A gas supply marine vessel and a refueling facility are described. The gas supply marine vessel includes a hull with an upper deck having an elongated cargo cavity formed therein. Gas interface modules are disposed in the cavity and extend between hull sides, each module having a plurality of fuel vessel docking stations. A plurality of stacked fuel container assemblies are fluidically coupled to the docking stations. A gantry, is movable along the length of the cavity, straddles the cargo cavity between hull sides. An articulating crane is mounted on the gantry and it utilized to move fuel container assemblies to a fuel container depression formed in the deck of a floating refueling facility. The floating refueling facility includes a concave side to facilitate mooring adjacent a shoreline, the concave side forming angled extensions at corners of the deck with a linkspan extending from each of the angled extensions.

A system includes a processor configured to wirelessly instruct fuel dispensation initiation over a direct wireless connection between a vehicle and a refueling truck, responsive to a wireless request made by the refueling truck, the request including a valid token and a refueling truck MAC ID with which the wireless connection is established.

One or more indicators provide an indication of fueling status of a hydrogen powered vehicle. One or more sensors detect temperature and/or other characteristics of the fuel provided to the vehicle and provide an electrical signal to one or more of the indicators to permit an indication of fueling status. The indicators, which may be visual and/or audible, may be positioned on the fueling apparatus and on the vehicle in the vicinity of a fueling receptacle. The indicators may also be positioned elsewhere on the vehicle and may be separate from the vehicle such as on or around a fueling station and/or on separate computerized devices. Certain of the visual indicators may be positioned on a fueling hose and may include electrically energized paint and an illuminated sheath.
