Hydrogen (H2) is widely considered as an ideal CO2-free energy carrier. Physisorption in nanoporous carbons is a promising way for reversible H2 storage at pressure below 100 bar. The gravimetric amount of stored H2 strongly depends on the nanopore structure, notably the mean pore size being typically below one nanometer. Yet the mechanisms which determine the storage capacity are still not fully understood. Here we present in-situ small-angle neutron scattering data of H2 adsorption in nanoporous carbons at low pressures up to 1 bar, and discuss the influence of pore structure on the density distribution of the adsorbed H2.
