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.

A system and a method with boil-off management for liquefied fuel storage are provided. The system includes a cryotank for storing a liquefied fuel, a pump for providing and compressing a first stream of the liquefied fuel, a heat exchanger for provide cooling duty to the first stream of the liquefied fuel, and an expansion valve for expanding the first stream of the liquefied fuel after the heat exchanger into a multiphase stream comprising a liquid phase and a gas phase. The multiphase stream has a temperature lower than an initial temperature of the first stream from the cryotank. The system further comprises a liquid-vapor splitter for separating the liquid phase and gas phase in the multiphase stream. The liquid phase is returned into the cryotank.

A vessel for the transport of liquefied gas has a hull, a cargo storage tank arranged in the hull for storing liquefied gas and an engine to propel the ship. A compressor has a compressor inlet connected to a vapour space of the at least one cargo storage tank for receiving boil-off gas at a first pressure and a compressor outlet for supplying pressurized boil-off gas to the at least one engine at a second pressure exceeding the first pressure. A boil-off gas recovery system is provided for recovery of boil off gas. The boil-off gas recovery system has a cooling section with a cooling section inlet connected to the compressor outlet to recondense at least part of the pressurized boil-off gas and a boil-off gas storage tank having a boil-off gas storage tank inlet connected to the cooling section outlet for storing the recondensed pressurized boil-off gas.

A system such as a hydrogen refueling station and a method are provided. The system includes a cryotank for storing a liquefied fuel having liquid and vapor phases, a pump for providing a first stream of the liquefied fuel in the liquid phase from the cryotank, a heat exchanger for converting at least a portion of the first stream to a gaseous fuel, a dispenser for dispensing at least a portion of the gaseous fuel to a receiving fuel tank, a refrigeration unit integrated with the heat exchanger, and a backup power unit. The refrigeration unit and the heat exchanger exchange heat with each other, and the refrigeration unit provides cooling capacity to a facility of environment where cooling is needed. The backup power unit generate electric power by using a second stream of the liquefied fuel in the vapor phase or in the liquid phase or both.

Method for filling a storage vessel with liquefied gas by means of a tank of liquefied gas, the method comprising a step of transferring liquefied gas from the tank into the storage vessel by means of a pressure differential, wherein the storage vessel prior to the transfer step has an internal pressure higher than the internal pressure of the tank, the method comprising, prior to the transfer step, a step of placing the tank and the storage vessel in fluidic communication in order to ensure a drop in the pressure in the storage vessel to the benefit of the tank and a step of increasing the pressure in the tank using a pressurizing device.

The present disclosure generally relates to a multiple receptacle fuel filling and storage system in a vehicle and/or powertrain, and a method of using the same.

A method for transferring cryogenic fluid from a storage tank (2; 12; 16) to a receiver (6; 8; 10; 14; 16; 18) like a receiving tank or to an application device, according to the invention comprises the steps of: a—pumping cryogenic liquid from the storage tank (2; 12; 16), b—vaporising at least partially the pumped cryogenic liquid, c—pressurising the storage tank (2; 12; 16) with the vaporised cryogenic liquid, and d—transferring cryogenic fluid to the receiver (6; 8; 10; 14; 16; 18) with cryogenic fluid from the storage tank (2; 12; 16) through a feed line (4) between the storage tank (2; 12; 16) and the receiver (6; 8; 10; 14; 16; 18).
