Industrial Application of Carbon Recycling Energy System Technology Driven by Nuclear Power

Abstract

Industrial application of carbon recycling energy system technology driven by nuclear power as low-carbon new energy systems was discussed in this study. For establishment of nuclear power contribution on low-carbon energy system in future, energy storage and energy carrier technologies for nuclear power are required. Chemical energy storage would be an effective candidate for energy carrier. From the stand point of exergy, that is thermal energy quality, carbon media is higher quality than hydrogen. Carbon dioxide (CO2) decompositions into carbon monoxide (CO) is candidate for the carbon energy carrier. Carbon recycling energy system driven by a nuclear power has potential for new energy storage and carrier technologies. A new energy system of Active Carbon Recycle Energy System (ACRES) using CO as energy carrier driven by a high temperature gas cooled reactor (HTGR) was proposed for reduction of carbon dioxide emission and establishment of carbon supply security of a country. The feasibility of an ironmaking system based on ACRES (iACRES) driven by HTGR was discussed as an example of nuclear industrial application by process numerical analysis. It was expected that ACRES was capable to be a carbon recycling energy system technology driven by nuclear power for industrial sector as a low-carbon energy system methodology.
