The present invention relates to an adsorbed natural gas system (1); which aims to store, fill and use natural gas for natural-gas-driven-systems in motor vehicles; and comprises at least one adsorbed natural gas storage (2) wherein the natural gas is stored, at least one natural gas vacuum cycle (2) which enables to discharge the natural gas from the adsorbed natural gas storage (2), at least one natural gas filling cycle (2) which enables to fill natural gas into the adsorbed natural gas storage (2), at least one natural gas usage cycle (5) which enables the natural gas to be delivered from the adsorbed natural gas storage (2) to the engine in order to be used, at least one water cycle (6) which enables to control temperature of the adsorbed natural gas storage (2) during use, at least one control unit (7) which controls the operations of the system via the information received from the sensors and controls the concerned valves.
