“…The hydriding reaction, r 4 (Na 3 AlH 6 to NaAlH 4 ) has a higher activation energy than the reaction, r 2 , NaH to Na 3 AlH 6 . The P e for 2 mol.% Ti(OBu n ) 4 catalyzed materials is 5.4 MPa [9]. This could be due to catalyst placement preferentially at positions favorable to r 4 reaction.…”

“…Thermal transport architectures such as cooling tubes and metal foam structures need to be designed to meet the optimum operational characteristics of the hydrogen storage media. In this study, a solid/gas chemical kinetics model originally developed by El-Osery [6][7][8][9] to design conventional metal hydride systems was utilized. Many current models, such as the well-known Arrhenius model, are insufficient to characterize materials behavior under transient or partially discharged conditions.…”

Sodium alanate has been studied as a promising candidate material for reversible hydrogen storage due to its intermediate temperature range and relatively high storage capacity. Its rates of desorption and absorption of hydrogen have been shown to be enhanced by the addition of Ti in various compounds. To date, the sorption kinetics, especially absorption kinetics, is not well understood. In this study, a practical sorption kinetics model for TiCl 3 catalyzed NaAlH 4 has been developed to assist in the engineering design and evaluation of a prototype hydrogen storage system.

“…Particularly, when investigating heat and mass transfer in porous media e.g. in packed bed reactors used for energy storage [9] or fuel cells modeling [15]. Although, Marty et al [4] began a numerical work aiming to the prediction of the coupled heat and mass transfer characteristics of an industrial cylindrical tank during hydrogen storage, using the commercial CFD code FLUENT.…”

“…The coupled heat and mass transfer characteristics of hydride bed had been studied during the absorption and desorption of hydrogen in many investigations, using various mathematical models; one-dimensional model focused on heat conduction was earlier investigated [6], after considering convection in addition to conduction [7] then, by coupling the conduction and convection with thermal radiation effects [8,9]. It must be stressed that other higher dimensional and/or irregular geometries had been studied notoriously; the two-dimensional models [8,10,11] and the illustrious three-dimensional study of Aldas et al [3].…”
