“…7 Not only does hydrogen have a high energy mass density (120 kJ•kg −1 ), but it also has ideal physical properties for long-distance transport, ease of use, and easy transmission through various methods of hydrogen storage, liquefaction, and compression. [1][2][3]8 More and more attention is being paid to the efficient storage of hydrogen. In the course of this research, solid hydrogen storage materials stand out.…”

“…A global crescendo of low-carbon development and sustainable economic development is on the horizon. The use of carbon-based resources such as fossils as fuel no longer meets the needs of today’s energy use and environmental development. − As a result, renewable energy has become a worldwide research hot spot. As an important renewable energy source, hydrogen is considered to be an ideal medium for the synergistic optimization of cross-energy networks. − It can play an important role in China and the world’s energy system.…”

While non-precious metals like Co and Ni have shown good performance in generating hydrogen from NaBH 4 , the challenges of catalyst agglomeration and deactivation have become a focus of future research. To address this issue, in this study, Co nanoparticles on graphene carriers and controllably replaced with nickel atoms to form highly dispersed two-dimensional (2D)/2D Ni−Co nanolayers by Galvanic Replacement Reaction were prepared. Characterization analyses (transmission electron microscope (TEM), scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS), and hydrogen temperatureprogrammed desorption (H 2 TPD)) suggested that 2D/2D Ni− Co nanolayer catalysts were observed with ultrathin nanolayer structures after using graphene as a carrier. In the hydrogen generation process, the Ni atoms as the main active centers, combined with the synergistic effect of Co and the good conductivity of graphene, contribute to improved hydrogen release. The 2D material showed good hydrogen generation performance, with a rate of 4300 mL•(min•g) −1 , maintenance of 94% hydrogen generating activity after five cycles, and lower activation energy of 29 kJ•mol −1 .

“…Thus, it is noted that green hydrogen produced from renewable energy sources (Thapa, Neupane, Yang & Lee, 2021), poses little or no threat to the environment and increasing its production will support decarbonization targets (Raman, Nair, Prakash, Patwardhan & Nedungadi, 2022). In other words, a green hydrogen production system consisting of water electrolysis and a renewable energy plant must be expanded to prepare for the future hydrogen society (Lee, Choe, Lee, Gu, Cho, Won & Lim, 2022).…”

Purpose: to investigate the behavior and tendency of the formation of social networks of the scientific production on the Green Hydrogen theme published in scientific journals indexed in EBSCO. Theoretical framework: the theme of green hydrogen has been gaining attention and strength in the current context of global energy transition, as it is a clean alternative for generating energy for electricity, industry, heating, and transport sectors, and, in replacing fuels to carbon base, influencing sustainable development. Method: bibliometric analysis techniques were used, and predominantly social network analysis (SAR) through one-mode and two-mode network analysis. Results and conclusion: evolution of the theme in academia; weak ties in co-authorship and institutional networks; relevance of China and its originating institutions in the scientific production of the subject investigated; the most central keywords were: hydrogen, green hydrogen, renewable energy, production and hydrogen production; and the most fruitful themes were: production, sustainability, energy and carbon emissions. It concludes with a macro and contemporary view of the theme of green hydrogen in the international literary academic field. Research implications: the present study contributed to a better understanding and understanding of the formation of collaboration networks of the actors involved in the process of building international scientific knowledge, and, by verifying that green hydrogen presents opportunities for economic growth and job creation, this research also contributes to creating an entrepreneurial and social research agenda. Originality/value: to investigate the international scientific production on the theme of green hydrogen, as this is an emerging theme in the global academic literature, and, therefore, to verify that the referred theme gains strength through researchers and their respective studies.

“…This particular arrangement allows to operate the engine independently from the wheels and then to exploit, for each road load condition, the best ICE efficiency operating condition [1,2]. As far as greenhouse gasses emission reductions are concerned, the most promising alternative to fossil fuels, as an energy carrier, is represented by the so-called green hydrogen, produced by water electrolysis with renewable energy sources [3,4]. A stoichiometric air-hydrogen mixture has a volumetric power density comparable with gaseous hydrocarbons, hydrogen can be stored and transported, and its combustion produces only water.…”

Hybrid electric vehicles are currently one of the most effective ways to increase the efficiency and reduce the pollutant emissions of internal combustion engines. Green hydrogen, produced with renewable energies, is an excellent alternative to fossil fuels in order to drastically reduce engine pollutant emissions. In this work, the author proposes the implementation of a hydrogen-fueled engine in a hybrid vehicle; the investigated hybrid powertrain is the power-split type in which the engine, two electric motor/generators and the drive shaft are coupled together by a planetary gear set; this arrangement allows the engine to operate independently from the wheels and, thus, to exploit the best efficiency operating points. A set of numeric simulations were performed in order to compare the gasoline-fueled engine with the hydrogen-fueled one in terms of the thermal efficiency and total energy consumed during a driving cycle. The simulation results show a mean engine efficiency increase of around 17% when fueled with hydrogen with respect to gasoline and an energy consumption reduction of around 15% in a driving cycle.
