“…In , the authors simulate the coupling of a solid oxide fuel cell with a high‐temperature metal hydride and concluded that a thermal integration of both systems is possible. The realization of this concept is considered as ‘viable but not easy’ . By these couplings and assumed fuel cell efficiencies of 50 %, overall electric‐to‐electric efficiencies of 29 % are possible for the metal hydride‐based electricity storage system.…”

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.

“…Consequently, using complex hydride systems such as NaAlH 4 [277][278][279][280][281][282] and Mg(NH 2 ) 2 + 2LiH [283] in conjunction with HT-PEMFCs is now being investigated. The integration of SOFCs with MgH 2 [284][285][286][287][288], a metal hydride that historically suffered from high thermodynamic stability and poor kinetics, highlights the potential of CMHs for this application.…”

Hydrogen has a very diverse chemistry and reacts with most other elements to form compounds, which have fascinating structures, compositions and properties. Complex metal hydrides are a rapidly expanding class of materials, approaching multi-functionality, in particular within the energy storage field. This review illustrates that complex metal hydrides may store hydrogen in the solid state, act as novel battery materials, both as electrolytes and electrode materials, or store solar heat in a more efficient manner as compared to traditional heat storage materials. Furthermore, it is highlighted how complex metal hydrides may act in an integrated setup with a fuel cell. This review focuses on the unique properties of light element complex metal hydrides mainly based on boron, nitrogen and aluminum, e.g., metal borohydrides and metal alanates. Our hope is that this review can provide new inspiration to solve the great challenge of our time: efficient conversion and large-scale storage of renewable energy.

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.
