The present invention can improve the economical efficiency of a carbon dioxide capture and storage system by recovering low-temperature heat from an absorption heat pump in the process of operating the absorption heat pump using the exhaust heat of a fuel cell and high-temperature heat being generated from a heat recovery system. The carbon dioxide capture and storage system according to the present invention can be put to practical use earlier via the capacity increase of the carbon dioxide capture and storage system and the improvement of economical efficiency by operating the generation tower of the carbon dioxide capture and storage system needing a large amount of energy using thermal energy coming from the absorption heat pump. Thereby, the present invention can solve the problems of global warming and climate change by applying technologies for capturing carbon dioxide being discharged from a massive carbon dioxide emission source such as power plants, steel plants, cement plants and oil refineries, wherein carbon dioxide is emitted by the use of fossil fuels. Also, the technology of the carbon capture and storage system capable of stably using sustainable fossil fuels can be applied until economical new renewable energy is developed.
