As subsurface hydrogen storage gains attention as a critical element of the energy transition, GEOS provides the multiphysics framework needed to model hydrogen injection and withdrawal cycles.

Key Capabilities

  • Multiphase flow with hydrogen-specific equations of state
  • Depleted reservoir and aquifer storage modeling
  • Geomechanical cycling effects during injection/withdrawal
  • Cushion gas optimization

Storage Integrity

GEOS models the coupled thermo-hydro-mechanical processes that govern storage integrity under cyclic loading conditions. This includes salt creep and cavern convergence for salt storage, and caprock integrity for porous media storage.

Hydrogen-Specific Challenges

Hydrogen’s low viscosity, high diffusivity, and potential for microbial consumption and geochemical reactions introduce unique modeling challenges compared to natural gas storage.
