摘要： 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.

摘要： 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.
