Abstract
Provided herein are methods and systems of producing hydrogen using ammonia borane, which has a high hydrogen density while being stable and easily stored. Ammonia borane may be exothermically reacted with a strong oxidizer, such as a mixture of hydrogen peroxide and water. The reaction between ammonia borane and the strong oxidizer may occur spontaneously and may produce heat. Unreacted ammonia borane may be exposed to and thermally decomposed using the heat produced during the exothermic reaction between ammonia borane and the strong oxidizer. The heat may be retained by performing the reactions in a vessel or reactor including a material capable of retaining the heat. A high gravimetric hydrogen yield is obtained from the reaction of ammonia borane with hydrogen peroxide and the thermal decomposition of unreacted ammonia borane. Hydrogen production using the methods and systems may yield a high gravimetric hydrogen content of at least about 10%.
