Abstract
(EN) To provide a new magnesium-recycling hydrogen generation system that may require less energy to produce a raw material for producing a hydrogen generation material while suppressing the reduction of hydrogen production, a magnesium-recycling hydrogen generation system of the present invention includes: a by-product acquisition unit that separates a by-product from a post-reaction solution, which is a solution after reacting with a hydrogen generation material containing a hydrogen-containing magnesium compound that generates hydrogen via a reaction with the solution, to acquire the by-product including more than one type of oxygen-containing magnesium compound that contains oxygen produced by the reaction, a raw material production unit that reacts the by-product with a halogen-containing substance containing halogen and other atoms than the halogen to produce a raw material containing magnesium halide, a hydrogen generation material production unit that reduces the raw material with plasma containing hydrogen to produce the hydrogen generation material, and a hydrogen generator that reacts the hydrogen generation material with the solution to generate hydrogen.
(FR) La présente invention vise à fournir un nouveau système de génération d'hydrogène de type à circulation de magnésium qui peut potentiellement réduire l'énergie nécessaire pour la production d'une matière première pour produire un matériau générant de l'hydrogène tout en réduisant au minimum la réduction du rendement en hydrogène. A cet effet, le système de génération d'hydrogène de type à circulation de magnésium selon la présente invention comprend : une partie d'acquisition de sous-produit, un sous-produit qui contient un ou plusieurs types de composés de magnésium contenant de l'oxygène contenant de l'oxygène produit par la réaction susmentionnée étant séparé pour ainsi acquérir le sous-produit, à partir d'une solution de post-réaction restant après une réaction avec un matériau générant de l'hydrogène, qui contient un composé de magnésium contenant de l'hydrogène générant de l'hydrogène lors de la réaction avec la solution ; une partie de production de matière première, le sous-produit étant mis à réagir avec une substance contenant de l'halogène contenant un atome d'halogène et un atome autre que des halogènes pour ainsi produire une matière première contenant un halogénure de magnésium ; une partie de production de matériau générant de l'hydrogène, la matière première étant réduite avec un plasma contenant de l'hydrogène pour produire ainsi un matériau générant de l'hydrogène ; et une partie de génération d'hydrogène, le matériau générant de l'hydrogène étant mis à réagir avec la solution pour générer ainsi de l'hydrogène.
