Numerical study on hydrogen–geothermal co–production in multi–well hydraulically fractured peridotite formations

Numerical simulation results obtained from the thermo–hydro–chemical (THC) coupled model. The dataset includes: • Model validation data (e.g., production temperature comparison, reaction kinetics, and porosity evolution) • Hydrogen production rate over time • Temperature evolution along fractures • Pressure distribution • Hydrogen concentration • Results under different well patterns and fracture configurations
