To provide a hydrogen system capable of reducing the cost of producing hydrogen and stably producing hydrogen.SOLUTION: A hydrogen system of an embodiment comprises: a hydrogen production unit which produces hydrogen using power supplied from a plurality of power sources; a hydrogen storage unit which stores hydrogen produced by the hydrogen production unit; and a control unit which controls an operation of the hydrogen system so that a hydrogen generation speed at which the hydrogen production unit produces hydrogen per unit time holds a predetermined value. The control unit performs control so that the hydrogen production unit receives the supply of power preferentially from a power source which is determined to be able to supply power at a low price among the plurality of power sources.SELECTED DRAWING: Figure 1 【課題】水素を製造するコストの低減、および、安定的に水素の製造を実行可能な水素システムを提供する。【解決手段】実施形態は、複数の電源から供給される電力を用いて水素を製造する水素製造部と、水素製造部において製造された水素を貯蔵する水素貯蔵部とを備える水素システムであって、水素製造部において単位時間当たりに水素を製造する水素製造速度が予め定めた値を保持するように、当該水素システムの動作を制御する制御部を有し、制御部は、複数の電源のうち価格が低い電力を供給可能と判断した電源から優先的に前記水素製造部が電力の供給を受けるように制御を行う。【選択図】図１
