INTRODUCTION

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.

Research of Selective Synthesis Technology of Chemical Products for Carbon Recycling

Research of Selective Synthesis Technology of Chemical Products for Carbon Recycling

It has been required that we use CO₂ for producing chemical products in an effort to transform ourselves into a decarbonized society in the future. In line with this objective, our focus is now on attaining a synthesizing technique by using CO₂, to be more specific, a technology for synthesizing para-xylene, a raw material whose demand is expected to grow in the future due to its use for fiber production, etc., by using CO₂. This project aims to develop technologies for producing para-xylene by using the methanol being synthesized from CO₂ and H₂. The technologies include higher-performance catalysts for synthesizing methanol from CO₂ and H₂ as well as catalysts with an improved formation ratio of para-xylene, the useful product among the xylenes.

Development of Gas-to-Lipids Bioprocess

Development of Gas-to-Lipids Bioprocess

To establish a technology for effective utilization of CO₂ separated and recovered in next-generation thermal power generation, we developed a biorefinery technology called “Gas-to-Lipids Bioprocess” via two-stage fermentation, which consists of a process to generate acetic acid by immobilizing CO₂ and one to synthesize high value-added lipids and chemical raw materials from the acetic acid. While conducting bench-scale tests of individual and integrated manufacturing processes, we will evaluate their environmental impact, technological competitiveness, and feasibility and strive to establish the technology and manufacturing processes.

Establishing a Research Base and Developing Technologies that Lead to Increased CO₂ Utilization Rate for the Production of Microalgae-Derived SAF

  • Environmental regulation will enable production and cultivation tests of diverse microalgae species in environments that simulate various climates, as well as trials of multiple drying and extraction processes.

    Promote research and systematization of results through standardization of methods and conditions of measurement/analysis and of cultivation.

Some species of microalgae store oils and fats during growth, which can be extracted and reformed to produce sustainable aviation fuel (SAF). In particular, the production of SAF from microalgae is positioned as a Carbon Recycling technology as it utilizes a mechanism that absorbs carbon dioxide from the atmosphere through photosynthesis. If a production technology for microalgae-derived SAF can be established, it is expected to contribute to the reduction of fossil-derived fuels and help prevent global warming. In order to do so for microalgae-derived SAF and further develop it as an industry, we will establish a research center capable of verifying production and cultivation technologies of various microalgae and work on measurement/analysis methods of microalgae for systematizing research results as well as the standardization of condition settings.

Research & Development of CO₂ Fixation by Microalgae and High-Value Ingredients Production

微細藻類によるCO₂固定化と有用化学品生産に関する研究開発

When supplied with CO₂ and light energy, microalgae fix carbon in various forms in their cells via photosynthesis. For this research theme, we breed marine microalgae using a combination of random mutagenesis and genome editing to create strains with high productivity. We develop high-density culture techniques using selected algal strains. Useful chemicals (EPA, fucoxanthin) are extracted from the biomass harvested from the large-scale cultivation. Using the residues after extraction of the chemicals, we develop bioplastics which enable long-term CO₂ storage . We aim to integrate these technologies to propose an algae biomass production system for power plants and various factories.

Development of a CO₂ decomposition and reduction process using atmospheric pressure plasma

大気圧プラズマを利用する新規CO₂分解・還元プロセスの研究開発

While generating CO by directly decomposing CO₂ using renewable energy and recovering the unreacted CO₂ as carbonate, we will conduct leading research on a new process for the direct synthesis of urea,etc. from CO. In other words, optimization of reaction conditions and reactor structure, as well as scale-up research, will be conducted for a reactor that efficiently decomposes CO₂ into CO using atmospheric pressure plasma (Reactor I), one that efficiently converts unreacted CO₂ into carbonate (Reactor II), and one that efficiently directly synthesizes urea,etc. from CO using atmospheric pressure plasma (Reactor III) to develop a novel CO₂ decomposition and reduction process and evaluate its feasibility.

Research and development of carbon recycled LP gas manufacturing technology and process

カーボンリサイクルLPG製造技術とプロセスの研究開発

In this research, we will develop catalyst and process technologies and review a social implementation model to produce Carbon Recycling LPG using Fischer-Tropsch (FT) synthesis, a method for synthesizing liquid fuels from carbon monoxide and hydrogen. Specifically, we will use carbon monoxide and hydrogen, which are emitted from power plants or are derived from biomass-based carbon dioxide, as source gases to 1) develop catalyst technology suitable for LP gas production by FT synthesis; 2) review the entire production process from source gas to LPG production, purification, and preparation; and 3) review an overall social implementation model from the procurement of raw materials such as biomass resources and storage/transportation of produced LP gas to the use of non-LPG products obtained through FT synthesis.

Development of algal biomass production and application technologies enabling high efficient CO₂ utilization

CO₂の高効率利用が可能な藻類バイオマス生産と利用技術の開発

In this project, we will conduct R&D on both the production and utilization of algae biomass. In the former, a cultivation system will be developed using solid surface cultivation for algae in the gas phase as an elemental technology, which is characterized by its ability to efficiently utilize CO₂ and sunlight and is expected to lead to a high-yield algae biomass production system. In the latter, R&D will be conducted for utilization technologies with steelmaking set for algae biomass purposes. On top of applying algae biomass only to the steelmaking process, we will also consider multifaceted utilization that combines multiple applications for each component. In addition, a search for algae strains with superior usability will be conducted in parallel.

Development of Efficient CO₂-Use Concrete2022 Finished

  • CO₂有効利用コンクリートの研究開発
  • CO₂有効利用コンクリートの研究開発 屋外大型試験

n this project, we will develop technologies to expand the scope of application of concrete that effectively utilizes CO₂. The CO₂ effective use concrete has already been put to practical use in some products, but its scope of application is limited. This is due to technical constraints such as “the process to absorb CO₂ is required in a tank filled with CO₂” and “concerns about rebar corrosion”. At this base, as empirical studies of carbonation technology for various concrete such as cast-in-place and reinforced concrete, we manufacture actual large-scale specimens and conduct various tests. In this project, we will strive for the social implementation of Carbon Recycling technology in the concrete field.
