Solid-State Hydrogen Storage Materials and Chemical Hydrogen Carriers
This community develops materials and chemical systems for the reversible storage, release, and generation of hydrogen, primarily to support fuel cell applications and broader energy storage needs.
The research focuses heavily on metal hydrides, with magnesium hydride and magnesium-nickel alloys being central subjects. A significant portion of the work involves chemical hydrogen carriers, specifically ammonia borane and sodium borohydride, often studied through hydrolysis reactions. The community also investigates hydrogen adsorption and absorption mechanisms, frequently employing density functional theory to model these interactions. Catalysts are a recurring theme, used to enhance the kinetics and efficiency of hydrogen release from these solid-state and chemical systems.
The largest share of the community's output is found in hydrogen research, accounting for 3.8% of all tracked hydrogen papers, with 19,994 papers in this group. Magnesium research also features prominently, representing 1.4% of magnesium studies with 2,074 papers.
There are 26,730 papers in this community, published most frequently in the International Journal of Hydrogen Energy, Journal of Alloys and Compounds, and The Journal of Physical Chemistry C.
Recent work continues to focus on magnesium-based systems, exploring nanosizing and spatially programmed confinement to improve storage performance. Other recent studies apply AI-driven discovery and first-principles analysis to evaluate new hydride structures, including perovskite and double perovskite materials, for their hydrogen storage capacity and stability.
