TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The sorbent comprises a deliquescent hydride, desiccant and deliquescent salt, preferably aluminates, calcium chloride, zinc chloride, lithium chloride, sodium acetate, potassium acetate and/or trimethylamine n-oxide. The hydrogen releasing agent comprises: a compound (preferably a hydrolyzing agent) capable of producing hydrogen in a reaction with the reagent (preferably water), a mixture of a hydride and/or a metal, or a combination of a hydrides and metals. The sorbent and the hydrogen-releasing agent comprise the same compound.Preferred Process: The process further comprises the step of controlling the rate of hydrogen liberation; the step of varying the amount of the reagent exposed to the composition; the step of converting the sorbent from a substantially non-reactive sorbent to a hydrogen-releasing sorbent, where the conversion step is effected by catalyzing the sorbent; and the step of combining at least two sorbents and at least two hydrogen releasing agents in the composition. The reagent is provided in a carrier medium (preferably air, inert gas or vacuum). The process further comprises: the steps of catalyzing the sorbent to function as a sorbent and hydrogen-releasing agent; providing a second catalyzed hydrogen-releasing agent; and reacting the second catalyzed hydrogen-releasing agent with the reagent from the catalyzed sorbent to liberate the hydrogen.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The sorbent is catalyzed. The hydrogen-releasing agent is catalyzed. The reagent is capable of generating hydrogen in reaction with the hydrogen-releasing agent. The reagent is water (preferred), alcohol, ammonia, organic vapor, methane, ethane, natural gas, hydrogen-containing vapor and/or gas. The sorbent is a compound having deliquescent or hygroscopic properties. EXAMPLE - Magnesium powder was mixed with the catalyst (prepared from titanium hydride and copper in a process of ball milling with methanol) and ball milled for less than 1 hour to give good distribution of the catalyst over magnesium powder. Hydrogenation of the catalyzed magnesium was performed in the automated, computer controlled gas titration system to produce catalyzed magnesium hydride. The powders of the catalyzed magnesium hydride and calcium chloride were mixed together in the glove box under protective atmosphere of argon with oxygen (less than 1 ppm) and water (less than 1 ppm). The mixture was subsequently exposed to air at the relative humidity of 50 % to give hydrogen-generating composition comprising calcium chloride (sorbent) and catalyzed magnesium chloride (hydrolyzing component).
