Abstract: An electrolytic synthesis system is equipped with an electrolysis device, a synthesis device, a gas adsorption type storage battery, and a control device. The gas adsorption type storage battery adsorbs, to electrodes thereof, carbon dioxide gas within the atmosphere during charging, and releases the carbon dioxide gas that was adsorbed to the electrodes, during discharging. When an adsorption amount of the carbon dioxide gas adsorbed to the electrodes exceeds a predetermined first threshold value, the control device controls a discharging switch and thereby initiates discharging of the gas adsorption type storage battery.
