Producing method for producing magnesium hydride, power generation system using magnesium hydride, and producing apparatus for producing magnesium hydride

A power generation method using magnesium hydride comprising:

• producing a magnesium product containing magnesium hydride from a magnesium chloride,
• generating hydrogen from the magnesium product,
• supplying the generated hydrogen to a power generation unit to generate power, and
• producing the magnesium chloride from a by-product containing magnesium after generating the hydrogen,
• wherein the by-product contains magnesium hydroxide or magnesium oxide,
• wherein producing the magnesium chloride comprises:
• reacting the by-product with hydrochloric acid to obtain magnesium chloride hydrate, and
• dehydrating the hydrate, and
• wherein producing the magnesium product is performed by a method for producing magnesium hydride comprising:
• irradiating a magnesium chloride with hydrogen plasma, and
• depositing the magnesium product containing magnesium hydride on a depositor for depositing the magnesium hydride disposed within a range where the hydrogen plasma is present,
• wherein a surface temperature of the depositor is kept no more than a predetermined temperature at which the magnesium hydride precipitates.
