Abstract: A method of refueling a receiving vessel system with a gas from a supply vessel system, where the receiving vessel system is connected to the supply vessel system via a flow line, the receiving vessel system comprising including a plurality of receiving vessels and the supply vessel system having a plurality of supply vessels, where the flow of gas from the supply vessel system to the receiving vessel system is controlled by a refueling controller based on information related to pressure from the plurality of supply vessels and from the plurality of receiving vessels, and, on the received information, a match between a supply vessel and a receiving vessel is determined and 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.

Abstract: The invention relates to a MEGC trailer for transportation and temporary storage of a pressurized gaseous fluid, the MEGC trailer comprising: two gas banks each comprising one or more gas sections and a fluid conduit system. The fluid conduit system comprises a first and a second bank valve between which an additional gas section is connected to the fluid conduit system. Wherein the first and second bank valves are controllable so that the volume of at least one of the two gas banks can be changed with the volume of the additional gas section.

Abstract: The invention relates to a hydrogen supervisory control and data acquisition system for monitoring a plurality of batches of hydrogen, the hydrogen supervisory control and data acquisition system comprising: a hydrogen production facility client, associated with a hydrogen production facility, a hydrogen customer client, associated with an entity receiving at least a subset of the plurality of batches of hydrogen and a central computer system. The central computer system is configured to establish a lifecycle data package of the plurality of batches of hydrogen. The lifecycle data package includes information associated with the production of the plurality of batches of hydrogen. The central computer system is configured to provide at least part of the lifecycle data package, to said hydrogen customer client.
