Progress on computer-aided and experimental determination of thermophysical properties of gas mixtures containing hydrogen

In the project H2MIXPROP, highly accurate data for several thermophysical properties of gaseous mixtures containing molecular hydrogen are obtained by state-of-the-art theoretical approaches and experimental methods. Such data are required for many technical applications in the transition of the energy supply system to renewable energy sources, in which hydrogen is expected to play a prominent role. This contribution describes theoretical results for cross second virial coefficients of several binary mixtures, the development and validation of a path integral Monte Carlo code for the simulation of quantum gases, and the current status of the experimental tasks.
