This invention uses nanoparticles to broaden the range of economic materials, improve performance across this broader range, and thereby lower costs of hydride and other storage systems. Nanoparticles can have dramatically different mechanical, chemical, electrical, thermodynamic, and/or other properties than their parent (precursor) materials. Because of this fundamental characteristic, nanophase materials can greatly improve the range of possibilities of materials selection, performance, cost, and practicality for hydride storage systems, advancing the early commerciality of such systems for hydrogen fuel cells or other applications. Among such hydrogen storage improvements are cheaper and better-performing metals, alloys, and/or compounds; lower weight; and reduced storage volumes.

1. A material for storing hydrogen as a hydride, wherein the material comprises: an aggregate of nanomaterials, wherein the aggregate has an average critical dimension of 15 to 200 nanometers. 2. A material for storing hydrogen as a hydride, wherein the material comprises: a mixture of nanoparticles capable of storing hydrogen as a hydride, wherein essentially all of the particles have at least two dimensions of at least about 2 nanometer and no more than about 200 nanometers, wherein the nanoparticle is in a liquid. 3. A method of using a material for storing hydrogen as a hydride, comprising: (1) contacting the material with hydrogen in the presence of an additional gas or vapor, wherein the material comprises a mixture of nanoparticles, wherein essentially all of the particles have at least two dimensions of at least about 2 nanometer and no more than about 200 nanometers so that at least part of the material reacts with the hydrogen to form a hydride; and (2) heating the hydride to release at least some of the hydrogen from the hydride.
