<p>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 [&#8230;]</p> <p>The post <a href="https://www.solarpaces.org/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/">Published at International Journal of Hydrogen Energy &#8211; Process behavior analysis of a fixed-bed solar reactor for hydrogen generation via two-step thermochemical redox cycling</a> appeared first on <a href="https://www.solarpaces.org">SolarPACES</a>.</p>

<p>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.
