High hydrogen absorption and desorption rates are two significant index parameters for the applications of hydrogen storage tanks. The analysis of the hydrogen absorption and desorption behavior using the isothermal kinetic models is an efficient way to investigate the kinetic mechanism. Multitudinous kinetic models have been developed to describe ...

The kinetics of most chemical energy storage/conversion systems depend on the mass transport through matter, which is rate-limited by various kinetic barriers. The distinction of the barriers by static and dynamic interfaces helps in reducing their impact and therefore enhancing the overall kinetics. The concept is introduced along examples of stat...

We report here a thorough study on the effect of 10 at.% Al addition into the ternary equimolar Ti0.33V0.33Nb0.33 alloy on the hydrogen storage properties. Despite a decrease of the storage capacity by 20 %, several other properties are enhanced by the presence of Al. The hydride formation is destabilized in the quaternary alloy as compared to the ...

Catalyzing capping layers on metal hydrides are employed to enhance the hydrogenation kinetics of metal hydride-based systems such as hydrogen sensors. Here, we use a novel experimental method to study the hydrogenation kinetics of catalyzing capping layers composed of several alloys of Pd and Au as well as Pt, Ni, and Ru, all with and without an a...

Helium is insoluble in most metals and precipitates out to form nanoscale bubbles when the concentration is greater than 1 at.%, which can alter the material properties. Introducing controlled defects such as multilayer interfaces may offer some level of helium bubble management. This study investigates the effects of multilayered composites on hel...

Accurately characterising the hydrogen sorption properties of materials is critical to improving reproducibility in hydrogen storage material research. This review covers the main techniques used for this purpose, including important aspects of troubleshooting during the measurement process. It also proposes reporting guidelines for hydrogen sorpti...

The applicability of an alloy as a hydrogen storage media mostly relies on its pressurecomposition-temperature (PCT) diagram. Since the PCT diagram is compositiondependent, the vast compositional field of high entropy alloys, complex concentrated alloys or multicomponent alloys can be explored to design alloys with optimized properties for each app...

AbstractThe formation process of the well-known biomedical alloy of the Ti–21Nb–5Zr (at %) composition is studied by the hydride cycle (HC) method. TiH2 hydrides (content H2, 4.01 wt %), ZrH2 (content H2, 2 wt %), and NbH1.23 (content H2, 1.31 wt %) are preliminarily synthesized by self-propagating high-temperature synthesis (SHS). The experiments ...

A general problem when designing functional nanomaterials for energy storage is the lack of control over the stability and reactivity of metastable phases. Using the high-capacity hydrogen storage candidate LiAlH4 as an exemplar, we demonstrate an alternative approach to the thermodynamic stabilization of metastable metal hydrides by coordination t...

A sapphire single-crystal gas-pressure cell without external support allowing unobstructed optical access by neutrons has been developed and optimized for elastic in situ neutron powder diffraction using hydrogen (deuterium) gas at the high-intensity two-axis diffractometer D20 at the Institut Laue-Langevin (Grenoble, France). Given a proper orient...
