NOVELTY - The system has a set of similar spherical storage elements (20) arranged in a receiving space (14) and comprising a wall that encloses an inner space fillable with gaseous fuel. A pressure regulating valve is arranged in the wall of the receiving space for opening and closing a fluid connection between the inner space and the outer space surrounding the storage element. The pressure regulating valve produces an outflow of the gaseous fuel from the storage element, if the external pressure acting on the receiving space is less than the preset maximum external pressure.    USE - Radio frequency identification (RFID) integrated system for supplying gaseous fuel e.g. hydrogen, hydrocarbon comprising one to five carbon atoms (all claimed), and compressed natural gas such as methane, ethane and ethylene, to an internal combustion engine or a fuel cell of a mobile device e.g. motor vehicle such as passenger car and lorry. Can also be used for stationary facilities.    ADVANTAGE - The pressure regulating valve produces an outflow of the gaseous fuel from the storage element, if the external pressure acting on the receiving space is less than the preset maximum external pressure, so that the storage element can be made empty with small pressure difference, and the need for a high pressure valve for filling fuel in the storage elements is eliminated, thus preventing leakage of residual gaseous fuel from the storage element, and enabling a safe operation of the mobile device. The design of the system eliminates the need for mechanical connections such as inlet and outlet, between the receiving spaces. The receiving space has an arbitrary form, so that the utilization of the space in the mobile device can be optimized for storing the fuel.    DETAILED DESCRIPTION - The wall of the storage elements is made of fiber reinforced plastic material or metallic material such as steel.
