Summary: The synthesis, thermodynamic destabilisation, and hydrogen sorption properties of the M0.2Ca0.8MgH4 hydride system (where M = Na or Li) were investigated in this study. Substitution of Li and Na into Ca-Mg-H ternary hydride caused diffraction peaks to shift to higher angles, and different endothermic reactions were observed.

Summary: In this study, Mg85Ni14Ce1 amorphous alloy films with different thicknesses were prepared, and the nanosize effect on hydrogen desorption and cycling properties was investigated. It was found that as the size decreases, the hydrogen storage kinetics of the alloy greatly increase, and the nanosized amorphous alloys can reversibly absorb and desorb hydrogen at a low temperature. Moreover, the alloy structure can be fully recovered after hydrogen absorption and desorption cycles. Therefore, nanosized amorphous alloys are promising candidates for reversible hydrogen storage applications.

Summary: In this study, the hydrogen sorption behavior of Mg-5%La alloy after the first absorption was investigated using in-situ synchrotron Powder X-ray Diffraction (PXRD) and in-situ High Voltage Transmission Electron Microscopy (HVTEM). Two distinct phase evolutions were identified during the desorption process: continuous transformation of LaH3 into LaH2+1/2 H2 starting from 250 degrees C, and decomposition of MgH2 into Mg+H2 between 440 and 460 degrees C. It was determined that the alloy is cyclable in the subsequent absorption/desorption cycling after the first hydrogen absorption, without the involvement of Mg12La intermetallic.

Summary: It was unexpectedly found that the desorption behavior of magnesium rich Mg-Ni hydrides improved after exposure to air for a certain period. After 4 months of exposure, the dehydrogenation peak and onset temperature were lowered by 150°C and 130°C, respectively. Furthermore, the air-exposed sample exhibited rapid hydrogen absorption and desorption rates at 300°C. The improvement in reactivity is attributed to the refining of the powders, the in-situ formed magnesium hydroxide layer, and the presence of Ni as active catalytic sites.

Summary: The present studies investigate the catalytic effect of carbon nanostructures (Graphene and single-wall carbon nanotubes, as well as their composites) on the hydrogen sorption behavior of 1:2 Mg(NH2)(2)-LiH/Li4BH4(NH2)(3). It is found that adding 2 wt% single-wall carbon nanotubes to Mg(NH2)(2)-2LiH/Li4BH4(NH2)(3) results in superior hydrogen sorption compared to 2 wt% Graphene and (Graphene and single-wall carbon nanotubes) composites. The single-wall carbon nanotubes catalyzed sample exhibits lower onset desorption temperature, better de/re-hydrogenation kinetics, and good cyclic stability.

Summary: Multiple Ti and Li atom doped carbon nanorings were studied for hydrogen storage using density functional theory. The results showed that both Ti and Li doped carbon nanorings were thermodynamically stable and more stable than undoped carbon nanorings. Metal clustering, which reduces hydrogen storage capacity, was not observed in the doped nanorings. The Ti doped carbon nanoring was found to be suitable for hydrogen storage at low temperatures and high pressures, while the Li doped carbon nanoring was not suitable. The hydrogen desorption temperatures for the Ti and Li doped nanorings were 450 K and 113 K respectively, indicating stronger interaction between H2 molecules and Ti doped carbon nanoring.

Summary: Magnesium borohydride is a promising material for hydrogen storage, but its slow dehydrogenation kinetics and formation of intermediate polyboranes limit its application in clean energy technologies. This study presents a novel approach of modifying the physicochemical properties of magnesium borohydride by adding reactive molecules in the vapor phase. The effects of four different molecules on the additive-Mg(BH4)(2) interaction and hydrogen release at lower temperatures are examined. The results demonstrate the efficacy of this approach and provide a new path for additive-based modification of hydrogen storage materials.

Summary: Porosity and surface area analysis are important in modern materials science. However, there is a lack of attention to the reproducibility issue in calculating BET surface areas from identical isotherms, raising concerns over the reliability of reported BET areas. To address this, a new computational approach called BET surface identification (BETSI) has been developed for accurately and systematically determining the BET area of nanoporous materials.

Summary: We conducted a thorough study on the effect of adding 10% Al into the Ti0.33V0.33Nb0.33 alloy on the hydrogen storage properties. The results showed that while the storage capacity decreased by 20%, several other properties were enhanced by the presence of Al, such as lower hydrogen desorption temperature and improved stability during cycling. This study demonstrates that adding Al into multi-principal element alloys is a promising strategy for designing novel materials for hydrogen storage.

Summary: We are witnessing the dawn of hydrogen economy, where hydrogen is becoming a primary fuel for heating, transportation, and energy storage. Metal-organic frameworks (MOFs) have emerged as promising adsorbent materials for hydrogen storage, but their use has been limited by a lack of densification methods. In this study, researchers screened and analyzed a database of MOFs to find an optimal material for hydrogen storage, and successfully synthesized and evaluated a monolithic MOF with high storage performance at lower operating pressures.

Summary: Hydrogen, with the highest gravimetric energy density among energy carriers and water as its only oxidation product, is highly attractive for transportation and stationary power applications. However, its low volumetric energy density presents challenges in storage, leading to the development of chemical-based storage methods using various materials. Addressing these challenges requires a deeper understanding of the complex kinetics, mass transport, and microstructural phenomena associated with hydrogen uptake and release. Solutions will require interdisciplinary approaches involving catalysis, data science, nanoscience, interfacial phenomena, and dynamic or phase-change materials.

Summary: Metal boride nanostructures have great potential for hydrogen storage applications. However, their synthesis is challenging due to high surface energy, strong bonding, and difficult surface termination. Mechanochemical exfoliation of magnesium diboride in zirconia produces ultrathin MgB2 nanosheets with high yield. High-pressure hydrogenation and dehydrogenation of these nanosheets reveal a hydrogen capacity 50 times larger than bulk MgB2. The enhancement is attributed to defective sites created by ball-milling and incomplete Mg surface coverage. The exfoliation and creation of ultrathin layers offer a promising direction for high-capacity hydrogen storage.
