A recently granted patent (Publication Number: US11913606B2) discloses a large-scale hydrogen refueling station designed to efficiently facilitate the flow of hydrogen gas for refueling vehicles. The station comprises a supply storage with multiple vessels, compressor modules with local autonomous controllers, dispenser modules, and a hydrogen production system controlled by a central controller. The system allows for the simultaneous flow of hydrogen gas through three different paths, enabling efficient refueling from the supply storage to dispenser modules. The central controller manages the valves to control the flow of gas between the vessels, compressor modules, dispenser modules, and the hydrogen production system, ensuring a seamless refueling process.

Furthermore, the patent details a method for refueling vehicles at the large-scale refueling station, involving steps such as connecting the vehicle vessel to a dispenser module, initiating the refueling process, and controlling the flow of hydrogen gas through different paths. The method includes pressure consolidation of storage vessels, simultaneous refueling and consolidation processes using multiple compressor modules, and efficient transfer of gas between different storage units. The innovative approach outlined in the patent aims to optimize the refueling process, ensuring a smooth and effective experience for vehicles approaching the station. The system's design and method offer a comprehensive solution for large-scale hydrogen refueling, addressing various aspects such as pressure management, flow control, and efficient utilization of compressor modules to enhance the overall refueling process.
