Abstract
A simple thermodynamical model taking into account non-ideality and inhomogeneity of
absorbed hydrogen molecular gas has been proposed to calculate hydrogen storage capacity
in carbon nanostructures as a function of temperature and pressure. The model
utilizing the effective interaction potential of the hydrogen molecule with the atoms of the
considered material, is based on the experimental equation of state and a local density
approximation for molecular hydrogen. We have applied the model for the search of the
optimal geometry for hydrogen storage of such promising carbon materials as a set of
graphene layers and bundles of carbon nanotubes. We demonstrate that the hydrogen
storage capacity depends on the geometry of material and discuss the origin of this effect
