SYSTEM OF UTILIZING CARBON DIOXIDE

A system of utilizing carbon dioxide comprises a carbon dioxide capturing device for capturing carbon dioxide, an electrochemical reaction device for producing synthetic gas by reducing the carbon dioxide captured by the carbon dioxide capturing device, a hydrogen carrier manufacturing device for manufacturing a hydrogen carrier material by using the synthetic gas produced by the electrochemical reaction device, a dehydrogenation device for producing hydrogen from the hydrogen carrier material manufactured by the hydrogen carrier manufacturing device, and a hydrogen utilization device for utilizing hydrogen produced by the dehydrogenation device, wherein the dehydrogenation device further produces carbon dioxide from the hydrogen carrier material and supplies the carbon dioxide to the carbon dioxide capturing device.
