NOVELTY - A method (M1) of generating energy, involves: reacting a liquid compound capable of producing hydrogen and containing organic metal hydride with a metal substrate to produce hydrogen gas, and utilizing the hydrogen gas.    USE - For hydrogen production for generation of energy in hydrogen consuming device e.g. combustible engines and fuel cells, an automobile (claimed), filling stations, fuel delivery truck and pipelines and other hydrogen powered vehicle.    ADVANTAGE - The devices and methods are inexpensive, but efficient and lightweight and practical for use on-board hydrogen powdered vehicles.    DETAILED DESCRIPTION - A method (M1) of generating energy, involves: reacting a liquid compound capable of producing hydrogen and having a formula R-XH with a metal substrate to produce hydrogen gas and utilizing the hydrogen gas.    R = T;    T = (aryl)alkynyl, (hetero)alkyl, optionally substituted alkenyl, (hetero)aryl, alkoxy, cycloalkyl, heterocyclic, alkylaryl, arylalkyl, arylalkenyl, arylene and/or oxyarylene group;    X = sulfur, oxygen, selenium or hydrogen.    INDEPENDENT CLAIMS are included for the following:    (1) a method of storing and producing hydrogen for use in generating energy, involving either (M2) reacting a liquid compound (A) capable of producing hydrogen and having a formula R1-X'H with the metal substrate to produce hydrogen gas and R1-X' bound to the metal substrate and collecting the hydrogen gas; or (M3) reacting a liquid compound capable of producing hydrogen and having a formula R1-XH, with the metal substrate to produce hydrogen gas and a spent compound (a2) comprising R'2-XH (where R'2 is dehydrogenated relative to R1) and/or R'3X, (where R'3 is dehydrogenated relative to R1) and collecting the hydrogen gas;    (2) a device (D1) for producing hydrogen for generating energy, comprising: a storage reservoir to contain a liquid compound capable of producing hydrogen and having a formula either R-X'H or R1-XH; and a metal substrate to react with the liquid compound to produce either an R-X' compound bound to the metal substrate and hydrogen gas; or hydrogen gas and (a2) respectively;    (3) an automobile comprising a hydrogen consuming device and (D1);    (4) a method of regenerating a compound capable of producing hydrogen from a spent compound, involving receiving the spent compound from (D1) and reacting the spent compound with hydrogen to produce a compound of formula R-X'H or R1-XH thus regenerating the compound capable of producing hydrogen from the spent compound; and    (5) an assembly for producing and utilizing hydrogen, comprising: a first unit for producing hydrogen and a second unit for utilizing hydrogen to generate energy. The first unit comprise a storage reservoir adapted to contain the liquid compound capable of producing hydrogen and having a formula R-X'H/R1-XH and the metal substrate to react with the liquid compound to produce either an R-X' compound bound to the metal substrate and hydrogen gas or the hydrogen gas and (a2).
