A system to convert and dispense pressurized gas(es) of cryogenic liquids of gas(es), and systems and methods to efficiently convert liquid natural gas (LNG) to compressed natural gas (CNG) and low pressure natural gas (NG) and other cryogenic liquids of gas. The system requires one dedicated pressure vessel of horizontal and vertical elements at the dispensing location to convert, retain, store, and dispense multiple pressures of gas from a cryogenic liquid supply such as a non-dedicated high pressure cryogenic personal supply tank. The system efficiently modifies and controls parameters of volume, pressure, and temperature in conversion scale to retain all converted product under human control to dispense without process required waste for use in commercial, industrial, and in particular single family residential applications and service can be accomplished by pickup truck and trailer, where semi trucks, big rig trucks and process pollution are not welcome.

A system for storing fuel includes a support structure supporting at least one fuel tank a predetermined distance above ground. The fuel tank includes an inner tank configured to contain a gaseous fuel, an intermediate tank encompassing the inner tank and defining a first annular space therebetween, and an outer tank encompassing the intermediate tank an defining a second annular space therebetween. The first annular space is filled with a shock-absorbing resin for absorbing structural stresses, while the second annular space is filled with an insulating material providing for fire and ballistic resistance. The intermediate tank is connected to the support structure and to at least one adjacent fuel tank, and prevents the transfer of load to the inner tank.

A method is provided for producing a tank, in particular a motor vehicle tank, for storing a fuel in a low-temperature state. The tank has an inner tank receiving the fuel, an outer skin surrounding the inner tank and an insulating layer arranged between the inner tank and the outer skin. The method i) introduces fuel into the inner tank, a temperature of 30 C. to 120 C., preferably of 70 C. to 85 C., being obtained by the fuel in the inner tank, and ii) generates negative pressure in an insulating layer arranged between the inner tank and the outer skin.

A storage and/or transport container for a cryogenic liquefied gas, the container having a double wall which is formed by an outer container and an inner container, the outer container surrounding the inner container, and the outer container having a cylindrical jacket-like metal wall region which, at mutually opposite ends, i.e., at a first end and a second end, transitions into domed metal wall regions, the wall thickness of the cylindrical jacket-like metal wall region increasing in the direction of the first and second end starting from a central portion which lies centrally between the first and second end. In the central portion, a reinforcement layer is fastened to the cylindrical jacket-like metal wall region and has a fiber-reinforced plastic. The invention also relates to a method for storing and/or for transporting a cryogenic liquefied gas, in which a storage and/or transport container is used.

A storage system is provided that includes a primary container, a first insulation layer, a secondary container, a secondary bottom, and a second insulation layer. The primary container has a primary bottom. The first insulation layer is disposed below the primary bottom. The secondary bottom is disposed below the first insulation layer and the secondary container. The secondary bottom has an expansion joint configured to permit the secondary bottom to expand and/or contract independently from the secondary container. The second insulation layer is disposed below the secondary bottom. In the event of LNG leaking from the primary container, the second insulation layer is protected from LNG contact by the secondary bottom. The carbon steel liner located on the outside face of the concrete wall remains vapor tight and liquid tight in the event of any amount of LNG leaking from the primary container.

This invention describes a novel design and construction method for a Collapsible Cryogenic Storage Vessel that can be used for storing cryogenic liquids. The vessel provides the ability to be packed for transport in a compact state and erected at the point of use. The vessel can be used multiple times. The vessel's volume can also be adjusted during use to minimize or eliminate head space in the vessel.

This invention relate to a tank, for transport and/or storage of cryogenic gases where the tanks insulation (1) are on the inside of the tank. The tanks insulation (1) has a leak proof layer (2) made of carbon fiber, fiberglass, plastic, metal or similar leak proof material.

A pressure vessel apparatus for cryogenic capable storage of hydrogen or other cryogenic gases at high pressure includes an insert with a parallel inlet duct, a perpendicular inlet duct connected to the parallel inlet. The perpendicular inlet duct and the parallel inlet duct connect the interior cavity with the external components. The insert also includes a parallel outlet duct and a perpendicular outlet duct connected to the parallel outlet duct. The perpendicular outlet duct and the parallel outlet duct connect the interior cavity with the external components.

A storage tank containing a fluid, the liquefaction temperature of which is lower than 50 C. under atmospheric pressure and having a cylindrical shape around an axis of revolution, the storage tank includes at least one thermal insulation barrier covered with a sealed and corrugated membrane which is made of a plurality of corrugations. These corrugations delimit a space between the corrugations and at least one thermal insulation barrier. The storage tank includes at least one system injecting gas into the space, the gas injection system including at least one circular pipe spreading around the axis of revolution of the storage tank and a nozzle linked to the circular pipe.

A cryogenic fluid storage unit comprises: an internal reservoir, internally delimiting a storage volume for storing the cryogenic fluid, and an external reservoir inside which the internal reservoir is arranged. An intermediate space separates the internal reservoir from the external reservoir. A thermal insulation is interposed between the internal reservoir and the external reservoir. A a getter is received in a volume in fluidic communication with the intermediate space, and the external reservoir has an opening for extracting the getter, and a removable cover closes the opening.
