In-situ small-angle neutron scattering studies of H-2 confined in small pores of polyfurfuryl alcohol-derived activated carbon at room temperature have provided for the first time its phase behavior in equilibrium with external H-2 at pressures up to 200 bar. The data were used to evaluate the density of the adsorbed fluid, which appears to be a function of both pore size and pressure and is comparable to the density of liquid H-2 in narrow nanopores at similar to 200 bar. The surface molecule interactions responsible for densification of H-2 within the pores create internal pressures that exceed the external gas pressure by a factor of up to similar to 50, confirming the benefits of adsorptive storage over compressive storage. These results can be used to guide the development of new carbon adsorbents tailored for maximum H-2 storage capacities at near-ambient temperatures.
