There is increasing interest in attainment of a CO2-free global economy and net zero carbon emissions by 2050 to mitigate the negative impact warming unfavorable climate change. However, success large-scale underground H2 CO2 storage depends on rock wetting behavior dynamics gas/brine interfacial tension (IFT), which significantly influences capillary pressure. Previous studies have demonstrated that wettability can be altered into hydrophilic state using surface-active chemicals such as surfactants, nanoparticles, methyl orange, blue. these also showed higher propensity reduce IFT, for residual structural trapping potential host rock. Herein, limestone modification capacity polymeric surfactant (chitosan salt) its impacts CO2/brine H2/brine IFT were evaluated pendant drop technique pressure measurement. Results shifted right presence chitosan salt solutions, indicating reduction needed push water pore spaces This effect increased with concentrations solution from 100 1000 ppm. Specifically, at 200 psi, saturation seawater-saturated cores about 50 70% whereas deionized water-saturated 25 40% ppm concentration. The CO2/water interface H2/water no significant effects tension.

Underground hydrogen storage (UHS) in salt caverns is a sustainable energy solution to reduce global warming. Salt rocks provide an exceptional insulator store natural hydrogen, as they have low porosity and permeability. Nevertheless, the creeping nature hydrogen-induced impact on operational infrastructure threaten integrity of injection/production wells. Furthermore, scarcity UHS initiatives indicates that investigations well remain insufficient. This study strives profoundly detect research gap imperative considerations for preservation projects. The integrates critical characteristics, geomechanical geochemical risks, necessary measurements maintain integrity. casing mechanical failure was found most challenging threat. corrosive erosive effects atoms cement may critically put at risk. also indicated simultaneous temperature creep behavior corrosion unexplored area has scope further research. inclusive up-to-date source analysis previous advancements, current shortcomings, future requirements preserve implemented within caverns.

Large-scale hydrogen storage is strategically important for society and depleted gas reservoirs have been proposed as a potential solution. However, the mixing with remaining hydrocarbon during injection/production cycles impact of different reservoir parameters on recovery factor (RFH2) not fully understood. We investigate dynamics analyze effects initial factor, permeability, well perforation length, intelligent completion, fractures RFH2. Fine-grid models compositional simulation were used to simulate cyclic storage. Mixing injected occurred in three distinct phases each cycle: 1) displacement through pressure-driven flow injection, 2) density-driven gases idle time after 3) towards production intervals phase. Higher RFH2 s obtained when process was initiated at higher factors. Storing lower permeability also led s, provided pressure limits an issue. In conditions 5× 15× increase moved upward spread laterally, positioning it farther from wellbore. This made more difficult placed zone closer perforations. Shorter lengths top formation resulted best s. Additionally, completions (that closed perforations producing low content) improved by providing possibility purer production.

Abstract Underground hydrogen storage (UHS) is crucial for integrating intermittent renewable energy sources but presents risks from rapid injection-production cycles that cause dynamic pressure changes. These changes can lead to caprock fracturing and fault reactivation, potentially resulting in leakage compromises the security of initiatives. The interaction between different pathways how one activated pathway may influence risk profile subsequent stress fluid distribution another remains poorly understood. This study tackles these questions using coupled flow-geomechanics simulations H2 represent real-world geology well-operation scenarios. For first time, we develop a workflow integrates stress-dependent Barton-Bandis model with Coulomb frictional failure-induced permeability investigate interplay pathways. comprises an injection reservoir, caprock, upper aquifer. When injected into footwall block observe as fracture opening exceeded. Caprock followed by activation leading both along across fault. 15% total gas leaks whereas 10% Although acts conduit movement upwards aquifer, volume only 0.08% gas. However, vertical displacement exhibits clear signatures activation, while shows no significant overall strain or displacement. attributed enhanced lateral constraint on deep layers, imposed model's geometry. In contrast, extending free surface allows greater slip displacement, accommodating deformation.
