Title: Hydrogen storage container

Abstract

An apparatus and system is described for storing high-pressure fluids such as hydrogen. An inner tank and pre-stressed concrete pressure vessel share the structural and/or pressure load on the inner tank. The system and apparatus provide a high performance and low cost container while mitigating hydrogen embrittlement of the metal tank. System is useful for distributing hydrogen to a power grid or to a vehicle refueling station.

  • Oxygen is incorporated into an FeTiMn granulate in an amount sufficient to form double oxides of titanium and manganese therein, but insufficient to form oxides containing iron. As the result, the granules are embrittled, favoring the formation of microcracks to such an extent that activation of the granules by hydrogen takes place, after initial evacuation, at room temperature, after which the granulate can be used in a pressure container for storage and discharge of hydrogen and/or deuterium over long periods of operation. The oxygen content is to be kept in an atomic ratio with reference to the manganese content ofmore » the alloy lying between 1:3 and 1:3.5 and the ratio of titanium not bound by formation of a metal oxide to the iron should be equal to or greater than 1:1 on an atomic basis, with the FeTi content of the alloy constituting 90 to 95% by weight of the alloy.« less
  • The activation of a mass of metal granules capable of storing hydrogen with the formation of hydride in a pressure vessel, instead of having to be activated before use by repeated heating in a hydrogen atmosphere followed by cooling and evacuation before the next heating, is activated in the pressure vessel used for storage by first heating a small portion of the granulate to the necessary activation temperature and then allowing the heat developed by the activation of that portion to produce the activation of the remainder of the granulate. It is found that it thus possible to provide completemore » activation with only one heating step. The small portion that is first activated may be a part of the granulate that is of a different composition that is easier to activate, for example, lani5, which can be activated at room temperature, or iron-titanium alloys that are capable of activation under 100/sup 0/ C. Alternatively, the entire mass of granulate may be selected for its hydrogen-storage capability rather than its ease of activation and a small part thereof can be activated first by means of a high temperature (Up to 800/sup 0/ C.) generated in a very small source of heat, as by a platinum wire electric heater, turned on for only 10 or 20 minutes, after which the activation produced provides enough heat for activating the remainder of the granular material.« less
  • A device for transporting and changing sources is described that comprises an elongated flexible carrier for the radioactive material with a unitary shielding body, a changer head mounted on the body with connectors for tubular conduits, and two channels within the body closed at one end and curved toward the open end so as to obstruct any straight path.
