Publication number: 20210246020Abstract: A method uses a chemical system to generate hydrogen gas. The chemistry involves a two-step reaction. In the first step, an alkaline hydride reacts with water to produce a hydroxide and hydrogen. In the second step, the hydroxide reacts with aluminum to produce even more hydrogen. The fuel is composed out of a mixture of powders of the alkaline hydride and aluminum. The fuel is encapsulated in a water soluble capsule for easy dispensing and protection against short time exposure to moisture. For large scale systems, the fuel is mixed with a low hydrophilicity ionic liquid to make it into a slurry that can be dispensed into a reaction chamber. The generation system comprises a tank, a pump, a first tube, a second tube, one or more capsules, a tank sensor assembly, and a processing system. The method comprises the steps of dispensing the capsules or the slurry in the tank; supplying water to the tank; and collecting hydrogen gas from the tank.Type: ApplicationFiled: February 11, 2020Publication date: August 12, 2021Applicant: Xnrgi, Inc.Inventors: Saroj Kumar Sahu, Gerard Christopher D'Couto
