Chemical Looping and Solar Thermochemical Cycles for Hydrogen and Syngas Production
This community develops solid oxide oxygen carriers and reactor systems to produce hydrogen, syngas, and liquid fuels from methane, biomass, and water using chemical looping and solar thermochemical processes.
The work centers on iron, copper, and cerium-based oxide carriers that shuttle oxygen between fuel and air in fluidized bed or fixed-bed reactors. Key applications include chemical looping combustion for carbon capture, steam methane reforming for hydrogen, and solar-driven water and carbon dioxide splitting. Recent efforts focus on perovskite materials, lattice oxygen mobility, and integration with Brayton and Stirling cycles to improve thermal efficiency and reduce emissions.
The community is most prominent in hydrogen research, representing 40.0% of that element's tracked papers, and in oxygen research, where it accounts for 40.0% of the total. It also constitutes 20.0% of sulfur research and 8.0% of cerium research.
The community comprises 7,172 papers, primarily published in the International Journal of Hydrogen Energy, Fuel, and Chemical Engineering Journal.
Recent work includes techno-economic assessments of biomass-to-liquid fuel production via chemical looping, the development of CeO2-modified red mud oxygen carriers for hydrogen production, and the design of monolithic SiC catalysts for sulfur-based thermochemical hydrogen production.
