A composite material 100 of the present invention includes silicon particles or silicon fine particles 10 capable of generating hydrogen, and a metal element (iron (Fe)) 20 supported on, or attached or adsorbed to at least a part of surfaces of the silicon particles or silicon fine particles 10, or chemically bonded to the surfaces. According to the composite material 100, it is possible to exhibit a capability of generating hydrogen much higher than that of silicon particles or silicon fine particles 10 on which the metal element 20 is hardly supported or to which the metal element 20 is hardly attached or adsorbed, or silicon particles or silicon fine particles 10 which are hardly chemically bonded to the metal element.

The present invention relates to a composite material for hydrogen storage based on metal hydrides and to a method of operating a hydrogen storage system based on metal hydrides capable of releasing and absorbing hydrogen. Such hydrogen storage systems based on metal hydrides may be applicable as a fuel source for a fuel cell. The composite material for hydrogen storage comprises a powder or pellets of a hydride and a phase changing material (PCM), wherein the PCM is an encapsulated phase changing material (EPCM) which is homogeneously dispersed within the powder or pellets of the hydride.

The present relates to a carbon material having a 3D structure and made of graphene oxide and carbon nanotubes, characterized in that the 3D structure consists in that the carbon nanotubes are located with some agglomeration between the graphene oxide layers so as to extend the spacing between the graphene oxide layers.

A storage system for storing solid hydrogen includes: a plurality of storages including two or more types of solid hydrogen storage materials having different magnetic intensities; a storage container configured to accommodate the storages; and a coil disposed inside the storage container and configured to apply a variable magnetic field to the storages accommodated in the storage container.

Described herein are compositions and methods for the chemical storage and release of hydrogen gas. The described compositions may be useful as fuel additives for hydrogen consuming applications, including aviation. The provided compositions are flexible and can be tailored to be lightweight, have high energy capacity, have various methods of activation and rapidly release the stored hydrogen.
