This technology began as an undergraduate research project and resulted in composition and process that produces the cleanest hydrogen and the cleanest alumina available. The composition is generated by mixing gallium and aluminum in a molar ratio of 3 gallium: 1 aluminum. This alloy results in the formation of aluminum nanoparticles within the gallium that reacts vigorously with water to generate hydrogen and aluminum oxide (Al2CO3 or alumina). The reaction can be performed at room temperature with no electrical or other energy input. Importantly, all the gallium used in the initial alloy can be recovered after the reaction is complete and reused indefinitely.
The work began with the idea that waste aluminum can be used and the reaction has been performed using waste aluminum foil and soda can lids as aluminum sources. Similarly, no purified water is required: tap water, gray water, and saltwater have also been used.
Hydrogen is a key fuel for future energy storage. Currently, most hydrogen is produced directly from hydrocarbons, resulting in the production of carbon dioxide. Catalytically produced hydrogen (from the evolution of hydrogen from water) does not produce carbon dioxide but requires a great deal of electrical power which is difficult to provide renewably. It also requires relatively pure water, which increases the cost and energy requirements.
Alumina powder is a widely used component in many industrial processes. Currently, alumina powder is produced from mined bauxite via the Bayer process, which requires enormous amounts of heat, the release of significant amounts of carbon dioxide, huge volumes of highly corrosive chemicals, and generates "red mud" which is a useless and dangerous environmental waste product.
