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 a plurality of cylindrical voids containing 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. According to another aspect of the invention, there are provided a system and method for filling the cartridge. The filling includes vacuumizing a chamber into which the cartridge is placed; preparing the cartridge in order to let the hydrogen gas diffuse into the cylindrical voids; and controlled hydrogen gas compressing in the chamber over a predetermined compression time interval until the pressure in the chamber reaches a predetermined pressure value.
Abstract:
The invention is a reactor for solid waste treatment and energy recovery from organic compounds in solid waste. The reactor comprises an updraft gasification shaft and a plasma melting chamber. The gasification shaft is constructed with an upper portion comprised of a cylindrical section and a lower portion comprised of a conical section whose interior wall slopes upwards and inwards relative to the vertical axis of the reactor until it smoothly joins the cylindrical section. The plasma melting chamber has an interior with a circular cross-section and comprises at least one plasma torch and a conical wedge having the shape of a truncate cone with its apex pointing upward located at its center.
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.
Abstract:
The present invention provides a hydrogen loaded solid substance comprising at least 10% w/w of hydrogen. The solid is polycrystalline heat steady substance with large interstructural area, made of carbon and transition metals, carbon and rare earth element, intermetalloid, and/or hydride thereof. Also provided by the invention is a process for loading such solid with hydrogen. The process includes exposing the solid substance to hydrogen pressure of at least 500 Atm at a temperature of at least 1000°C and then cooling at a rate of at least 10°C/sec.
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.
Abstract:
An apparatus for storage and liberation of compressed hydrogen gas is described. The apparatus comprises a storage tank, a pre-volume chamber coupled to the storage tank, a hydrogen liberating tool, and an adapter module coupled to the pre-volume chamber and configured for coupling the pre-volume chamber to a device utilizing the hydrogen gas stored in the storage tank for supplying the hydrogen gas thereto. The storage tank comprises a plurality of arrays of hollow micro-cylinders defining cavities storing compressed hydrogen gas therewithin. Each micro-cylinder has an end sealed with a plug made of an easily meltable alloy having a melting temperature lower than the melting temperature of the micro-cylinder material. The pre-volume chamber is coupled to the storage tank such that the micro-cylinder ends sealed with the plugs are located within a volume of the pre-volume chamber. The hydrogen liberating tool comprises a plurality of heating coils wound around the micro-cylinder ends sealed with plugs. The heating coils are configured for melting the plugs, thereby to controllably liberate the hydrogen gas from the arrays of the micro-cylinders into the pre-volume chamber.
