The present invention relates to a hydrogen charging system, and more specifically, to a hydrogen charging system capable of reusing remaining hydrogen after charging, which collects remaining hydrogen in a dispenser after charging to supply the same to a storage tank without discharge. The hydrogen charging system according to the present invention comprises: a first conduit tube placed to introduce hydrogen from a gas supply source into the storage tank; a second conduit tube placed to introduce the hydrogen in the storage tank into a fuel cell car for charging; a dispenser having a charging conduit tube connected to communicate with the second conduit tube so that the hydrogen in the second conduit tube is introduced and a first valve for opening or closing the charging conduit tube for the second conduit tube; and a retention having a first vent line connecting the charging conduit tube and the first conduit tube to make them communicate with each other, so that the hydrogen remaining in the charging conduit tube closed by the first valve is introduced into the storage tank. 본 발명은 수소충전 시스템에 관한 것으로, 좀 더 구체적으로는 충전 후 디스펜서에 잔류하는 수소를 배출없이 수집해서 저장탱크에 충전시키는 충전 후 잔류 수소의 재이용이 가능한 수소충전 시스템에 관한 것으로, 가스공급원의 수소가 저장탱크에 유입되도록 배관된 제1도관; 연료 전지 자동차의 충전을 위해서 상기 저장탱크의 수소가 유입되도록 배관된 제2도관; 상기 제2도관의 수소가 유입되도록 제2도관과 연통하게 연결된 충전도관과, 상기 제2도관에 대해 충전도관을 개폐하는 제1밸브가 구성된 디스펜서; 상기 제1밸브에 의해 폐쇄된 충전도관에 잔류하는 수소가 저장탱크에 유입되도록, 충전도관과 제1도관을 연통하게 연결하는 제1벤트라인이 구성된 리텐션; 을 포함하는 것이다.
