  • Publication number: 20080221373
    Abstract: A solid clathrate hydrate comprising lactate anion and a calcium cation. The clathrate hydrate serves as a sponge that can be used to store a gas such as hydrogen, methane, oxygen, or carbon dioxide. The presence of carboxylate anion (lactate) stabilizes the clathrate so that it is solid and stable at relatively mild temperatures and pressures.

  • Publication number: 20080168776
    Abstract: A gas storage system that stores a gas by cryo-adsorption on high surface materials. The gas storage system includes an outer container having insulated walls and a plurality of pressure vessels disposed therein. Each of the pressure vessels includes a high surface material. A manifold assembly distributes the gas under pressure to the pressure vessels where the gas is adsorbed by cryo-adsorption using the high surface materials. A cooling fluid is provided within voids between the pressure vessels to remove heat as the pressure vessels are being filled with the gas.

  • Patent number: 7392657
    Abstract: ozone is dissolved ozone in a liquid cryogen. A container containing a liquified cryogen is provided. A gaseous stream of ozone is allowed to flow into at least one adsorption unit containing an adsorbent material, thereby adsorbing ozone thereupon. The cryogen is allowed to flow from the container to the at least one adsorption unit and therethrough thereby extracting an amount of the ozone adsorbed upon the adsorbent material, wherein the cryogen is in either a liquid, gaseous or supercritical phase as it flows through the adsorption unit. ozone becomes dissolved in the cryogen.

  • Patent number: 7257952
    Abstract: The methods and apparatus for transporting compressed gas includes a gas storage system having a plurality of pipes connected by a manifold whereby the gas storage system is designed to operate in the range of the optimum compressibility factor for a given composition of gas. The pipe for the gas storage system is preferably large diameter pipe made of a high strength material whereby a low temperature is selected which can be withstood by the material of the pipe. Knowing the compressibility factor of the gas, the temperature, and the diameter of the pipe, the wall thickness of the pipe is calculated for the pressure range of the gas at the selected temperature. The gas storage system may either be modular or be part of the structure of a vehicle for transporting the gas. The gas storage system further includes enclosing the pipes in an enclosure having a nitrogen atmosphere. A displacement fluid may be used to offload the gas from the gas storage system.

    Abstract: This invention provides for an apparatus and a method for operation of a cryogenic hydrogen storage system that contains a porous medium configured to adsorb hydrogen. The hydrogen storage and supply system includes a hydrogen source apparatus and a cryosorptive storage apparatus. Methods and devices that allow for an energy efficient filling of the cryosorptive apparatus from the hydrogen source apparatus are described. The cryosorptive hydrogen storage apparatus is filled with cold, pressurized hydrogen. During the course of filling, heat is generated in the cryosorptive storage device by the process of hydrogen adsorption on to the host medium. Methods and devices are provided for the removal the generated heat and the warm hydrogen. Further provided are devices and methods for the capture and recycle of escaped hydrogen within the hydrogen source apparatus.

  • Patent number: 7028488
    Abstract: A method of dispensing a liquid material from a source container which includes a blend of fluids of a first composition that normally fractionate upon boiling. A material of a second composition (different than that of the first composition) and capable of maintaining the first composition of the material remaining in the source container is added to the source container during the transfer of liquid from the source container. This addition of a material of a second composition to the supply container during the transfer can minimize and/or even eliminate fractionation of the liquid in the source tank.
