SELF-SUPPLIED HYDROGEN TUBE TRAILER

The invention relates to a tube trailer comprising: a first hydrogen gas source comprising gaseous hydrogen, a second hydrogen gas source comprising gaseous hydrogen, a controller, an outlet connection, and a fuel cell. Wherein said first and said second hydrogen gas sources, are fluidly connectable to said outlet connection and to said fuel cell via a conduit system, thereby facilitating refueling a receiving vessel, when connected to said outlet connection, and energy production by said fuel cell, and wherein said fuel cell is electrically connectable to an electric load thereby facilitating supply of electric power to said electric load, when electrically connected to said fuel cell. Wherein said controller is configured to establish a flow of said gaseous hydrogen in said conduit system from said first hydrogen gas sources to said fuel cell when the pressure in said first hydrogen gas source is below a dispensing threshold pressure.
