TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Material: The hydrogen precursor material is lithium hydride (LiH), lithium aluminum hydride (LiAlH4), lithium borohydride (LiBH4), sodium hydroxide (NaH), sodium aluminum hydride (NaAlH4), sodium borohydride (NaBH4), magnesium hydride (MgH2), magnesium borohydride (Mg(BH4)2), potassium hydride (KH), potassium borohydride (KBH4), calcium hydride (CaH2), calcium borohydride (Ca(BH4)2), ammonia borohydride (NH3BH3), aluminum, and/or magnesium. The reactive material is liquid water, water vapor, aqueous solutions, liquid ammonia, gaseous ammonia, acidic solutions, and/or basic solutions. The treatment material is liquid water, water vapor, aqueous solutions, liquid ammonia, gaseous ammonia, acidic solutions, basic solutions, and/or carbon dioxide.    TECHNOLOGY FOCUS - MECHANICAL ENGINEERING - Preferred Component: The system has the first inlet line adapted to introduce a reactive material into the reactor vessel and the second inlet line adapted to introduce a treatment material into the reactor vessel. The system includes a heater adapted to heat the contents of the reactor vessel, a mixer adapted to mix the contents of the reactor vessel, a first storage vessel adapted to store the reactive material and having an outlet connected to the first inlet line, a second storage vessel adapted to store the treatment material and having an outlet connected to the second inlet line, and a storage vessel adapted to store the treatment material and having an outlet connected to the second inlet line. The first inlet line includes a flow control device to control the flow of the reactive material. The second inlet line includes a flow control device to control the flow of the treatment material. The two storage vessels are joined to the reactor vessel to form an integrated system.    TECHNOLOGY FOCUS - METALLURGY - Preferred Material: The hydrogen precursor material can be magnesium-iron alloys.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Material: The reactive and the treatment materials can be liquid alcohols and/or gaseous alcohols.
