High-flux solar-driven thermochemical dissociation of CO2 and H2O using nonstoichiometric ceria
William C. Chueh,Christoph Falter,Mandy Abbott,Danien Scipio,Philipp Furler,Sossina M. Haile,Aldo Steinfeld,Aldo Steinfeld +7 more
TL;DR: By using a solar cavity-receiver reactor, the oxygen uptake and release capacity of cerium oxide and facile catalysis at elevated temperatures to thermochemically dissociate CO2 and H2O, yielding CO andH2, respectively were combined and stable and rapid generation of fuel was demonstrated over 500 cycles.
Journal ArticleDOI
Solar thermochemical production of hydrogen--a review
Aldo Steinfeld,Aldo Steinfeld +1 more
TL;DR: In this paper, the authors review the underlying science and describes the technological advances in the field of solar thermochemical production of hydrogen that uses concentrated solar radiation as the energy source of high-temperature process heat.
Journal ArticleDOI
Solar hydrogen production via a two-step water-splitting thermochemical cycle based on Zn/ZnO redox reactions
Aldo Steinfeld,Aldo Steinfeld +1 more
TL;DR: In this article, a 2nd-law analysis performed on the closed cyclic process indicates a maximum exergy conversion efficiency of 29% (ratio of Δ G 298 K °| H 2 + 0.5 O 2 → H 2 O for the H 2 produced to the solar power input), when using a solar cavity-receiver operated at 2300 K and subjected to a solar flux concentration ratio of 5000.
Journal ArticleDOI
Concentrating solar thermal power and thermochemical fuels
TL;DR: In this article, the underlying principles of concentrating solar radiation and the latest technological advances and future prospects of solar thermal power and thermochemical fuel production are reviewed and discussed. But the authors focus on concentrating solar energy provides a virtually unlimited source of clean, non-polluting, high-temperature heat.
Journal ArticleDOI
Syngas production by simultaneous splitting of H2O and CO2via ceria redox reactions in a high-temperature solar reactor
TL;DR: In this paper, a solar cavity-receiver containing porous ceria felt is directly exposed to concentrated thermal radiation at a mean solar concentration ratio of 2865 suns, and the syngas composition is experimentally determined as a function of the molar co-feeding ratio H2O:CO2 in the range of 0.8 to 7.7.
