Abstract

This paper presents the results of an exptl. study of supercrit. H2 adsorption in nanoporous carbon plus some supporting data from mol. simulations of adsorption. This is part of a broad examn. of the potential of these materials as storage media for H2 in sustainable energy systems, in comparison with other proposed storage media such as C nanofibres and metal hydrides, and with other storage systems such cryogenic liq. and high-pressure gas. Note that the new term nanoporous refers to pores in the size range 0.1 to 100 nm, as proposed in another Mays paper in these Proceedings. Recent results of this work appear to show high H2 uptakes in nanoporous carbon, but that these uptakes only occur for very pure H. The authors propose a pore blocking mechanism to account for this. While at present high uptakes only appear possible at liq. N temps., the pressures are reasonable (
