“…103 Since then, different schools have introduced various studies focused on the design and manufacture of hydrogen reactors based on the MgH 2 -system. [104][105][106] Based on the 8 th Strategic Plan of KISR (2015-2020) for NAM/ EBRC which concerns employing as-prepared Mgnanocomposite powders for PEM-FC applications, we succeeded in implementing MgH 2 /10 wt% (8 Nb 2 O 5 /2 Ni) nanocomposite buttons in the charging of a cell-phone battery, using a homemade integrated Ti-tank/PEM-FFC system.

“…The temperature of the desorption process was assumed to be 100 K above the respective equilibrium temperature (refer to Eqn (2)) because the desorption of metal hydride systems is in practice performed at temperatures remarkably higher than the respective equilibrium temperature because of kinetic issues. In the base case, this results in a temperature of 325°C, which is in the range of practical [30][31][32]37]. In the sensitivity analysis performed, the desorption temperature and pressure are varied in a wide range to cover a variety of possible operation conditions and to show the influence of these conditions.…”

“…Assuming a desorption temperature of 350 °C and a common insulation of the container, it can be shown that for desorption times shorter than 6 h, the additional heat demand is below 5 % of the original heat demand and therefore negligible. In practice, high‐temperature metal hydride systems exhibit even shorter desorption times (1 to 3.5 h ). For this reason, heat loss effects were not considered in this study.…”

Summary Metal hydrides are considered as promising candidates for hydrogen storage as they exhibit higher energy densities than compressed gas storage storages. This study represents a theoretical thermodynamic analysis of metal hydride‐based hydrogen storage systems, focusing mainly on the energy demand to operate the storage system and the resulting efficiency. The main energy demand occurs during hydrogen release. This energy demand is composed of three contributions: the heat required to heat the hydride up to desorption temperature, the heat of reaction and the work of compression to reach the targeted outlet pressure. A sensitivity analysis was performed to demonstrate the impact of several parameters, for example, heat of reaction and hydrogen uptake on the energy balance. The most influential parameter is the heat of reaction. The hydrogen uptake does not have a noticeable influence as long as it is not too low. Several possibilities to improve the efficiency of the storage system are discussed (heat integration and the application of a heat storage system). Heat integration can significantly improve the overall efficiency, whereas the application of a heat storage system does not seem realistic. Compared with other hydrogen storage technologies, metal hydrides can feature higher efficiencies than low‐temperature hydrogen storage concepts, for example, liquefied or cryo‐adsorbed hydrogen. The efficiencies of a metal hydride storage system are similar to those reached with a system based on liquid organic hydrogen carriers. Copyright © 2016 John Wiley & Sons, Ltd.

“…Complex hydrides operate over a broad range of temperatures. Since the hydrogenation and dehydrogenation reactions are endothermic and exothermic [142], it is unlikely that the heat generated or required by the chemical reactions can be kept in a closed loop or recycled. The safety of hydrides is also questionable.…”

Hydrogen Storage for Mobility: A Review

2019

View full text Add to dashboard Cite

Numerous reviews on hydrogen storage have previously been published. However, most of these reviews deal either exclusively with storage materials or the global hydrogen economy. This paper presents a review of hydrogen storage systems that are relevant for mobility applications. The ideal storage medium should allow high volumetric and gravimetric energy densities, quick uptake and release of fuel, operation at room temperatures and atmospheric pressure, safe use, and balanced cost-effectiveness. All current hydrogen storage technologies have significant drawbacks, including complex thermal management systems, boil-off, poor efficiency, expensive catalysts, stability issues, slow response rates, high operating pressures, low energy densities, and risks of violent and uncontrolled spontaneous reactions. While not perfect, the current leading industry standard of compressed hydrogen offers a functional solution and demonstrates a storage option for mobility compared to other technologies.
