Abstract: A process for forming lithium hydride for use in storing and producing hydrogen is presented. The process includes reacting lithium oxide with water to form a regenerated lithium hydroxide and reacting the regenerated lithium hydroxide with magnesium to form magnesium oxide and a regenerated lithium hydride. The magnesium oxide can be regenerated to form magnesium. The process can further include reacting lithium hydride to form hydrogen and lithium oxide. Such hydrogen production can include reaction between lithium hydride and lithium hydroxide, and/or reaction between lithium hydride and water.
