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.

With regards to solar thermochemical two-step water splitting cycle using reactive ceramic as a highly-active redox material for producing hydrogen from water, prototype fluidized bed reactor was developed and tested for hydrogen production from water using high-temperature solar heat. This reactor allows that oxygen and hydrogen are simultaneously produced and separated inside the reactor. Thus, the reactor can realize a single-process of successive two-step reactions in a single fluidized bed reactor. An irradiation test by 5kW sun-simulator showed that oxygen and hydrogen were simultaneously produced in the single-process. I did an application for a domestic patent for method and device using this reaction system for solar thermochemical water splitting to produce hydrogen.

本研究では,世界のサンベルト地域で得られる1000～1500℃の高温太陽集熱をエネルギー源として反応性セラミックによる二段階水熱分解サイクルによってソーラー水素の製造を行う2つの異なるコンセプトのソーラー反応器(発泡体デバイス型反応器および内循環流動層型反応器)のプロトタイプを3～5kWで作製し,これを太陽炉シミュレータあるいはパラボラディッシュ型太陽集光器(韓国インハ大学所有)を用いて性能評価することを目的とする。22年度は下記の研究成果が得られた。
1)発泡体デバイス型反応器については下記の成果が得られた。
発泡体デバイス反応器の2号器を作製し,新潟大の3kW太陽炉シミュレータによる擬似太陽集光による試験と,韓国インハ大学の5kWディッシュ型太陽集光器でのフィールド試験を並行して行った。反応体である発泡体でデバイスの反応性セラミック担持量等の合成条件を検討することにより,従来よりも発泡体デバイスの耐久性を向上させこの反応システムにおいて二段階水分解反応のサイクル化を行なうことが出来た。
2)内循環流動層型反応器については下記の成果が得られた。
内循環流動層反応器については,二段階サイクル反応を一段階プロセスとして実施できる従来にない画期的な反応器を考案している。,より安定に水素生成を行なうことを目的として反応器の設計改良を行い,これを新規に導入した5kW太陽炉シミュレータにより擬似太陽集光による性能試験を行った。同時に流動層に用いる反応性セラミック粒子の改良も行った結果,従来よりも一段階プロセスとして安定・定常的に水素生成を維持することに成功した。これに関しては国際特許出願を行なった。

本研究では,従来の高温太陽集熱をエネルギー源とする二段階水熱分解サイクルの反応媒体である水熱分解性セラミックの熱活性に,光半導体触媒の光活性を添加し,水熱分解サイクル反応を低温化することに挑戦した。初年度の研究により,研究代表者が見出した水熱分解性セラミックのFe_3O_4/ジルコニア担持体(Fe含有立方晶ジルコニア,あるいはFe_3O_4/単斜晶ジルコニア)にNiOをドープした水熱分解性セラミック粉体合成に成功し,さらにスピンコーティング法等の方法を応用して,この粉体を材料とした小型発泡体デバイスを作製することにも成功した。さらに,擬似太陽集光を直接デバイスに照射して2段階水分解反応を行う反応デバイスの活性試験を行い,NiOドーブによりデバイスの反応活性が向上することを確認した。今年度は下記の研究を実施する。今年度は下記の研究成果を得た。
1)作製の成功したFe-Ni含有立方晶ジルコニア発泡体デバイスについて,立方晶ジルコニアに対するNiOドープ量,またFeOドープを変化させ,反応デバイスの反応活性の向上を試みた。反応試験を太陽炉シミュレータで行い,FeO:NiO=2:1のドープ量が反応活性に対して最適なドープ量であることを見出した。
2)NiO同様に熱力学的見地,および光半導体活性の見地からCoOがFe_3O_4/ジルコニア担持体の反応活性を熱-光ハイブリット活性化によって高めると期待されるため,同様の手法でCoOをドープしたFe_3O_4/ジルコニア担持体粉体を合成し,その水熱分解活性を,赤外線イメージ炉を熱源として試験した。反応活性はほぼNiOドーブ型と同様の活性を得ることが出来た。

In this research project, we have developed reactive ceramic devices to be used in solar thermochemical two-step water splitting cycle, for utilizing high-temperature solar heat in sun-belt regions. The main results are listed below :
1. Development of High Reactive Ceramic Powders
We investigated the other-metal doping effect on the ferrite supported on zirconia and found that Ni_<0.1>Fe_<2.0>O_4/ZrO_2 is the most reactive powder. On the other hand, we also found that, when yttrium-cubic-stabilized zircionia or YSZ is used as support instead of normal monoclinic zirconia, an iron-containing YSZ or Fe^<2+>-YSZ is formed by a high-temperature reaction between YSZ, and FeBBB_<3B>OB_<4B> supported on the YSZ at 1400℃ in an inert atmosphere, and that the FePPP^<2+P>-YSZ then reacts with steam and generate hydrogen at 1000-1100℃, to form FeP^<3+P>-YSZ that is re-activated by a thermal reduction in a separate step at temperatures above 1400℃ under an inert atmosphere.
2. Preparation and Reactivity Test of Reactive Devices
Zirconia foams coated with the Ni<1.0>Fe_<2.0>O4/ZrO_2or Fe_3O_4/YSZ particles were prepared as reactive devices and examined on reactivity for two-step water splitting cycle being performed alternately at temperatures between 1100 and 1400℃. Hydrogen successfully continued to be produced in the repeated 13-30 cycles, but foam device had cracks and broken after the repeated cycles. Ceramic foams with a higher thermal shock resistance, such as SiC foam, should be used as the matrix of the reactive devices.
3. Coating of SiC foam with Ziconia and Performance test for Thermal Resistance under Solar Irradiation
The SiC foam matrix was successfully coated with zirconia layers before FeBB_<3BB>OBB_<4BB> is applied on the matrix. On the other hand, the SiC foam matrix was examined on thermal resistance under solar irradiation using solar furnace and, as the results, we found that the SiC foam matrix has a good thermal resistance.
