description The present invention provides a continuous production method of hydrogen which is able to produce hydrogen, which is clean energy, simply and continuously without using ammonia as stated in BACKGROUND ART and which has a very high level of safety. The invention of the continuous production method of hydrogen includes a hydrogen production step comprising introducing mayenite (Ca 12 Al 14 O 33 ) and calcium hydroxide [Ca(OH) 2 ] into water and allowing them to react with water, thereby generating hydrogen and also forming katoite [Ca 3 Al 2 (OH) 12 ]; a regeneration step comprising baking the formed katoite to regenerate mayenite and calcium hydroxide; and a circulation step comprising returning the regenerated mayenite and calcium hydroxide into the hydrogen production step. It is preferable that a temperature of water in the hydrogen production step is from 50 to 100°C, and a molar ratio of mayenite to calcium hydroxide is 1/9. In addition, it is preferable that a baking temperature of katoite in the regeneration step is from 300 to 500°C.
