Journal ArticleDOI
Solar Thermochemical Water-Splitting Ferrite-Cycle Heat Engines
TL;DR: In this paper, a two-step solar-driven thermochemical heat engine based on iron oxide and iron oxide mixed with other metal oxide (ferrites) working materials is proposed.
Journal ArticleDOI
Carbon Dioxide Reforming of Methane in a Solar Volumetric Receiver-Reactor: The CAESAR Project.
TL;DR: In this paper, a volumetric absorber was used for solar reforming of methane with CO 2 with a direct absorption receiver/reactor on a parabolic dish capable of 150 kW solar power.
Journal ArticleDOI
Solar reforming of methane in a direct absorption catalytic reactor on a parabolic dish: I—Test and analysis
TL;DR: The CAtalytically Enhanced Solar Absorption Receiver (CAESAR) test was conducted to determine the thermal, chemical, and mechanical performance of a commercial-scale, dish-mounted, direct catalytic absorption receiver (DCAR) reactor over a range of steady state and transient (cloud) operating conditions as discussed by the authors.

Solar Thermochemical Water-Splitting Ferrite-Cycle Heat Engines
TL;DR: In this article, a two-step solar-driven thermochemical heat engine based on iron oxide and iron oxide mixed with other metal oxides (ferrites) was proposed, where two sets of moving beds of ferrite reactant material in close proximity and moving in opposite directions to overcome a major impediment to achieving high efficiency.
