A hydrogen storage system may include: a storage vessel storing liquid hydrogen; a supply line connected to the storage vessel and connected to a fuel cell system, the supply line supplying gaseous hydrogen from the storage vessel to the fuel cell system; installed in the supply line and connected to the fuel cell system A compressor for compressing gaseous hydrogen; a bypass line connecting a supply line and a storage vessel and allowing gaseous hydrogen to flow from the supply line to the storage vessel; a control valve installed in the bypass line and selectively regulating the bypass flow of gaseous hydrogen; set an orifice in the bypass line; and a controller configured to control a control valve that precisely adjusts the supply pressure of the storage vessel and the amount of hydrogen supplied to the fuel cell system based on the operating conditions of the fuel cell. |
