Published at International Journal of Hydrogen Energy – Process behavior analysis of a fixed-bed solar reactor for hydrogen generation via two-step thermochemical redox cycling

Abstract: The two-step solar-thermochemical cycle process for water splitting is a promising technology for hydrogen generation with very high theoretical efficiencies. This study investigates the operational behavior of a prototype solar reactor with thermal power of 250 kW. A multi-physical reactor model is used for analyzing the dynamical process behavior of the reactor’s porous metal …

Published at Chemical Engineering Journal – A novel rotary-cavity reactor for sustainable solar metallurgy: Design and experimental demonstration of direct reduction of iron ore

Abstract: This study addresses the direct reduction of iron ore with hydrogen and solar energy as the process heat source for clean iron/steel making and decarbonation of the metallurgical process. A novel rotary-type solar reactor was designed, constructed and tested for demonstration of hydrogen-based direct iron ore reduction under real direct solar irradiation. Such a …
