“…It was also found that active cooling has a better filling rate than the natural convection. Moreover, Mellouli et al On the other hand, Patil and Gopal [19] studied the entropy generation and its relation to heating and cooling requirements of a metal hydride hydrogen storage system. In this study, a transient two dimensional energy equation along with suitable reaction kinetics and entropy balance equation was solved numerically.…”

For safety and operability concerns, the use of metal hydrides to store hydrogen appears to be particularly promising option for alternative energy at present. However, the process of adding, removing and distributing heat during the hydrogen charging/ discharging process is problematic due to the poor effective thermal conductivity of the metal hydride porous bed and the high enthalpies of H 2 adsorption/desorption. Therefore, heat transfer is a critical factor affecting the performance of metal hydride hydrogen (MHR) storage tanks. Over decade, many researches focused on MHR's operating conditions and its thermal management to improve its performance.

“…In 2012 Jinmoo's first 3D numerical simulation experiments verified heat and mass transfer phenomena of hydrogen storage reaction process and confirmed the capability to reduce the burden of cooling by lifting the hydrogen inlet pressure [15]. In 2013 Sharad numerically analyzed entropy increase of several phenomena under state of hydrogen storage, but irreversibility of the tank heat conduction temperature difference was still main factor [16].…”

“…Hydrogen stored as a absorbed element inside metal hydride materials offers certain advantages compared to high-pressure gaseous or cryogenic liquid storage systems in terms of compactness, storage at conditions close to ambient, energy required to store the hydrogen, possibility of tailoring metal hydrides to suit different temperature-pressure requirements, as well as being inherently safe because hydrogen is stored at low pressure [6][7][8]. The disadvantage is that it offers low energetic density per unit of mass due to the weight of the metal itself.…”

A two-dimensional axisymmetric model is developed to study the hydrogen desorption reaction and its subsequent discharge in a metal hydride canister. Experimental tests are performed on an in-house fabricated setup. An extensive study on the effects of the metal properties and boundary conditions on discharging performance is carried out through nondestructive testing (NDT). Results show that the desorption process is more effective if the activation energy for desorption (Ed) and the reaction enthalpy (∆H) decrease, and when the desorption rate coefficient (Cd) and the external convection heat transfer coefficient when the bottle is being heated (h) increase. Furthermore, porosity (ε) can be useful for the design of hydrogen storage systems, with a trade-off between charge/discharge time and storage capacity. Numerical and experimental results are compared achieving a good agreement. These results can be used to select metal hydride materials and also for the future evaluation of metal hydride degradation.
