Provided are vacuum-insulated articles that comprise an evacuated space disposed between first and second walls and a reflective material disposed within the evacuated space. Also provided are methods of fabricating such articles.

The invention relates to a method for providing pressurized gas from a source of liquefied gas to a consumer (8), wherein vaporized gas is supplied from the source of liquefied gas (1) through a main input line (2) to a compressor arrangement (300) for pressurizing the vaporized gas, the compressor arrangement (300) comprising a plurality of compressor modules (3, 5, 31, 51), each compressor module being able to operate independently from any other compressor module of the compressor arrangement (300), one or more of the compressor modules (5, 51) of the compressor arrangement (300) can be bypassed, and wherein gas is conducted through only a part or all of the compressor modules depending on at least one of pressure level, temperature level, mass flow and composition of the gas to be provided to the consumer (8).

Disclosed is a BOG reliquefaction system. The BOG reliquefaction system includes: a compressor compressing BOG; a heat exchanger cooling the BOG compressed by the compressor through heat exchange using BOG not compressed by the compressor as a refrigerant; a pressure reducer disposed downstream of the heat exchanger and reducing a pressure of fluid cooled by the heat exchanger; and a second oil filter disposed downstream of the pressure reducer, wherein the compressor includes at least one oil-lubrication type cylinder and the second oil filter is a cryogenic oil filter.

Methods and apparatus are disclosed for a coupling nozzle for cryogenic fluid. An example nozzle includes a flow body defining a conduit. The flow body is configured to permit cryogenic fluid to flow through the conduit. The nozzle includes a mounting ring through which the flow body slidably extends and a bushing fixedly positioned adjacent the mounting ring. The bushing slidably receives the flow body in a keyed manner to prevent rotation of the flow body. The nozzle includes a flow control assembly at least partially disposed in the conduit of the flow body. The flow control assembly is configured to permit the cryogenic fluid to flow through the flow body in an open position and prevent the cryogenic fluid from flowing through the flow body in a closed position.

Composite tank apparatus and methods of making and using same. An array of flat-sided co-dependent cells with relatively thin skins made of metallic or non-metallic materials. Each cell has at least two flat wall panel portions connected by radiused sections arranged such that all of the flat wall panel portions are either in flush contact with each other or in flush contact with flat supporting panels of an enclosing structure or thermal insulating material lining an interior thereof. The cells are sealed with each other around a perimeter of at least one pair of matching lightening through-wall holes provided in adjacent pairs of the wall panel portions of the cells to resist relative movement and prevent leakage of fluid therefrom. The composite tank apparatus may include an enclosing structure, and optionally, one or more layers of thermally insulating material lining the interior surface or the exterior surface of the enclosing structure.

A pressure vessel assembly incudes a pressure vessel and a gas density gauge. The pressure vessel includes a vessel wall defining an interior cavity. The gas density gauge includes a parallel plate capacitor having a pair of plates. Opposing surfaces of the plates are separated by a distance across an open gap. A capacitance of the capacitor is related to a density of a gas within the open gap.

A storage tank includes a tank wall, a pressure regulator, a low-pressure coupling, and a fill coupling. The tank wall of the storage tank is configured to contain a stored fluid at an internal pressure within the tank wall, the tank wall including an outer layer, an inner layer, and a regulator mount. The pressure regulator of the storage tank is connected to the regulator mount and is configured to receive a flow rate of the stored fluid and reduce the stored fluid from the internal pressure to an output pressure. The flow rate of the stored fluid is provided, via the low pressure coupling and at the output pressure to an external system. The fill coupling extends through the tank wall and receives the stored fluid from a fluid source to be stored within the storage tank

A high-pressure tank unit capable of securing the sealing property of a sealing member in the neck of the high-pressure tank. The tank unit includes a high-pressure tank and a connecting member connected to the high-pressure tank. The connecting member has an annular sealing member disposed between a liner and an insert portion and adapted to seal a housing space. The high-pressure tank has a tubular body disposed between the liner and reinforcing layer in a position facing the sealing member so as to surround the outer peripheral surface of the liner, the tubular body adapted to restrict radial deformation of the inner peripheral surface of the neck. The longitudinal modulus of the material along the circumferential direction of the tubular body is higher than each of the longitudinal moduli of the materials along the circumferential direction of the liner and reinforcing layer.

A vehicle is equipped with a hydrogen tank that stores hydrogen, a fuel cell that generates electricity from the hydrogen in the hydrogen tank, a filling device 4 that fills a fuel cell vehicle with the hydrogen stored in the hydrogen tank, and a charger with which electricity generated by the fuel cell is charged to an electric vehicle. Using the vehicle, hydrogen and electricity are delivered to the home of a user.

A liquified air storage system can include a container assembly. The container assembly can be disposed on a base. The container assembly can have an interior portion and an exterior portion. The interior portion can include a reinforced concrete layer and a steel liner. The exterior portion can be disposed adjacent to the interior portion, the exterior portion including prestressed wire. A method of assembling a liquified air storage system can include assembling an interior portion of a container assembly. The interior portion can have a reinforced concrete layer and a steel liner. Next, an exterior portion of the container assembly can be assembled on the interior portion. The exterior portion can include a composite material and prestressed wires. The exterior portion can be covered with an insulation layer.
