Modeling and simulation of hydrogenation process of NaAlH4

Metal hydride systems offer a technological avenue for high-energy hydrogen-density storage devices for a range of transit and mobile applications. Because of its high-coupling thermal transfer, mass transfer, and chemical kinetics, metal hydride systems offer many possibilities. The purpose of this paper is to model and simulate quick refuelling of a 9 kg storage tank filled with sodium alanate. The hydride bed within the canister had a material density of 0.62 g ml of NaAlH4. Before each run, the canister is pressurized and heated. A simulation technique is designed and validated by what has been done to achieve and noted as the optimum design for the storage canister in literature. The use of the simulation tool for various storage concepts and geometries results in the final design. In this end, we have confirmed Ansys as an effective simulation tool to model hydrogen storage (absorption) to precisely forecast the replenishment of hydrogen and release processes for storage systems based on hydride of metals
