Abstract:
An adsorbence-based gas storage system includes a pressure vessel containing a granular gas adsorbent material, for example, an activated carbon or a metal-organic framework. The system may be configured to store natural gas or methanol. The pressure vessel includes a pressure release device, and an inlet/outlet valve for passage of gas into and out of the pressure vessel. A microwave or RF generator is configured to selectively heat the adsorbent material. In one embodiment the generator is connected to the pressure vessel through one or more waveguides, and at one or more locations along the pressure vessel. A sensor, for example, a temperature sensor, monitors the temperature in the pressure vessel. A computing device uses the sensor data to control the generator to selectively heat the adsorbent material.
Abstract:
Microtanks are formed in capped holey fibers. Holey fiber is composed of a shell, a porous layer and a hollow core. Compressed gas can be stored in plurality of microtanks at elevated pressure. A method of storing and releasing hydrogen gas in or out of a plurality of microtanks is also disclosed.
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.
