Hydrogen Production, Storage, and Fuel Cell Energy Systems
This community researches the technologies required to produce, store, and utilize hydrogen as an energy carrier, with a specific focus on generating "green" hydrogen from renewable sources and integrating it into power grids and transportation networks.
The work centers on water electrolysis methods, including alkaline and solid oxide exchange membrane processes, to split water into hydrogen and oxygen. A significant portion of the research addresses the physical and chemical challenges of hydrogen storage, particularly through metal hydrides and liquid hydrogen systems, to enable safe and efficient transport. The community also investigates fuel cell technologies, such as proton exchange membrane and solid oxide fuel cells, which convert stored hydrogen back into electricity. These components are frequently studied in integrated energy systems, where hydrogen production, storage, and consumption are optimized together to reduce carbon emissions and enhance the reliability of renewable power supplies.
The largest share of the community's output is found in hydrogen research, accounting for 5.8% of all tracked hydrogen papers, which also represents the highest paper count within this group at 33,757. Carbon research follows with 7,782 papers, representing 0.9% of that element's total research.
The community comprises 44,248 papers, publishing most frequently in the International Journal of Hydrogen Energy, Journal of Alloys and Compounds, and Energy.
Recent work continues to focus on optimizing multi-energy systems that combine heterogeneous electrolyzers and fuel cells, as well as developing new materials like magnesium-based alloys and borophene for enhanced hydrogen storage and catalytic activity.
