Natural gas can be collected from hydrate deposits by exchange with CO2, but the ensuing mixed hydrates and the path to a complete exchange are not fully understood. Here, computational analyses of neutron pair distribution functions of CH4, CO2 and mixed CH4-CO2 hydrates at 10 K reveal that the behavior of mixed gas species cannot be interpolated from properties of pure compounds.
