One object of the present disclosure is to provide a production method of magnesium hydride that is free of carbon dioxide and has high production efficiency, a power generation system that does not emit carbon dioxide or radiation using magnesium hydride, and an apparatus for producing magnesium hydride; therefore, the method for producing magnesium hydride of the present disclosure comprises a procedure for irradiating a magnesium compound different from magnesium hydride with hydrogen plasma, and a procedure for depositing a magnesium product containing magnesium hydride on a depositor for depositing magnesium hydride disposed within the range in which hydrogen plasma is present, wherein the surface temperature of the depositor is kept no more than a predetermined temperature at which magnesium hydride precipitates.

The present disclosure relates to a composite for hydrogen storage formed through lithiation and a method of preparing the same.

Processes for producing a metal superhydride include obtaining a metal or metal alloy electrode comprising one or more metal atoms, obtaining an electrolyte comprising hydrogen atoms, the electrolyte configured to kinetically suppress a hydrogen evolution reaction in the metal electrode, disposing the metal electrode in the electrolyte, applying pressure to the metal electrode and the electrolyte while the metal electrode is disposed in the electrolyte, and forming, based on applying the pressure, a metal superhydride comprising a plurality of hydrogen atoms of the electrolyte being bonded to each of the one or more metal atoms of the metal electrode. Generally, the metal superhydride is stable at a pressure less than 100 gigapascal (GPa).

A storage medium and an inert material, either integrated into the storage medium or existing as a separate phase in the storage medium, form a storage structure. The inert material at least partially contains or is formed by a polymorphous inert material. The polymorphous inert material has at least one polymorphous phase transition in the range between ambient temperature and maximum operating temperature of the solid electrolyte battery. The polymorphous phase transition induces a distortion of the lattice structure of the inert material, thus causing a change in the specific volume and acting on the surrounding grains of the storage medium. A mechanical coupling of the stresses triggered by the phase transition of the inert material causes the neighboring grains of the storage medium to break apart, such that new reactive zones become available in the storage medium, thereby regenerating the solid electrolyte battery.
