Abstract:
A flat inner container (3), especially an internal tank for a road vehicle, which is surrounded by an outer container (1) and is used for receiving a cryogenic liquid, particularly a fuel. The inner container (3) comprises a combination of the following features: a longitudinally extending monolithic base (4) with a top wall (5) and a bottom wall (6) which are connected to also longitudinally extending sidewalls (7), and with at least two longitudinally extending, substantially straight webs (9) that connect the bottom wall (6) to the top wall (5) so as to form at least one longitudinally extending chamber (10) which is arranged between the webs, extends along the entire length of the base (4) as well as from the bottom wall (6) to the top wall (5), and has a predetermined width between the webs; and at least two caps (11) which tightly seal the two open ends of the base (4) at the periphery; the top wall and/or the bottom wall is/are provided with an arch relative to a planar reference top wall and/or reference bottom wall, the distance of the arch between the inner contour of the top wall and/or the bottom wall and the planar reference top wall and/or reference bottom wall amounting to less than 30 percent of the width of the chamber in the center between the webs.
Abstract:
These inventions related to systems and methods for producing, shipping, distributing, and storing hydrogen. In one embodiment, a hydrogen production and storage system includes a plurality of wind turbines for generating electrical power; a power distribution control system for distributing, and converting the electrical power from the wind turbines, a water desalination and/or purification unit which receives and purifies seawater, and an electrolyzer unit that receive electrical power from the power distribution system and purified water from the desalination units and thereby converts the water into hydrogen and oxygen. After its production, hydrogen is stored, transported, and distributed in accordance with various embodiments.
Abstract:
Composite pressurizable structures overwound with fibers or braided bundles of fibers are described. The pressurizable structures comprise one or more axial sections which themselves comprise both concave and convex surfaces. The shape characteristics are related to geodesic as well as to non-geodesic trajectories of the fibers. Axial sections of the pressurizable structures can be rotated, expanded, or bended with respect to their longitudinal axis. Such pressurizable structures may be used in pressure vessels, flexible pipelines, spring elements, robotic actuators, adaptive buildings among other uses. Manufacturing techniques facilitated by the present structures allow for the construction of very large structures.
Abstract:
A pressure vessel arranging and integrating a plurality of vessel structures each including a cylindrical liner opened at both ends and a fiber reinforced resin layer covering the outer periphery of the peripheral wall of the liner. Dome-shaped communicating members bulging outward are fixed across both respective ends of the liners of the vessel structures, thereby making the interiors of these liners communicate with each other and closing the open ends of these liners. This pressure vessel can be installed with no wasted space, and also allows an increase in capacity.

Abstract:
A storage tank containment system including a cubic-shaped tank having an outer shell having cylindrical walls for the efficient storage and transportation of large quantities of fluid, for example, liquid and compressed natural gas.
Abstract:
A cryogenic-capable high pressure container which combines the use of cryogenic-capable high pressure vessels and ultra-thin thermal barrier(s) having a thickness less than about 5 mm because of the reduced thermal requirements of the container from flexible usage, for maximizing storage space. Additional increase in storage capacity may be obtained by using conformable pressure vessels having box-shaped configurations for further maximizing storage space and capacity. Further efficiencies may be achieved by nesting high pressure vessels inside box-shaped lower pressure vessels to utilize for storage the interstitial spaces form between them.
Abstract:
A cryogenic propellant storage tank system and method are disclosed that thermally couple LO2 and LCH4 tanks together by using either a single tank compartmentalized by a common tank wall or two separate tanks that are coupled together with one or more thermal couplers having high thermal conductivity. Cryogenic cooling equipment may be located only in the LO2 tank while the LCH4 is cooled by the LO2 tank interface. Embodiments of the invention may employ both LO2 and LCH4 liquid acquisition devices (LADs) for low-gravity use. In further embodiments, only the LO2 LADs may be integrated with thermal cooling equipment.
Abstract:
A container for use as a storage device for a substance for operating a drive assembly of a motor vehicle is provided, in particular for a cryotank for condensed gases. At least one inner container receives the substance for operation. The inner container is held in at least one outer container, where at least parts of the inner container and/or the outer container are made of plastic, and these container parts have at least in part a coating or a metal inlay. The container is characterized by the fact that the outer side of the inner container has a full-surface metal or ceramic coating.
Abstract:
A method and an installation for alternating storage of CO2 and natural gas in a way that ensures minimal mixture of the gases, is described. CO2 and natural gas are alternately stored in a tank installation comprising a plurality of tanks connected in series, where CO2 is always filled and emptied through a first tank in the series of tanks, and where natural gas always is filled and emptied through a last tank in the series of tanks.
