Claim 0:
1. A large-scale hydrogen 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 autonomous 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,
wherein the local autonomous central controller facilitates control of valves and thereby the flow of hydrogen gas between the vessels of the supply storage, the compressor modules, the dispenser modules and/or the hydrogen production system, and
wherein the control of the valves enable the flow of hydrogen gas in three flow paths simultaneously, thereby enabling simultaneous flow of hydrogen gas from the vessels to a first and second of said dispenser modules, the plurality of flow paths comprising:
an inlet flow path between a first vessel of said plurality of vessels and a first compressor module of said plurality of compressor modules,
an outlet flow path between said first compressor module and said first dispenser module, and
a dispense flow path between a second vessel of said plurality of vessels and said second dispenser module;

wherein the valves are further controlled 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.
