Data for: HyUSPRe - Work Package 4 - Hydrogen reservoir flow behaviour: Measurements of molecular diffusion, mechanical dispersion and relative permeability

In working package 4 of the HyUSPRe project three different laboratory measuring methods were used to investigate the flow behaviour of hydrogen in underground pore storages. The first experimental series investigated the molecular diffusion for a binary H2-CH4 system in reservoir rocks. Based on the measurement results effective diffusion coefficients were determined. The second experimental series investigated the mechanical dispersion also for a H2-CH4 system. Here, longitudinal dispersivities were determined. The third experimental series investigated unsteady state relative permeabilities for H2-brine systems. Based on this two-phase relative permeability curves were determined under drainage conditions. The measurements were conducted at a range of temperatures, pressures, salinities and with different storage rock samples. The data set available here allows the reinterpretation and further use of the experimental data. It contains in total 29 molecular diffusion, 13 mechanical dispersion and 9 relative permeability measurements. Further details on the methods, measurement conditions and an interpretation of the results can be found in deliverable 4.4 of the HyUSPRe project.
