Simulation of the inelastic deformation of porous reservoirs under cyclic loading relevant for underground hydrogen storage.

Subsurface geological formations can be utilized to safely store large-scale (TWh) renewable energy in the form of green gases such as hydrogen. Successful implementation of this technology involves estimating feasible storage sites, including rigorous mechanical safety analyses. Geological formations are often highly heterogeneous and entail complex nonlinear inelastic rock deformation physics when utilized for cyclic energy storage.

Geomechanical simulation of energy storage in salt formations.

A promising option for storing large-scale quantities of green gases (e.g., hydrogen) is in subsurface rock salt caverns.
