    The binary mixtures of water and selected pure gases, e.g., carbon dioxide and methane, relevant in CCS technologies, has been investigated in detail. The gas hydrate model of Ballard and Sloan [Fluid Phase Equilib. 194, S. 371–383, 2002] was adapted and modified to accurately predict the properties of selected pure sI hydrate formers. The modified model was fitted to thermal expansion, isothermal compressibility and three-phase hydrate formation data. The compressibility of sI hydrates was analyzed with the help of Murnaghan and Birch-Murnaghan equations. The novelty of this model is that it allows for the prediction of hydrate formation in combination with the most accurate equations available for the fluid and pure solid phases. Consequently, the thermodynamic properties together with hydrate formation conditions in the system H2O + CO2 can be calculated with good accuracy over wide temperature and pressure ranges [Fluid Phase Equilib. 338, S. 100–113, 2013].
