To make these results applicable to real-world data, an equation of state (EOS) is required to convert the computed fugacity to pressure. The Van der Waals 29 (Equation ) and Peng-Robinson 30 (Equation ) equations of state (EOS) were both considered. In each equation, empirical terms a and b are used, with values of 0.2476 L 2 bar/mol 2 and 0.02661 L/mol, respectively, for hydrogen. Other variables include T for temperature, ν for molar volume, R for the gas constant, P for pressure, f for fugacity, and Z for compressibility factor. Note that for simplicity, terms A, B, and C are used which represent various groupings of the previously mentioned variables into single terms. Figure demonstrates the differences between an ideal gas (y=x), Van der Waals EOS (blue), and the Peng-Robinson EOS (orange). In the low pressure regime <100 bar, Hydrogen gas will act like an ideal gas. At the 700 pressure range however, it strays drastically from the ideal pressures. Between the two EOS, the calculated pressures showed a 0.735% difference between the two EOS. Though both seem to be fairly interchangeable under these conditions, we chose to use the Van der Waals EOS for fugacity and pressure conversions.
