Background and Purpose

Background and Purpose

CO₂ is a very high proportion of greenhouse gases generated by humans, and further reduction is needed to protect the global environment. Japan has declared in its “Long-term Strategy as a Growth Strategy Based on the Paris Agreement” (decided by the Cabinet on June 11, 2019) that it will work to reduce greenhouse gas emissions by 80% by 2050. CO₂ reduction is a global issue that requires urgent action. In addition, the “Carbon Recycling Technology Roadmap (Ministry of Economy, Trade and Industry, June 2019)” states that CO₂ is regarded as a resource and the policy of controlling emissions by effectively using “Carbon Recycling Technology” is described. Innovative technological development is required.

Under these circumstances, NEDO has launched a research and development program aimed at achieving Moonshot Goal 4 “Realization of sustainable resource circulation to recover the global environment by 2050”, and this project has been adopted as a contractor for this program. The term of the program is set for up to 10 years, from FY2020 to FY2029.

The project focuses on electrochemical technology and aims to develop a process that can capture CO₂, reduce it to useful chemical feedstocks and recycle it, and can also disperse it. Specifically, we are developing an integrated system that captures the dilute CO₂ emitted into the atmosphere and the CO₂ before it is emitted, and electrochemically enriches / reduces it, and produces useful chemical feedstocks using renewable energy as a source. By developing this system, we will build a foundation for carbon recycling.

Quantitative Target for CO₂ Capture and Recycling: 100 million tons/year

This project targets CO₂ emissions that cannot be covered by the introduction of renewable energy and CO₂-free fuel, and has set a quantitative target of 100 million tons/year for CO₂ capture and recycling.

Breakdown of CO₂ emissions in Japan and capture/recycling target of this project

Target Product: Ethylene (C₂H₄)

Ethylene is a typical basic chemical product, with annual production of 6.42 million tons in Japan and 220 million tons worldwide. It is a feedstock for plastics and synthetic fibers, and is used in about half of plastic products, so we consider it to be one of the most important useful chemical feedstocks.
