1. A method of refueling a receiving vessel system with a hydrogen gas from a supply vessel system,
the receiving vessel system is fluidly connected to the supply vessel system via at least one hydrogen flow line,
the receiving vessel system comprising a plurality of receiving vessels and receiving vessel valves,
the supply vessel system comprising a plurality of supply vessels and supply vessel valves,
wherein the flow of hydrogen gas from the supply vessel system to the receiving vessel system is controlled by a refueling controller,
the method is characterized in that the refueling controller:
establishes information related to pressure from at least one of the plurality of supply vessels and from at least one of the plurality of receiving vessels,
based on the established information, determine a match between at least one supply vessel and at least one receiving vessel,
based on the match, controlling the status at least one supply vessel valve and at least one receiving vessel valve to allow flow between the matched supply vessel and receiving vessel so that the at least one of the plurality of receiving vessels are filled to its target pressure by flow of hydrogen gas directly from two or more of the plurality of supply vessels, and
wherein at least one receiving vessel is only filled to a reference fill and,
wherein the reference fill is 60-95% of the capacity of said receiving vessel.
