A cryogenic dewar may include an inner tank and an outer tank. The cryogenic dewar may further include a plurality of trunnion mounts. A first four of the trunnion mounts may be coupled between a front half of the inner tank and a front half of the outer tank. A second four of the trunnion mounts may be coupled between a rear half of the inner tank and a rear half of the outer tank. The trunnion mount may be further strengthen with a plurality of pie-shaped reinforcing pads welded to each other and to an outer surface of the inner tank.

Systems and methods are provided for a combined defuel and priority panel for a fueling station. The defuel and priority panel is configured to defuel a compressed natural gas (CNG) vehicle and direct the defueled gas to fuel other CNG vehicles at the panel fueling and defueling site. The defuel and priority panel is also configured to store defueled gas in defuel storage tanks, which can then be used to later fuel CNG vehicles.

A mobile CO2 filling system selectively fills onsite CO2 storage and dispensing systems with CO2. The system includes a mobile platform; a tank holding liquid CO2 mounted on the mobile platform; a flexible dispensing hose couple to the tank and configured to be selectively coupled to the filling inlet of an onsite CO2 storage and dispensing system; a pump selectively coupled to the tank; and a controller for controlling the filling of an onsite CO2 storage and dispensing systems with CO2 from the tank, wherein the controller is selectively designated by the user to operate in at least one pump assisted filling state and at least one gravity feed filling state.

Fuel gas distribution method where residual fuel gas in a mobile fuel gas storage vessel being transported by a transport vehicle is transferred from the mobile fuel gas storage vessel to the transport vehicle for generating power. The fuel gas may be natural gas or hydrogen. The transport vehicle may be a fuel cell vehicle.

A tank configured to store a pressurized gas therein and carry a structural load between components of a vehicle.

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 system for the storage and transportation of high pressure compressed natural gas. The system includes a gas distribution manifold having an inlet and an outlet, wherein the inlet is configured to be connectable to a natural gas supply source, and a plurality of storage vessels in fluid communication with the distribution manifold between the inlet and the outlet. The system further includes at least one isolation valve operatively connected between the gas distribution manifold and the plurality of storage vessels, wherein the at least one the isolation valve is configured to control gas filling and discharging of the plurality of storage vessels.

The filling station according to the invention enables an automated refilling of a gas bottle by an end-user. This comprises an insertion device, which enables an end-user to insert an emptied gas bottle into the filling station. The filling station comprises a closing device for closing the filling station after the insertion of the gas bottle such that a removal of the gas bottle subsequent to the closing is not possible. The end-user may not remove the gas bottle in a closed state. Furthermore, the filling station comprises a filling device for an automated filling of an into the filling station inserted emptied gas bottle subsequent to the closing. A filling may thus only take place, if the filling station is closed and in consequence the gas bottle cannot be removed. There is a gas testing device for an automated gas leakage test after a refilling of an inserted gas bottle. With it, the tightness of a once again filled gas bottle is tested. There is a release device that releases an afore filled or full gas bottle only after a successful gas leakage test and thus enables a removal of a once again filled gas bottle. A removal of a gas bottled filled with gas respectively liquid gas is thus only possible, if the gas leakage test revealed that no gas escapes from the filled bottle. The invention further concerns a method for refilling.

A water-borne carrier for transporting liquefied natural gas (LNG) and liquefied nitrogen (LIN). A plurality of dual-purpose cryogenic storage tanks are arranged along a length of the ship. The plurality of dual-purpose cryogenic storage tanks may contain LNG or LIN. A LNG-only cryogenic storage tank may be arranged along the length of the ship. The LNG-only cryogenic storage tank contains only LNG.
