This invention provides gas supply and dispensing system and method of operating the same, comprising first on-stream vessel and first standby vessel, wherein the system is used to dispense gas at a preset gas flow rate; sensors in communication with a controller to sense a predefined endpoint of the first on-stream vessel thereby causing the controller to initiate auto-crossing from the first on-stream vessel to the first standby vessel in the array having gas therein, for subsequent dispensing of gas from the first standby vessel; wherein the controller after sensing the predefined endpoint initiates flow of gas from the first standby vessel, the first standby vessel thereby becoming the second on-stream vessel dispensing gas concurrently with the first on-stream vessel for a period prior to terminating the flow of gas from the first on-stream vessel.

The hydrogen storage device may include a plurality of hydrogen tanks and a plurality of supply pipes corresponding to each of the plurality of hydrogen tanks, each of the plurality of supply pipes connecting the hydrogen tank and a supply destination to which hydrogen in the hydrogen tank is supplied, a plurality of solenoid valves provided in each of the plurality of supply pipes, and a control device capable of executing a hydrogen supply operation of supplying hydrogen to the supply destination by controlling the operation of the plurality of solenoid valves. In the hydrogen supply operation, the control device sets only the first solenoid valve out of the plurality of solenoid valves to the open state, sets the solenoid valve other than the first solenoid valve to the closed state, and changes the solenoid valve set as the first solenoid valve when the predetermined condition is satisfied.
