Solid-State Hydrogen Storage Materials and Chemical Hydrogen Carriers
This community develops materials and chemical systems for the reversible storage, release, and transport of hydrogen, primarily for use in fuel cells and stationary energy applications.
The research focuses heavily on metal hydrides, with magnesium hydride and storage alloys forming the core of the materials landscape. A significant portion of the work addresses chemical hydrogen carriers, specifically ammonia borane and sodium borohydride, often involving hydrolysis reactions to generate hydrogen. Methodologies include density functional theory calculations to predict storage capacity and stability, alongside experimental synthesis of nanoparticles and nanostructured materials to enhance kinetics. Applications span fuel cell integration, efficient hydrogen generation, and solid-state storage solutions, with recurring emphasis on improving sorption properties and catalytic activity.
The largest share of the community's output is found in hydrogen research, accounting for 9.1% of all tracked hydrogen studies and comprising 10,305 papers within this group. Magnesium research contributes 1.7% of its total output, while nitrogen research accounts for 0.8%.
The community comprises 19,332 papers, publishing most frequently in the International Journal of Hydrogen Energy, Journal of Alloys and Compounds, and Journal of Power Sources. Recent work continues to explore magnesium-based storage systems, high-entropy alloys, and computational screening of new hydride structures, with a focus on enhancing storage performance through nanostructuring and catalytic support.
