Outline

To establish a sustainable social system, it is essential to use limited fossil resources efficiently and to develop alternatives derived from non-fossil feedstocks and energy sources. One promising approach is Carbon Dioxide Capture and Utilization (CCU), which involves converting CO₂—recovered from sources such as combustion flue gas—into valuable products like fuels and chemicals.

The schematic diagram above illustrates a CO₂ conversion process driven by renewable energy. First, hydrogen is produced via water electrolysis powered by renewable energy. Then, CO₂ is separated and captured from combustion exhaust. Finally, hydrogen and CO₂ are reacted in a catalytic reactor to synthesize useful compounds. I have been developing catalytic systems for the selective hydrogenation of CO₂ into methane, methanol, dimethyl ether, and olefins.
