Outline of Final Research Achievements

This study proposes an Active Carbon Recycling Energy System (ACRES) to realize a carbon-neutral industry, and has successfully developed a stackable Metal Supported Solid Oxide Electrolysis Cell (MS-SOEC), which is essential for ACRES, and demonstrated CO2 electrolysis by MS-SOEC. Solid Oxide Electrolysis Cell (MS-SOEC), which is essential for ACRES, and demonstrated CO2 electrolysis by MS-SOEC. From the experimental results, the quantitative potential of ACRES was clarified. The above results show that the development of MS-SOECs enables large-scale ACRES by using large-area stacks.
