Hydrogen Production, Storage, and Fuel Cell Systems
This community researches the technologies required to generate, store, and utilize hydrogen as a clean energy carrier, focusing on methods like water electrolysis and metal hydrides, as well as the fuel cells that convert it back into electricity.
The work centers on the full hydrogen value chain, with a heavy emphasis on storage solutions such as metal hydrides, ammonia borane, and liquid organic hydrogen carriers. Production methods are dominated by water electrolysis, including alkaline and proton exchange membrane technologies, alongside biohydrogen and green hydrogen generation from renewable sources. These components are frequently integrated into hybrid energy systems, where hydrogen fuel cells provide power, and the overall performance is evaluated through life cycle assessments and techno-economic analyses. The research often explores the integration of solar and wind energy with electrolysis to create sustainable, low-carbon energy systems.
The largest share of the community's output is found in hydrogen research, accounting for 17.6% of all hydrogen studies, which also represents the highest paper count within this group at 26,803 papers. Magnesium research follows with a 1.6% share, and nitrogen with a 1.3% share.
The community comprises 49,635 papers, published predominantly 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 integrate hydrogen storage and fuel cells, with specific attention to magnesium-based storage materials, borophene catalysts for hydrogen evolution, and the global assessment of hydrogen projects for greenhouse gas mitigation.
