Disclosed is a method for producing a hydrogen-generating fuel, the hydrogen-generating fuel obtained, a method for producing hydrogen from the fuel, a device for carrying out the production method, a method for operating the device, and a hydrogen-based fuel obtained by use of the production method. The production method is characterized in that it consists in mixing, in a liquid, particles of one or more metals which are corrodible by a basic chemical substance or an acidic chemical substance for the purpose of producing hydrogen, the particles being kept in suspension in the liquid, and the mixture composed of the liquid and the particles being chemically stabilized so as to prevent chemical reaction between the liquid and the particles.

Alloys comprised of a refined microstructure, ultrafine or nano scaled, that when reacted with water or any liquid containing water will spontaneously and rapidly produce hydrogen at ambient or elevated temperature are described. These metals, termed here as aluminum based nanogalvanic alloys will have applications that include but are not limited to energy generation on demand. The alloys may be composed of primarily aluminum and other metals e.g., tin bismuth, indium, gallium, lead, etc. and/or carbon, and mixtures and alloys thereof. The alloys may be processed by ball milling for the purpose of synthesizing powder feed stocks, in which each powder particle will have the above-mentioned characteristics. These powders can be used in their inherent form or consolidated using commercially available techniques for the purpose of manufacturing useful functional components.

Systems and methods related to deployable hydrogen reactors are described. In some embodiments, a system (e.g., a balloon system) may include a reaction chamber immersed in a body of water. By permitting a flow of water from the body of water into the reaction chamber, a reaction between a reactant and the water may be carried out to produce one or more lifting gases (e.g., hydrogen gas), which can be employed to subsequently inflate and launch the system in an automated fashion.
