Underground porous formations provide significant storage capacity for H2 and CO2, making them a promising solution to aid energy needs mitigate CO2 emissions. The interfacial tension (IFT) of H2–brine within the underground formations, along with H2–H2O–rock wettability, is crucial factor in determining efficiency hydrogen (UHS). Cushion gas normally preinjected maintain reservoir pressure, prevent migration into rock matrix, control both injectivity productivity. Hereby, we examined influence CH4 as cushion gases at different temperatures, pressures, salinity conditions on IFT water–H2–rock wettability. We employed molecular dynamics (MD) simulations confronted our results against experimentally reported data literature. In addition, have assessed interfaces confined slit nanopore relevant calcite silica formations. Our reveal that brine–H2 interface not significantly sensitive pressure. However, increasing temperature reduced H2–brine, contrast increases IFT. (CH4 CO2) reduce when mixed hydrogen, having more pronounced effect than across all salinities. Such an impact due strong water–CO2 interactions compared water–CH4 water–H2 interactions. Both (CO2 CH4) could perturb surface hydrations maintaining zero-contact angle except low pH sandstone Calcite their water-wet state temperature, salinity. sandstone, predicted intermediate very good agreement experimental data. capillary pressure maps are built visualize wettability flow, mechanism, caprock sealing efficiency. pointed out be potential while (at acidic pH), using might lead loss matrix.
