Title:
HYDROGEN REFUELING STATION AND SYSTEM, AND METHOD OF USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2023/165025
Kind Code:
A1
Abstract:
A system and a method for dispensing a liquefied fuel (e.g., hydrogen) are provided. The system (100) includes a cryotank (20) for storing a liquefied fuel (30), a first liquid pump (42) and a second liquid pump (44). The first pump (42) has a first maximum flow rate and pumps a first stream (11) of the liquefied fuel (30) having a first pressure. The second pump (44) has a second and lower maximum flow rate, and pumps a second stream (21) of the liquefied fuel (30) having a second and higher pressure. Each pump (42, 44) is connected with a heat exchanger (62, 64) to vaporize a stream (12, 22) of the liquefied fuel (30) to provide a respective vaporized substream (13, 23). Each pump (42, 44) is also connected with a mixer (72, 74) which combines the respective vaporized substream (13, 23) and a respective second substream (14, 24) of the liquefied fuel (30) to provide a respective gaseous fuel stream (32, 34). The gaseous fuel streams (32, 34) can be separately or jointly dispensed to one or more vehicles through a piping manifold (80) and at least one dispenser (90, 92). The system can refuel hydrogen to multiple fuel cell vehicles simultaneously, through multiple dispensers and multiple fluid circuits. The fluid circuit can provide various pressure capabilities. The fill rate and vehicle throughput of a refueling station can be significantly improved.
