“…The first synthesis of AB was reported in 1955, and several improved methods have been reported since then [40], [41], [42], [43], [44], [45], [46], [47], [48]. Besides hydrolysis, pyrolysis and alcoholysis can also dehydrogenate AB, however, hydrolysis has the advantages of a lower reaction temperature than pyrolysis and a faster hydrogen release rate than alcoholysis [49], [50], [51], [52], [53], [54], [55], [56], [57], [58].…”

Hydrogen is one of the clean energies that will play an important role in energy selection for the coming low-carbon society. Ammonia borane (NH3BH3, abbreviated hereafter as AB) is considered as a promising hydrogen storage material due to its high hydrogen content (19.6 wt%), stability under ambient conditions (white powder), and favorable properties in dehydrogenation. AB can release hydrogen via pyrolysis, alcoholysis, hydrolysis, etc. Among these, AB hydrolysis is a safe and effective route, as it proceeds under mild conditions in the presence of an appropriate catalyst without the need for additional heat sources. For practical application, it is important to develop an efficient catalyst that further improves the hydrolytic dehydrogenation properties of AB. Many papers and reviews have been published, suggesting the research is at an advanced stage. On the other hand, since new technologies are often patented before they are put into practical use, the status of patent publication is of significant interest. This mini-review analyzes patent applications published up to 2023 on hydrogen generation via catalytic AB hydrolysis. The patent search yielded 99 patent publications, which were examined not only by country and research institution but also by two representative types of catalysts derived from noble metal (abbreviated hereafter as NM) and non-NM. Based on the analysis, future research and development was discussed.

This paper has experimentally proved that hydrogen accumulates in large quantities in metal-ceramic and pocket electrodes of alkaline batteries during their operation. Hydrogen accumulates in the electrodes in an atomic form. After the release of hydrogen from the electrodes, a powerful exothermic reaction of atomic hydrogen recombination with a large energy release occurs. This exothermic reaction is the cause of thermal runaway in alkaline batteries. For the KSL-15 battery, the gravimetric capacity of sintered nickel matrix of the oxide-nickel electrode, as hydrogen storage, is 20.2 wt%, and cadmium electrode is 11.5 wt%. The stored energy density in the metal-ceramic matrix of the oxide-nickel electrode of the battery KSL-15 is 44 kJ/g, and in the cadmium electrode it is 25 kJ/g. The similar values for the KPL-14 battery are as follows. The gravimetric capacity of the active substance of the pocket oxide-nickel electrode, as a hydrogen storage, is 22 wt%, and the cadmium electrode is 16.9 wt%. The density of the stored energy in the active substance oxide-nickel electrode is 48 kJ/g, and in the active substance of the cadmium electrode it is 36.8 kJ/g. The obtained results of the accumulation of hydrogen energy in the electrodes by the electrochemical method are three times higher than any previously obtained results using the traditional thermochemical method.

The rapidly growing global need for environmentally friendly energy solutions has inspired extensive research and development efforts aimed at harnessing the potential of hydrogen energy. Hydrogen, with its diverse applications and relatively straightforward acquisition, is viewed as a promising energy carrier capable of tackling pressing issues, such as carbon emissions reduction and energy storage. This study conducts a preliminary investigation into effective hydrogen generation and storage systems, encompassing methods like water electrolysis, biomass reforming, and solar‐driven processes. Specifically, the study focuses on assessing the potential of nanostructured catalysts and innovative materials to enhance the productivity and versatility of hydrogen energy systems. Additionally, the utilization of novel materials not only improves hydrogen storage capacity and safety but also opens up possibilities for inventive applications, including on‐demand release and efficient transportation. Furthermore, critical factors such as catalyst design, material engineering, system integration, and technoeconomic viability are examined to identify challenges and chart paths for future advancements. The research emphasizes the importance of fostering interdisciplinary collaborations to advance hydrogen energy technologies and contribute to a sustainable energy future.
