An apparatus includes a high-pressure tank, a controller, a valve, controlled by the controller, and a heater.

The invention relates to a method for refuelling a vehicle (60) or an autonomous vehicle (60). At least one hydrogen tank (10) accommodating gaseous hydrogen is fitted in the vehicle (60). The method comprises the following method steps: The vehicle (60) drives into a refuelling area (24). A refuelling operation (28; 78, 80, 82) is performed on the vehicle (60). Then, the temperature of the contents of the at least hydrogen tank (10) is checked (30). If a temperature (74) of the tank contents of the at least one hydrogen tank (10) exceeds a temperature limit value (32), the vehicle (60) is transferred to a cooling down area (36). There, the tank temperature (44) is checked a second time following a cooling down phase. The tank pressure is checked (48) if the tank temperature (74) lies below a temperature limit value. If the tank pressure (76) in the at least one hydrogen tank (10) is below a tank pressure limit value, the vehicle (60) is transferred to the refuelling area (24) to continue refuelling; if the tank pressure (76) is in the tank pressure limit range, refuelling is halted (52).

An insulation arrangement for an ocean-going ship comprising a modular arrangement of panels, each panel comprising a first cold layer and an opposing ambient layer and a volume therebetween arranged in use to be evacuated to create a vacuum.

A device for controlling a charging of a hydrogen tank for a vehicle, may efficiently perform a charging of a hydrogen tank regardless of a hydrogen charging protocol for each charging station configured to supply hydrogen to the hydrogen tank by directly controlling a hydrogen charging speed of the hydrogen tank in a vehicle upon charging the hydrogen tank mounted in the vehicle.

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.

The present invention relates to an aquarium pressurized gas vessel for supplying an aquarium (12) with CO2 gas generated in the aquarium pressurized gas vessel (10), wherein the aquarium pressurized gas vessel (10) comprises: a receiving vessel (14) for receiving a nutrient substrate and a reactant interacting with the nutrient substrate such that the nutrient substrate and the reactant react with each other to generate CO2 gas; a closing device (16) for closing the receiving vessel (14) in a pressure-tight manner; a gas outflow device (18) for extracting CO2 gas from the aquarium pressurized gas vessel (10) for the aquarium (12), wherein the CO2 gas has a gassing pressure (p_B) when flowing into the gas outflow device (18); a gas vessel pressure regulator (20) for adjusting a gas vessel pressure (p_G) which substantially corresponds to the gassing pressure (p_B).

Further, the present invention relates to a CO2 gassing system (28) comprising the aforementioned aquarium pressurized gas vessel (10).

The present disclosure provides systems and methods for refilling fluid containers. A fluid container may include a bottle and a valve assembly. The valve assembly may include two valves and be configured to engage with the bottle and a filling head or dispensing head. A system is configured to provide pressurized fluid to the refillable container, monitor filling, determine when to stop filling, and determine how much fluid was provided. The valve assembly may include a float mechanism coupled to one of the valves of the valve assembly to ensure fluid flow is stopped when the fluid container is full. The fluid, which can include carbon dioxide, is stored in a storage tank. A flow system provides the fluid to a filling head, which engages with the fluid container. The flow system includes a transfer pump, valves, and sensors configured to provide the fluid to the filling head.

To enable a hydrogen tank to be efficiently filled with hydrogen even when the hydrogen tank has a large capacity, hydrogen filling at the nozzle flow is prohibited when the nozzle flow of a nozzle is larger than the receptacle flow of a receptacle or when the receptacle flow is unknown under the condition that the nozzle and the receptacle can be connected to each other.

According to aspects, hydrogen fueling systems and methods are provided, including vehicle-to-vehicle communication techniques, hydrogen cooling techniques and/or hydrogen dispenser control techniques that facilitate improving aspects of a hydrogen fueling station.

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.
