.3 MPa 2.5–6.5 were performed compare with results proposed model. kinetics analysis indicated that required time completion fractional uptake process about 4–13 min, whereas it takes approximately 5–17 min reach 70% both samples.

Abstract Clays and clay minerals dissolve over a broad pH range, such as during sediment diagenesis in variety of applications, including nuclear waste storage, landfills, geopolymer binders the construction industry. The solubility depends on process parameters (pH, temperature, pressure, etc.) material properties (phase content, mineral composition, particle size, etc.). Pretreatments calcination or severe grinding change could enhance solubility, which is called activation. aim current study was to determine three different after (metakaolinite, metamontmorillonite, metaillite) high molar alkaline solutions (NaOH) up 10.79 mol/L = 14.73. Furthermore, an Al(OH) 3 powder solution analyzed, it can be used adjust Si:Al ratio precursors. residues treatment were investigated disclose potential alterations their phase contents. Based results thermal activation, conclusions about suitability precursors made. All showed increase proportional concentration solution. decreased order metakaolinite > metamontmorillonite metaillite. Thereby, dissolution incomplete for all (<90%) 7 days congruent metaillite but incongruent metamontmorillonite.
