Abstract:
PURPOSE: A tank for pressurized fluid is provided which comprises plural elementary tanks parallely connected to at least one manifold and a tank equipped with manifolds appropriate to separate any elementary tank, responding to declining internal pressure. CONSTITUTION: A tube(30) is so arranged ad to be parallel with each other in plural layered row, in other words, bundle-type array, all tubes have an identical diameter and wall thickness. For example, The tubes are composed of a metal such as a steel and a composite material such as an epoxy resin which is reinforced with a carbon fiber or 'kevlar'. A length and a number of the tube(20) is determined with an optimum method appropriate to accommodate a tank beneath a car structure. At both ends of each tube, each tube(20) is connected to a manifold(30) of which the elementary tube of the given tube row is formed to be connected with each other. An additional manifold(32,34) connects to each other at the both end of each tank, connected to a duct(36) connecting the tank(10) to an inlet for a usage and an outlet for discharging. Each end of the elementary tank(20) is welded or bolt jointed with an end(22a) of the elementary tank(20), connected to the manifold(30) by a connection unit(22) which would be welded or bolt jointed at the opposite end.
Abstract:
Die Erfindung offenbart ein System zum Speichern eines Energieträgerfluids, wie z.B. Wasserstoff, Methan, Methanol, CNG, usw., umfassend: a) mindestens einen mit dem Energieträgerfluid aufblasbaren Speicherbehälter, der eine flexible und fluiddichte Hülle umfasst; b) mindestens ein Stützelement für den Speicherbehälter, das eine Druckdifferenz zwischen einem Behälterinnendruck und einem auf den Speicherbehälter einwirkenden Aussendruck aufnimmt, vorzugsweise wenn der Behälterinnendruck grösser als der auf den Speicherbehälter einwirkende Aussendruck ist, und c) ein mit dem mindestens einen Stützelement assoziiertes Ballastelement, das eine eventuell vorhandene Auftriebskraft des Speicherbehälters in seinem umgebenden Medium zumindest teilweise aufnimmt; und/oder d) ein mit dem mindestens einen Stützelement assoziiertes Verankerungselement, die eine eventuell vorhandene Auftriebskraft des Speicherbehälters in seinem umgebenden Medium zumindest teilweise aufnimmt. Auf diese Weise ist es möglich, Energieträgerfluide vergleichsweise preiswert und ohne grossen Aufwand speichern zu können. Besonders dann, wenn der Aussendruck in etwa dem Druck entspricht, mit dem das Energieträgerfluid in den Speicherbehälter eingefüllt wird, kann eine vergleichsweise hohe Verdichtung mit einem sehr kleinen Aufwand erzielt werden. Derartige Verhältnisse liegen beispielsweise bei einer Anordnung des Energiespeichers unter Wasser oder in einem umgebenden Druckbehälter vor.

Abstract:
The present invention relates to a gas storage (110)for storing a gaseous medium. The gas storage (110) comprises a membrane (101) which is mounted to the gas storage (110) for at least partially enveloping a storage volume (Vi) of the gas storage (110) and wherein the membrane (101) is made of a flexible material such that the shape of the membrane (101) is adaptable to a filling level of gas in the storage volume (Vi). The membrane (101) comprises a reflection portion (102) for reflecting radar beams. The gas storage (110) further comprises a radar level measurement system for determining the filling level of gas in a storage volume (Vi) of the gas storage (110)by emitting radar beams in the direction to the membrane (101) and for detecting radar beams reflected by the reflection portion(102) of the membrane (101).
Abstract:
El almacenamiento amortiguado de gases es un sistema que permite almacenar cualquier tipo de gas en cualquier tipo de tanque a presión ó caverna de tal forma que la presión se mantiene constante tanto durante el llenado como durante el vaciado, consiguiéndose de este modo optimizar los rendimientos energéticos de los procesos de llenado y vaciado del tanque a presión ó caverna, e incrementándose de forma importante la energía almacenada por unidad de volumen.
Abstract:
Methods and systems for tagging carbon dioxide to be stored in a geologic formation are disclosed. In some embodiments, a method includes: providing a carbon dioxide tracer that is quantifiable and distinguishable versus non-anthropogenic produced carbon dioxide; providing carbon dioxide to be stored in the geologic formation; determining what portion of the carbon dioxide is anthropogenic produced carbon dioxide; and mixing a predetermined quantity of the carbon dioxide tracer with the carbon dioxide stored to develop a tagged quantity of carbon dioxide for storage in the geologic formation. In some embodiments, a system for tagging a stream of carbon dioxide includes a tagging module and a mixing module. Tagging module includes a carbon dioxide tracer that is quantifiable and distinguishable versus non-anthropogenic produced carbon dioxide. Mixing module includes mechanisms for containing and injecting the carbon dioxide tracer into a stream of carbon dioxide.
Abstract:
A fluid tight container for storage and transportation of high pressure compressed gas, the container (110) having a first connection (112) which serves as an inlet and outlet for gas to be stored in the container, a flexible impermeable membrane (111) dividing the container into a first portion (115) for gas and communicating with the first connection, and a second portion (116) for liquid, in which the second portion communicates with a second connection (114) for introducing or withdrawing liquid from the second portion. The invention facilitates the charging and discharging of the gas at a controlled pressure.
Abstract:
A deep ocean gas storage system for storing compressed gas, the system comprising an inflexible thin walled storage vessel anchored to the sea floor having an axis located in water substantially perpendicular to and on a sea floor below sea level, a gas intake for admitting and discharging compressed natural gas to and from the vessel; a water port for admitting and discharging water to the vessel using hydrostatic pressure to discharge compressed gas from the vessel at a substantially constant discharge pressure as the volume of the gas in the storage vessel decreases when water content of the vessel increases; a conduit fluidly connected with the water port oriented substantially parallel to the axis having a discharge opening above the level of sea water in the vessel; and a valve disposed at the gas intake to the vessel for controlling compressed gas admission and discharge.
Abstract:
A storage apparatus for storing a pressurised fluid comprises an outer vessel (2) and a plurality of separately sealed inner vessels (4). Means are provided for communication with the interiors of the inner vessels and of the outer vessel respectively (6,18,12). Also disclosed is a valve (12) for selectively allowing the passage of a fluid. The valve comprises a membrane (14) which is impermeable, within a predetermined temperature range, to the fluid to be stored. It also comprises heating means (16) for raising the temperature of the membrane above said temperature range, thereby allowing the fluid to diffuse through the membrane.
