“…Metal hydride bed (MHB) has been justified to be one of the most promising technologies because of its safe storage and efficient delivery of hydrogen . However, hydrogen absorption and desorption behaviors associated with MHB are always accompanied by substantial heat and mass exchanges, and in turn, the reactor performance is dominated by several critical factors, such as material properties, structural arrangements, and cooling systems . A comprehensive understanding of the heat transfer behavior coupled with multiphysics is therefore of critical important to conduct an integrative assessment of reactor structure performance.…”

Summary Nowadays, metal hydrides are generally deemed as one of the most potential materials that are in favor of compact hydrogen storage for industrial applications. This work was committed to evaluate the thermal performance of a circular‐shaped‐tube thin double‐layered hydrogen storage reactor using a three‐dimensional model. Finite element simulations were conducted to systematically study the influences of structural geometries, cooling patterns, and material thermophysical properties on the heat diffusion behavior under the framework of convection heat transfer. The results indicate that the proposed model effectively characterizes temperature evolutions during hydrogen absorption process. Moreover, a statistical analysis was performed to reveal the sensitivity sequence of these factors on the total thermal performance, suggesting that decreasing the hydride layer thickness, increasing the number of U‐shaped cooling tubes, accelerating the cooling fluid flow rate, and enhancing the thermal conductivity are more beneficial to the thermal performance improvement. Detailed analysis confirms the possibility of developing the present hydrogen storage tank utilizing metal hydrides for engineering practice.

“…building the model with the manifold individual parameters affecting the speed of hydrogen release in building brick-like fashion. [10][11][12][13][14][15][16][17][18][19] While this appears to be an obvious path towards a solution for an issue of the kind, it requires for metal hydride fuel cell energy systems full knowledge of a multitude of properties which are often not readily at hand and the dynamic nature of metal hydride bed properties makes the matter even more complex. Hence the bottom-up approach is resource-intensive; a further shortcoming is that its results are case-specific which benefits neither the accommodation of fundamental adjustments nor the comparability of distinctively different design options.…”

A simple and practical method for describing transient metal hydride tank behaviour in fuel cell energy systems is outlined, requiring only a minimum of fundamental thermodynamic and kinetic input data. The solution is developed top-down by means of the generic pressure-time course of hydrogen release from a metal hydride tank that is coupled to a fuel cell.This approach towards a comprehensive model allows for the untangling of engineering and chemistry issues and offers an alternative to the transient simulation of metal hydride bed temperature distribution. While a practitioner of the art may benefit from that result in its own right, the essence of this work rests with the paradigm of understanding the problem.

“…It is believed that ultimately solid‐state hydrogen‐storage materials are promising alternatives due to the low working pressure and manipulatable temperature and pressure parameters. Candidates for these material include metal hydrides (Mg−H, Pd−H, V−H), alloys (LaNi 5 H 6 , TiFeH 2 , Mg 2 NiH 4 , Ti−V−Mn−H), some complex hydrides and chemical hydrides (NaAlH 4 , LiBH 4 , LiNH 2 ), and physisorption adsorbents (carbon‐based or metal–organic framework porous structures) . These materials have a wide range of performance parameters, for instance, working temperature, sorption kinetics, activation condition, cycling ability, and equilibrium hydrogen pressure.…”

For the realization of a hydrogen economy, one enabling technology is hydrogen storage. Magnesium‐based materials (MBMs) are very promising candidates for hydrogen storage due to the large hydrogen capacity and low cost. Challenges in the development of magnesium‐based hydrogen‐storage materials for various applications, particularly for onboard storage, are poor kinetics and unsuitable thermodynamics. Herein, new methods and techniques adopted by the researchers in this field are reviewed, with a focus on how different techniques could affect the hydrogen‐storage properties of MBMs, including kinetics and thermodynamics. Based on current progress, research trends in MBMs for various applications are introduced. Classical work from some pioneers, important milestones, and the latest development for these possible applications are summarized and future prospects in these fields are discussed.
