Abstract: A method for generating hydrogen from a mixture of nitrogen containing borane compound and active metal borohydride reactants uses a catalyst-free water vapor driven hydrothermolysis process. The method involves mechanically mixing a selected ratio of nitrogen containing borane compound such as ammonia borane and an active metal borohydride such as sodium borohydride to produce a mixture, combining the mixture with a water vapor source, and heating the mixture and water vapor source to a temperature within a near ambient temperature range of 30° C. to 104° C., until a product gas comprising hydrogen is released. The heating can be at a constant temperature or at increasing temperatures. Water vapor and impurities are removed from the product gas to produce purified hydrogen gas.

Abstract: The hydrogen storage product comprises one or more reduced-graphene oxide layers functionalized with a boron species and decorated with an alkali or alkaline earth metal. Each layer of the structure further comprises boron-oxygen functional groups comprising oxygen atoms bonded to boron atoms. The hydrogen storage product has a composition suitable for physisorption of hydrogen molecule, and operates to reversibly store hydrogen under operating conditions of low pressure and ambient temperature.
