Advanced sorbents for thermally regulated hydrogen vessel

Abstract Adsorbed hydrogen storage and transportation technology recently became competitive to compressed gas method due to high energy density capability achievements. New composite material (metal-hydride particles on the activated carbon fibre matrix) was developed as efficient hydrogen sorbent for gas storage and transportation system application. Effect of the carbon matrix nature and metal hydride content experimentally was investigated. To enhance the performance and thermodynamic efficiency of the gas storage vessel a heat pipe thermal control system was suggested. A two-dimensional transient model developed to analyze the influence of the thermal control on the operating characteristics of the sectional storage vessel with hydrogen and heat pipes.
