Claim 14:
15. A method of refueling a vehicle vessel from a large-scale refueling station comprising a supply storage comprising a plurality of vessels, a plurality of compressor modules each comprising a local autonomous controller, three dispenser modules, a hydrogen production system comprising a hydrogen production system controller, and a local autonomous central controller disposed in communication with the local controllers,
wherein the supply storage, the plurality of compressor modules, the dispenser modules and the hydrogen production system are mutually connected to enable a flow of hydrogen gas therebetween, the method comprising the following steps:
connecting a first vehicle vessel to a first dispenser module,
starting the refueling from a user interface,
initiating a flow of hydrogen gas from a vessel of said supply storage via a dispense flow path during a first part of the refueling,
continuing the flow of hydrogen via an inlet flow path, compressor module, and an outlet flow path during a second part of the refueling, and
disconnecting the dispenser module from the vehicle vessel when a target pressure is reached,
wherein said initiating comprises activating the local autonomous controller of the compressor module associated with the first dispensing module to which the vehicle vessel is connected based on a local autonomous controller change status of one or more valves to facilitate said flow of hydrogen gas to said first dispenser module via said dispense flow path during the first part of the refueling and via said inlet flow path, compressor module and an outlet flow path during the second part of the refueling and, simultaneous with said second part of the refueling of said first vehicle vessel, a change status of one or more valves allows a flow of gas from a vessel of said supply storage via said dispense flow path to a second dispenser module fluidly connected to a second vehicle vessel;

wherein the method further comprises the steps of controlling the valves to establish
a first supply flow path between the hydrogen production system and the supply storage, and/or
a second supply flow path between the hydrogen production system and at least one of the plurality of compressor modules,

wherein said control of the valves facilitates flow of gas in the first supply flow path or in the second supply flow path simultaneously with flow of gas in at least one of the inlet flow path, the outlet flow path, a consolidation flow path or the dispense flow path.
