Development of Carbon Recycling Technologies
at the R&D and Demonstration Base
in Osaki Kamijima

At Osaki-Kamijima Island, Hiroshima, located in the middle of the scenic Seto Inland Sea, a center of activity was established based on “Carbon Recycling 3C Initiative” announced by METI in 2019. This center offers companies and universities, aiming to realize a carbon-neutral and decarbonized society, hub of activity to promote their R&D activities. Our aim is to accelerate innovation and practical application of Carbon Recycling by conducting underlying technology development and demonstration in a concentrated and extensive manner.
Furthermore, through showcasing the details and results of their activities we will share Japan’s cutting-edge technologies to the world.

In efforts to curb global warming, reducing CO₂ emissions has become a global challenge. Japan has set a goal of becoming carbon neutral by 2050, aiming to reduce greenhouse gas emissions by 46% from 2013 levels by 2030 and take on the challenge of reaching the 50% mark. Carbon Recycling is currently attracting attention as a way to reduce CO₂ emissions into the atmosphere by reusing CO₂ as a resource for materials, fuel, and other purposes.

So at the Davos meeting in January 2019, Japan referred to the need to recycle CO₂, and in June of the same year, the Ministry of Economy, Trade, and Industry formulated the Roadmap for Carbon Recycling Technologies, a policy which considers CO₂ as a resource, separates and recovers it, and reuses it in form of various products such as concrete, chemicals, and fuels to curb CO₂ emissions into the atmosphere. In the Carbon Recycling 3C Initiative presented by the Ministry in September 2019 and the Environment Innovation Strategy (by Integrated Innovation Strategy Promotion Council) formulated in January 2020, a project was announced to develop Osaki-Kamijima Island in Hiroshima, where such projects on integrated gasification combined cycle (IGCC) and integrated gasification fuel cell cycle (IGFC) are underway, as a demonstration and research center for Carbon Recycling. In December of the same year, the Ministry of Economy, Trade and Industry (METI) took the lead in formulating the Green Growth Strategy towards 2050 Carbon Neutrality in collaboration with related ministries and agencies. In particular, Carbon Recycling will be positioned as one of the key technology areas to realize a carbon-neutral society.

Carbon Recycling, which effectively utilizes CO₂ as a resource, can be used in various fields such as chemicals, concrete/cement, machinery, engineering, fuels for transportation and biotechnology, giving Japan a competitive edge. As Carbon Recycling technology is established, its use is expanded, and costs are lowered, it is expected to develop into a new Japanese industry that will be a major key to reducing the use of fossil fuels and thus helping to prevent global warming in the future.

Designed to accelerate innovation by setting targets, technical issues, and timeframe for Carbon Recycling technologies and sharing them across governments, private companies, investors, researchers, and other stakeholders in Japan and abroad, the Roadmap for Carbon Recycling Technologies was formulated in June 2019 and revised in July 2021 by METI for academics and engineers in various technical fields with the cooperation of the Cabinet Office, the Ministry of Education, Culture, Sports, Science and Technology (MEXT), and the Ministry of the Environment, Japan (MOEJ). To accelerate innovation in Carbon Recycling technologies, it (1) clarifies the current state of technologies and issues for cost reduction and describes steps for technological progress for each material that can use CO₂ as a resource, and (2) sets cost targets for 2030 and 2040 to reach costs equivalent to existing products.
