Abstract:

Abstract:
A hydropneumatic filament-wound pressure vessel is disclosed. The vessel has first and second cup-shaped tank liners having circular open mouths which are provided with a seal and diaphragm assembly. The seal assembly includes a pocket formed by an inner wall and shelf associated with the first liner and a ledge associated with the second liner. The shelf, ledge and cylindrical wall cooperate with an inner surface of the second liner to provide an O-ring pocket. An O-ring is provided in the pocket and the O-ring defines the periphery of a flexible diaphragm which divides the interior of the liners into separate pressure chambers. A continuous filament is wound over the surface of the liners in an isotensoid pattern. Each liner has a geodesic dome surface extending between a diameter of the liner and a polar opening. The dome surface is defined by oppositely curving surfaces of revolution of a meridia joined by an inflection point. The first surface of revolution curves from the liner diameter to a first point just unto but not at said inflection point. The second surface of revolution curves from the polar opening to a second point just unto but not at said inflection point in a direction opposite the curvature of the first surface of revolution. The first and second surfaces are joined, and the inflection point is traversed by a straight line third surface of revolution closely approximating geodesic curvature through the inflection point.

Die Erfindung betrifft ein Verfahren zur Herstellung eines Druckluftbehälters in Kraftfahrzeugen. Es ist Aufgabe der Erfindung, die Herstellung eines Druckluftbehälters technisch und wirtschaftlich zu optimieren. Diese Aufgabe wird erfindungsgemäß zunächst durch das Herstellen zweier in etwa gleichgroßer Behälterhälften (2, 3) nach einem Umformverfahren gelöst, wobei öffnungsseitig beider Behälterhälften (2, 3) umfangsseitig umlaufende, etwa rechtwinklig hiervon abragende Stegränder (6, 7) gebildet sind, welche in einem nachfolgenden Arbeitsschritt durch nichtthermisches Fügen und unter zusätzlicher Verwendung eines Dichtmittels (8) zu einer gemeinsam gebildeten, umfangsmäßig umlaufenden Falzverbindung (4) umgeformt werden, durch diese beide Behälterhälften (2, 3) abdichtend miteinander verbunden sind.

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:
Systems and methods for storing energy in gaseous form in submerged thin-wailed tanks (1, 7, 61, 82, 63, 67, 101) are secured to the ocean or lake floor but are open to the water at the tank bottoms (1a, 64) and are configured to be filled with gas while submerged. A conduit (2, 2a, 11) operatively connected to the tanks (1, 7, 61, 62, 63, 67, 101) provides flow from a surface source of an energy-containing gas to the tank interiors (1d, 101 a). Surface or subsurface pumping apparatus (3, 37, 42, 46, 48, 53) which may include piston-less pressure cylinders (37) or have leveraged pistons (48, 53) provide a preselected flow rate of the energy-containing gas into the tank interiors (1d, 101 a) against a back pressure essentially equal to the static pressure of the body of water at the location of the tank (1, 7, 61, 62, 63, 67, 101) to displace an equivalent volume of water through the open bottom (1 a, 64). The conduit (2, 2a, 11) can be configured to allow heat transfer to vaporize liquefied gas prior to storage. Hydrogen gas can be generated and stored within the tank (1, 7, 61, 62, 63, 67, 101) using Aluminum activated with Galinstan.

The tanks (1) have an outer cylindrical shell (100) consisting of at least one metal tube (101) of the type used for gas and oil pipelines, having an outer diameter larger than 32" (813 mm), and a ratio of the length to the outer diameter thereof that is greater than 8.
