Abstract A multi-phase flow experimental setup is introduced to examine the behavior of H2 transport in a brine-saturated core under different rates and regimes context underground hydrogen storage (UHS). Analog fluids decane viscosified brine were used lieu obtain viscosity ratio similar H2-brine at reservoir conditions. normalized finger width was allow for comparison widths between this analog system system. X-ray computed tomography (CT) image during injection compute average saturation across sample, as well measure fingers that formed experiments. The 1D profile fast-flowing experiment showed initially stable displacement before onset viscous fingering, slow-flowing presence distinct from injection, limits imaging. resulting images tests confirm fingering present both tests, but limitations equipment capability suggest there exists minimum can be observed with current setup. This necessitates additional determine evolution fingers, observable.
