Geochemical modeling of H2 storage in a sandstone reservoir: Sensitivity analysis of abiotic H2S and CO2 gas formation

Hydrogen storage in geologic reservoirs is a promising technology for storing surplus renewable energy, but the H2 gas quality may be compromised by fluid-rock-gas interactions. Using redox-decoupled, kinetically-controlled, abiotic 0D batch models, this study simulates the 30-year geochemical evolu
