Abstract:
The present invention relates to a tank device for storing hydrogen for an aircraft. The tank device comprises an outer tank and an inner tank. The inner tank is held in the outer tank. The outer tank is arranged such that the hydrogen with first physical characteristics can be stored. The inner tank is designed such that the hydrogen with second physical characteristics can be stored. The outer tank is connected to the inner tank such that the hydrogen can be fed to the inner tank from the outer tank. The inner tank is designed such that the hydrogen with the first physical characteristics can be converted to the hydrogen with second physical characteristics. The inner tank is arranged such that the hydrogen comprising the second physical characteristics can be fed to a consumer.

PROBLEM TO BE SOLVED: To provide an apparatus for storage and liberation of a gas such as ultra high pressure compressed hydrogen in a cartridge including a lot of microcylindrical arrays. SOLUTION: A housing 11 forming a chamber 13 is included which has a cartridge 14 including an array 143 of hollow microcylinders forming cavities for storage of a compressed gas. Each microcylinder 143 is sealed with a plug 147 made of an easily meltable alloy. A gas liberating tool 15 liberating the gas from the cartridge 14 to the chamber 13, and a control system 16 coupled to a discharge valve are included. A system and method are provided for filling the cartridge 14 having the array 143 of the hollow microcylinders having open ends. The filling includes: putting the cartridge 14 into a chamber of an autoclave; compressing the gas in the chamber, and thereby providing permeation of the gas into the cavities of the microcylinders through the open ends. Thereafter, the open ends are sealed with the plugs 147 made of an easily meltable alloy. COPYRIGHT: (C)2009,JPO&INPIT

Abstract:
The present invention provides a heat insulation covering for a spherical storage tank such as an LNG tank or the like for storing an extremely low temperature liquid. The covering is constructed by using elongated panel-like heat insulating panels. A plurality of slit parts having a U-shaped cross section are formed along the longitudinal direction of a foam-resin heat insulating panel formed in an elongated panel-like configuration. In the slit part, a heat insulating material is inserted. The material has a sufficient expandability under extremely low temperatures. The heat insulating panel can be deformed along the curvature of the surface of the spherical tank. The heat insulation covering of the spherical tank is formed of the heat insulating panels which have an elongated configuration. With such a structure, only a few kinds of heat insulating panels need be prepared, which is favorable in terms of cost.
