Summary: Understanding the relationship between the structure, composition, and hydrogenation properties of intermetallic hydrides is crucial for improving their hydrogen storage performance. The ability to form hydrides and control their interaction with hydrogen is determined by their chemical composition. This study investigated a ScNiSn-based intermetallic hydride using various experimental techniques, including synchrotron and neutron powder diffraction, Mössbauer spectroscopy, hydrogenation, and thermal desorption spectroscopy. Computational calculations were also performed. The study revealed the mechanism of phase-structural transformation and the formation of unique metal-hydrogen bonding in the intermetallic alloy. At high pressures, a TiNiSi-type hydride was formed. The study also showed that scandium behaves similarly to the heavy rare earth metal holmium.

Summary: Since the initial assessment four decades ago, research on the hydrogen-storage applications of zirconium diberyllide, ZrBe2, has mainly focused on its hydride composition, ZrBe2H1.5. However, recent studies using neutron techniques have revealed the existence of two other ordered phases of ZrBe2Hx with lower hydrogen contents (x < 1.5) at low temperatures. These phases have different structural symmetries, H-sublattice orderings, and undergo higher-temperature phase transitions. This study provides a more complete understanding of the ZrBe2Hx phase diagram.

Summary: This paper investigates the electrochemical performance of Hf-modified Ti-Zr based AB2 Laves type metal hydride battery anode alloys. The alloys were characterized by X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM), and the electrochemical performance was studied through PCT diagrams and electrochemical tests. The Hf content in the alloys affected the phase composition, electrochemical discharge capacities, exchange current densities, H diffusion rates, and hydrogen storage capacity. The presence of Hf resulted in a decrease in discharge capacities and exchange current densities, while the alloy with the lowest Hf content showed the highest H storage capacity. The modification of the intrinsic properties of the alloys with Hf substitution played a role in the observed effects.

Summary: Thermal batteries using metal hydride pairs are attracting attention for their potential in thermochemical energy storage. The combination of high-temperature metal hydrides, such as Mg-based hydrides, and low-temperature metal hydrides, like AB2 type hydrides, offers high energy storage density and moderate energy storage efficiency. Improving the heat discharging performance of thermal batteries can significantly enhance the energy storage efficiency. In this study, the heat releasing performance of an MgH2/(TiZr)(MnFeCr)2-based thermal battery was experimentally investigated, with a focus on the effects of different LTMH bed heat transfer conditions. The results showed that active heat transfer conditions, such as forced convection or resistive heating, led to a thermochemical energy storage density ranging from 1500 to 1820 kJ/kg-Mg and a relatively high-temperature lift between 47 and 55 degrees Celsius. Additionally, the thermal battery discharged heat at a relatively high specific power, which could be advantageous for heat-to-work conversion applications using organic or steam Rankine cycles.
