The present invention relates to a method and a system for supplying liquefied gas source tank (110) to a liquefied gas consumer tank (200) and/or liquefied gas consumer, wherein the liquefied gas is supplied via a transfer line (130, 140, 210) to the liquefied gas consumer tank (200) and/or the liquefied gas consumer, and wherein after having supplied liquefied gas to the liquefied gas consumer tank (200) and/or liquefied gas consumer, residual liquefied gas remaining in at least a part of the transfer line (130, 140, 210) is drained into a liquefied gas holding tank (120) and a pressurized gas is then fed into the liquefied gas holding tank (120) in order to return at least a part of the residual liquefied gas in the holding tank via a return line (160) back into the liquefied gas source tank (110).

A fuel transfer station may provide for the refilling of fuel canisters providing fuel to combustion powered equipment. The fuel transfer station may include a base, a frame coupled to the base, a first connection port and a second connection port provided in the base, and fluid flow lines connecting the first connection port and the second connection port. A supply tank may be supported by the frame and detachably connected to the first connection port. A fuel canister to be refilled may be detachably connected to the second connection port. Fuel contained in the supply tank may be selectively supplied to the fuel canister through the fluid flow lines in response to a pressure gradient drawing the fuel into the fuel canister.

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.

A multi-vessel fluid storage and delivery system is disclosed which is particularly useful in systems having internal combustion engines which use gaseous fuels. The system can deliver gaseous fluids at higher flow rates than that which can be reliably achieved by vapor pressure building circuits alone, and that keeps pressure inside the storage vessel lower so that it reduces fueling time and allows for quick starts thereafter. The system is designed to store gaseous fluid in liquefied form in a plurality of storage vessels including a primary storage vessel fluidly connected to a pump apparatus and one or more server vessels which together with a control system efficiently stores a liquefied gaseous fluid and quickly delivers the fluid as a gas to an end user even when high flow rates are required. The system controls operation of the pump apparatus as a function of the measured fluid pressure, and controls the fluid pressure in a supply line according to predetermined pressure values based upon predetermined system operating conditions.

A system delivers carbon dioxide to a sequestration facility which may have photosynthetic organisms, such as crops, plants, and trees. The system has a containment structure which houses a volume of liquid or solid carbon dioxide (dry ice). The containment structure has a containment structure inlet and a containment structure outlet. A gas source provides a fluid to the containment structure through the containment structure inlet. Upon entry into the containment structure, the gas or a saturated liquid encounters the solid or liquid carbon dioxide causing sublimation or evaporation, resulting in the formation of carbon dioxide gas or liquid which flows out of the containment structure through the containment structure outlet. The gas entering the containment structure may also have subcooled CO2 liquid or solid (snow), which replenishes the solid or liquid within the containment structure. To supplement evaporation or sublimation of the subcooled liquid or solid, heating means are used. A distribution line connected to the containment structure outlet delivers carbon dioxide gas or liquid which is flashed to gas upon release by CO2 emitters to the photosynthetic organisms.

A storage system for temporary storage of a gas comprising a storage vessel configured to store a pressurized gas or liquid; at least one of a compressor configured to pressurize the gas and provide the pressurized fluid or a liquefaction apparatus operable to liquefy the gas to provide the liquid; and piping associated with one or more valves, wherein the piping and the associated one or more valves are configured to provide: (a) in a first configuration, inflow of the gas into the compressor or the liquefaction apparatus, wherein the compressor is configured to pressurize the inflowing gas to provide the pressurized fluid or wherein the liquefaction apparatus is configured to liquefy the inflowing gas to provide the liquid, and introduce the pressurized gas or the liquid into the temporary storage vessel; and (b) in a second configuration, outflow of the pressurized gas or liquid from the temporary storage vessel.

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.

An emergency release system includes a first shut-off valve unit which is land-based; and a second shut-off valve unit which is provided for a marine vessel and separably connected to the first shut-off valve unit, and the first shut-off valve unit is provided with a reservoir container which receives liquid air generated in the first shut-off valve unit and dropped, in a state in which the second shut-off valve unit is separated from the first shut-off valve unit, and the system includes a container support mechanism which is capable of retaining the reservoir container at a retracted position in a state in which the first and second shut-off valve units are connected to each other, the container support mechanism being configured to automatically shift the reservoir container to a reserving position, in a state in which the first and second shut-off valve units are separated from each other.

A fluid-distribution assembly has controllable components. The fluid-distribution assembly also has a vehicle-fuelling connection configured to be selectively connectable to a first compressed-natural-gas tank of a first compressed-natural-gas-powered vehicle. The fluid-distribution assembly also has a fuel-storage connection configured to be selectively connectable to a fuel storage assembly. The fluid-distribution assembly is configured to be electrically connected to a controller assembly. The controller assembly is configured to monitor and control operations of the controllable components of the fluid-distribution assembly. The controllable components of the fluid-distribution assembly are configured to selectively distribute, under control by way of the controller assembly, a fluid flow of a compressed natural gas between the first compressed-natural-gas tank and the fuel storage assembly.
