  • Patent number: 8167122
    Abstract: An apparatus for storage of compressed hydrogen gas is provided. The apparatus includes a sealed housing having an outlet pipe coupled to the housing and equipped with a controllable discharge valve. The sealed housing defines a chamber that includes a cartridge comprising an assembly of at least two different types of micro-containers configured for accumulating and storing said compressed hydrogen gas. The apparatus also includes a hydrogen liberating tool configured for controllable liberating the hydrogen gas from the cartridge into a volume of the chamber that is not occupied by the cartridge. The apparatus is controlled by a control system operatively coupled to the controllable discharge valve and the hydrogen liberating tool, and configured for controlling operation thereof.

  • Patent number: 7870878
    Abstract: An apparatus for storage and liberation of compressed hydrogen or other gases is provided. The apparatus includes a housing defining a chamber that includes a cartridge comprising an array of hollow microcylinders defining cavities for storage compressed gas. Each microcylinder has at least one end sealed with a plug made of an easily meltable alloy. The apparatus also includes a gas liberating tool configured for controllable liberating the gas from the cartridge into the chamber; and a control system operatively coupled to the discharge valve and liberating tool, and configured for controlling operation thereof. According to another aspect of the invention, there are provided a system and method for filling a cartridge having an array of hollow microcylinders having open ends. The filling includes placing the cartridge into a chamber of an autoclave, and compressing the gas in the chamber, thereby providing permeation of the gas through the open ends into cavities of the microcylinders.

  • Patent number: 7648567
    Abstract: A hydrogen accumulation and storage material and a method of forming thereof are provided. The material comprises a plurality of various-sized and at least partially permeable to hydrogen microspheres bound together to form a rigid structure in which a diameter of the microspheres is reduced from a center of the structure towards edges of the structure. An outer surface of the rigid structure can be enveloped by a sealing layer, thereby closing interspherical spaces.
