PhD position: Numerical and experimental approaches on the behavior of salt caverns during storage of hydrogen and other gases

PhD opportunity at the École des Mines de Paris – Centre des Géosciences – Fontainebleau

This proposed PhD thesis is dedicated to investigate the integrity of salt cavern mechanical and thermodynamic behavior during fast and slow cycling while addressing the entire complexity of the Computational Fluid Dynamics (CFD) problem, i.e. full discretization of the cavern, gas cavern velocity and thermodynamic variables spatial variations, nature of flow, and the 3D thermo-hydro-mechanical behavior of salt. Moreover, the problem of H2O storage in salt caverns is particular from other gases. This is attributed to the large mobility of hydrogen induced by its very small molecular length, and its potential reactivity with other chemical species that can be present in the storage environment. We aspire that this PhD thesis would shed a light on the phenomenon of hydrogen seepage into the salt rock during fast and slow cycling.
