Advanced cascade filling of receiving vessels

A refueling system configured for refueling of a receiving vessel system comprising a plurality of receiving vessels, a temporary refueling system comprising a plurality of supply vessels,

• wherein the receiving vessel system is fluidly connected to the supply vessel system via at least one hydrogen gas gaseous connection,
• wherein a refueling controller is configured to control the flow of hydrogen gas from the supply vessel system to the receiving vessel system, based on information established related to pressure inside at least one of the plurality of supply vessels,
• wherein the refueling controller, based on the received pressure information, is configured to determine a pressure match between at least one supply vessel and at least one receiving vessel, and based on the match the refueling controller is configured for controlling the status at least one supply vessel valve to allow flow of hydrogen gas from the supply vessel to the matched receiving vessel,
• wherein the matched receiving vessel is only filled to a reference fill, wherein the reference fill is 60-95% of the capacity of said matched receiving vessel,
• wherein the plurality of supply vessels is part of a MEGC trailer for transportation and temporary storage of a pressurized gaseous fluid, wherein the MEGC trailer comprising:
• said supply vessels, wherein said supply vessels comprise at least two gas banks, wherein each of said two gas banks comprises at least one gas section, wherein said at least one gas section comprises at least one gas vessel, wherein said at least one gas vessels is configured for temporary storage of said pressurized gaseous fluid;
• a plurality of section valves, wherein each gas section is associated with one of said plurality of section valves which is configured for controlling flow of said pressurized gaseous fluid to and from said gas section;
• a fluid conduit system arranged to fluidly couple, through said section valves, gas sections within each of said at least two gas banks, wherein said fluid conduit system comprises a first coupling valve and a second coupling valve;
• said first coupling valve is configured for establishing a fluid connection between a first of the at least two gas banks and a first outlet connection and
• said second coupling valve is configured for establishing a fluid connection between a second of the at least two gas banks and a second outlet connection,
• wherein said first and second outlet connections are both configured for connecting said fluid conduit system to an external facility and thereby facilitate two-way gaseous fluid communication between the MEGC trailer and the external facility, and
• wherein the fluid conduit system furthermore comprises a first and a second bank valve between which an additional gas section is connected to the fluid conduit system via an additional section valve,
• wherein said first and second bank valves and said additional section valve are controllable so as to change the volume of at least one of the at least two gas banks with the volume of said additional gas section.
