%X To cope with the tight timeframe of the global transformation from fossil to renewable energy sources, efficient,methods and tools such as process and system simulation are essential for rapid development, cost-efficient design,and scale-up validation of new energy systems. This numerical analysis investigates the coupling of a stationary,metal hydride (MH) hydrogen storage system with a low-temperature 10 kW proton exchange membrane (PEM),electrolyzer as a fast-responding and well-controllable hydrogen source. The heat management of the solid-state,storage tank is improved through additional aluminium fins and an external cooling jacket. For modeling and process,simulation, Aspen Custom Modeler® is used to study the mass and heat transfer phenomena in the hydrogen storage,tank, as well as the interaction with the electrolyzer. The hydrogen tank is designed to store a total capacity of 700 g,of H2 using 62.5 kg commercial room temperature AB2-alloy, Hydralloy C5®. The operating pressure varies from 5 to,38 bar H2, while the coolant temperature varies from 20 to 60°C depending on the exothermic absorption or,endothermic desorption processes.
