Hydrogen supply system

A hydrogen supply system comprising:

• a plurality of hydrogen tanks that is attachable and detachable;
• a hydrogen consumption device that consumes hydrogen of the hydrogen tanks;
• and
• a control device, wherein:
• the hydrogen consumption device includes an attaching-detaching mechanism including a plurality of motors that controls attaching and detaching of the hydrogen tanks with respect to the hydrogen consumption device, the motors corresponding to the attaching and detaching of the respective hydrogen tanks;
• and
• the control device disposes, based on a temperature of each of the motors, a hydrogen tank of the hydrogen tanks to a hydrogen supply start position at which the hydrogen tank and the hydrogen consumption device are connected in a state in which the hydrogen tank is allowed to supply hydrogen to the hydrogen consumption device, or disposes the hydrogen tank to a hydrogen supply standby position at which the hydrogen tank and the hydrogen consumption device are not connected in the state in which the hydrogen tank is allowed to supply the hydrogen to the hydrogen consumption device and the hydrogen tank stands by for supply of the hydrogen.
