Underground Hydrogen Storage (UHS) is an emerging large-scale energy storage technology. Researchers are investigating its feasibility and performance, including injectivity, productivity, capacity through numerical simulations. However, several ad-hoc relative permeability capillary pressure functions have been used in the literature, with no direct link to underlying physics of hydrogen production process. Recent measurements for hydrogen-brine system show very low strong liquid phase hysteresis, different what has observed other fluid systems same rock type. This raises concern as extend existing studies literature able reliably quantify potential projects. In this study, we investigate how experimentally measured hysteresis affects performance UHS projects reservoir Relative data during a hydrogen-water core-flooding experiment within ADMIRE project design model.
