Abstract:Adsorbed hydrogen is being considered as a potential energy carrier for vehicular applications to replace compressed gas due to its high energy density capability. A new design of hydrogen storage vessel using novel carbon sorbents and heat pipes thermal control is the subject of research program oriented on 5–10 kg of hydrogen be stored on-board. Porous structure and hydrogen-sorption capacities of activated carbon materials are considered. Numerical analysis based on 2D nonequilibrium model of heat and mass transfer in the sorbent cylinder is carried out with the aim to investigate and optimize the sorption storage system. Obtained numerical and experimental data testify the possibilities of a new sorbent bed to reduce the operating pressure and increase a gas storage capacity.
