Database of thermophysical properties of H2/CO2/CO/CH4/H2O mixtures

As a potential alternative to fossil fuel, hydrogen has attracted much attention due to its renewable and environmentally friendly properties. Systems built for hydrogen-production and hydrogen-application tend to be larger, more integrated and more complex. In order to more efficiently design the vital components of hydrogen energy systems, accurate esti -mations of the thermodynamic and thermophysical properties of hydrogen-containing mixtures involved is essential. In this study, we introduced methods typically for calcu-lating the thermodynamic and thermophysical properties of H2/CO2/CO/CH4/H2O mixtures, and established the technical database covering a wide range of mole fractions, pressures and temperatures. Moreover, a user-friendly software integrating all the calculation methods called H2MixThermoDatabase is compiled, whose code has been made available on the GitHub page for other researchers to effectually facilitate the further developments of hydrogen energy system.(c) 2023 Hydrogen Energy Publications LLC.
