Abstract The formulation of the hydrogen thermodynamics and behavior are incorporated into mass, momentum, energy conservation equations to determine conditions reserves in subsurface storage salt caverns coupled with inflow outflow through loading/unloading wells. cavern is treated like a leaky tank having permeable conductive walls allowing heat transfer gas leakage interlayer formations, cracks fractures created by thermal stress variation during processes. numerical solution set differential forming dynamic thermo-hydraulic mathematical model subject prescribed initial boundary facilitated temperature, pressure, flow, accumulation/depletion as functions time loading, storage, unloading. This allows an effective inventory analysis caverns. paper provides relevant relationships important theoretical background formulations required for development large-scale simulators which can be applied designing, optimizing, controlling, management, processes large caverns, practical view concept tank, description at different levels sophistication, rigorous governing pressure temperature conditions, demonstration application simplified macroscopic model.

China’s renewable energy sector is experiencing rapid growth, yet its inherent intermittency creating significant challenges for balancing power supply and demand. Power-to-gas (PtG) technology, which converts surplus electricity into combustible gas, offers a promising solution. Salt caverns, due to their favorable geological properties, are among the best choices large-scale underground storage in PtG systems. CO2 leakage along interlayer salt rock–interlayer interfaces key constraint on tightness of subsurface caverns. This paper focuses critical issue within cavern storage, particularly Jintan region. A coupled hydro-mechanics mathematical model developed investigate transportation bedded with variables such as permeability range, pore pressure evolution, changes being analyzed. The results reveal that plays decisive role determining rate extent rock layer. Notably, influence range mudstone significantly larger than those over same period. However, prolonged time, increase both exhibit decreasing trend, eventually stabilizing front reaches boundary simulation domain. Furthermore, elevated operating markedly expands higher cumulative leakage. For specific cavern, can reach up 142 m, volume 522.5 tonnes during 35 years operation. Therefore, setting operational should fully consider mechanical strength interlayer. These findings provide valuable insights optimizing sealing performance systems under varying conditions.
