Abstract: Energy storage is an increasingly important area of research both for use in alternative transportation and to enable the widespread use of intermittent energy sources such as wind and solar energy. This paper presents a multiphysics model of a novel technology for hydrogen storage, in which hydrogen is stored in a packed bed of metal hydride and released by application of steam through a number of competing reactions. The only suitable way to analyze reactor performance is with a multiphysics tool such as COMSOL. The model incorporates multiphysics couplings between reaction kinetics, flow in porous media, and heat transfer in and between porous media and gas. The model is used to study important performance metrics such as reaction front size, temperature, and propagation characteristics.
