A system and method for dispensing liquefied fuel
A recently filed patent (Publication Number: US20230279995A1) describes a system for a hydrogen refueling station. The system includes a cryotank for storing liquefied hydrogen fuel, as well as two pumps with different flow rates and pressures. The first pump provides a lower pressure and higher flow rate stream of liquefied fuel, while the second pump provides a higher pressure and lower flow rate stream.
The system also includes heat exchangers and mixers to vaporize and combine substreams of the liquefied fuel, resulting in two gaseous fuel streams. These gaseous fuel streams are then delivered to at least one dispenser through a piping manifold. The dispenser is capable of dispensing either or both of the gaseous fuel streams into the on-board storage tank of a vehicle.
The patent also mentions that the system can have multiple sets of pump combinations, allowing for different pressure and flow capabilities. Additionally, the system can include multiple dispensers to refuel multiple vehicles simultaneously.
The hydrogen refueling station described in the patent includes similar components as the system, such as the cryotank, pumps, heat exchangers, mixers, piping manifold, and dispenser. The station is capable of delivering the gaseous fuel streams to the dispenser, which then dispenses the fuel into the on-board storage tank of a vehicle.
The patent also describes methods of using the system and the hydrogen refueling station. These methods involve initiating and completing the refueling process by dispensing the gaseous fuel streams into the on-board storage tank of a vehicle. The methods can also include adjusting the ratio of the gaseous fuel streams and refueling multiple vehicles in sequence.
Overall, this patent describes a system and a hydrogen refueling station that utilize pumps, heat exchangers, mixers, and dispensers to deliver gaseous fuel streams into the on-board storage tanks of vehicles. The system and station can accommodate different pressure and flow capabilities, as well as refuel multiple vehicles simultaneously.
