Green Hydrogen Production, Storage, and Fuel Cell Systems
This community focuses on the technical and economic pathways for producing, storing, and utilizing hydrogen as a clean energy carrier, primarily through water electrolysis and fuel cell technologies.
The research centers on optimizing hydrogen production via water electrolysis, with significant attention to solid oxide and proton exchange membrane fuel cells. Key themes include large-scale hydrogen storage solutions, such as liquid hydrogen and underground reservoirs, and the integration of hydrogen into broader energy systems. The work frequently employs life cycle assessment to evaluate environmental impacts and explores hybrid systems that combine renewable energy sources like solar and wind with hydrogen infrastructure. Applications range from decarbonizing industrial processes and electric vehicles to managing power grids and reducing carbon dioxide emissions through carbon capture integration.
The largest share of the community's output is found in hydrogen research, accounting for 4.8% of all hydrogen-related papers, with 25,296 papers in this group. Carbon research follows with 12,391 papers, representing 1.5% of carbon-related studies.
The community comprises 51,431 papers, publishing most frequently in the International Journal of Hydrogen Energy, Fuel, and Energy.
Recent work continues to focus on optimizing hydrogen-oriented multi-energy systems and assessing the environmental impact of hydrogen infrastructure, including reviews of national strategies for scaling green hydrogen and the integration of heterogeneous electrolyzer and fuel cell technologies in industrial settings.
