| Outline of Final Research Achievements |
In order to develop the prototype reactor system for water splitting to produce solar hydrogen by utilizing concentrated solar radiation in world sun-belt regions with abundant insolation, two types of the solar reactors (the conical foam device reactor type and the particle fluidized bed reactor type) for two-step thermochemical water splitting cycle using metal oxide redox pair (reactive ceramics) are developed. In this work, solar demonstrations of 30-40kWth scale reactors have proven that the two reactor concepts can split water to produce hydrogen utilizing concentrating solar thermal energy. For industrial application, the fluidized reactor system concept is suitable for MWth-scale solar hydrogen production plants since the hydrogen productivity per cycle is very high. On the other hand, the foam device reactor system concept is suitable for around 500kWth small hydrogen production systems.
