Abstract: Diffusion processes in $\mathrm{C}_0$ and $\text{sT}'$ structures of hydrogen gas hydrates were studied by the molecular dynamics method. The analysis of mean square displacements shows that hydrogen molecule diffusion in the hydrates on the nanosecond time scale has an anisotropic and anomalous character. The features of guest molecule diffusion are determined by a lattice geometry.
