Effect of pressure, temperature, and salinity on interfacial tension As represented in (Table S3, supplementary file), pressure and temperature considerably influence the density of water and H2. With increased pressure at a constant temperature, the density values of water and H2 increased, whereas the density of H2 increased significantly. In general, the density of H2 increased rapidly with a rise in pressure and temperature, whereas the density of the distilled water/brine declined marginally 1,2. The effects of pressure and temperature on the interfacial tension (IFT) of the H2/distilled water and H2/formation brine systems are presented in Table 2. The IFT of the H2/distilled water systems increased with temperature, however, the IFT of the H2/formation brine decreased with temperature. For example, the IFT between H2 and distilled water at 10 bar and 20 °C was 60.6 mN/m, whereas this value at 80 °C and 10 bar was 71.0 mN/m. Similarly, the IFT between H2 and formation brine at 10 bar and 20 °C was 63.6 mN/m, whereas this value at 10 bar and 80 °C was 58.5 mN/m. However, pressure had little effect on H2/distilled water and H2/formation brine IFT; this is attributed to the H2 density which changes only very little with pressure For instance, the IFT between H2 and distilled water at 80 °C and 10 bar was 71.0 mN/m, whereas this value at 100 bar and 80 °C was 68.4 mN/M. Similarly, the IFT between H2 and formation brine at 80 °C and 10 bar was 58.5 mN/m, whereas this value at 100 bar and 80 °C was 57.2 mN/M. At reservoir conditions, the behavior of IFT in the presence of H2 was similar to those of other gases (such as CO2, N2, C2H6, and C3H8) 3,4.
