To establish a technology for effective utilization of CO₂ separated and captured from exhaust gases from thermal power plant, We aims to commercialize the “Gas-to-Lipids Bioprocess” a two-stage fermentation consisting of a process for fixing CO₂ to produce acetic acid, and a process for synthesizing high value-added lipids, edible oil raw materials, chemical raw materials, etc. from the acetic acid. The bench-scale testing equipment installed at the R&D and Demonstration Base for Carbon Recycling at Osaki-Kamijima will be improved with the aim of improving economic viability and further increasing production efficiency, and the effectiveness will be verified and the amount of CO₂ reduction will be evaluated to obtain knowledge that will contribute to early commercialization.

In the demonstration research area of Osaki, we will demonstrate CO₂ fixation technology to Magnesium Carbonate by using 20 ton/day of seawater. Magnesium Carbonate will be used for concretes and building materials such as wall materials, and the manufacturing method for these materials will also be developed at the same time. As a summary of this project, feasibility study will be conducted based on the results obtained in the demonstration, and an economic evaluation will be conducted.

This project will demonstrate carbon-recycled LPG production using CO₂ and H₂. Based on results from a past three-year NEDO project, we will, over two years from FY2025, improve the catalyst, establish mass production methods, design a bench-scale plant, and evaluate technical feasibility for domestic implementation.

In this project, carbon dioxide (CO₂) emissions from coal-fired power plants and industrial facilities will be utilized as a resource. Large-scale cultivation technology for marine diatoms, which can be used as high-value-added functional chemicals with high production efficiency, will be demonstrated. Preliminary findings from the demonstration data set indicate the necessity of revising the integrated system plan as a CCU solution. This revision will facilitate discussions on the introduction of solutions to CO₂ emission sources and the social implementation of carbon recycling technology.

CO₂ is directly decomposed with high efficiency using electronic energy from atmospheric pressure plasma, and CO is produced that is useful in the manufacture of synthetic fuels and chemical products. Unreacted CO₂ is recovered as ammonium hydrogen carbonate with blue/green ammonia as a reactant. We will establish a leading carbon recycling system that aims to reuse raw materials for methanation represented by methane synthesis.

Diamond electrode, a next-generation electrode material, has excellent durability and unique electrochemical properties, and can selectively and efficiently produce formic acid by electrolytic reduction of CO₂. In this project, we will integrate the elemental technologies for formic acid production by electrolytic reduction of CO₂ using diamond electrodes as well as its separation and recovery, and construct a laboratory-scale integrated system that can continuously produce formic acid. In addition, a bench-scale integrated system will be constructed to verify the feasibility of practical application.

With the goal of contributing to a carbon-neutral society and a circular economy, we are conducting research and development on carbon-recycling silicon carbide (CR-SiC) synthesis using advanced resource recovery technologies for silicon-based waste. Building upon our previously established CO₂ utilization technologies, this initiative aims to address two key technical challenges: the development of purification methods for producing high-purity CR-SiC powder, and the utilization of low-grade silicon-based waste.

This project aims to establish a carbon recycling platform utilizing microalgal biotechnology. The platform will focus on microalgal biofilm culture (substrate-based cultivation) as a high-efficiency method for converting CO₂ into biomass. A minimal operational scale biomass production system will be developed and its performance evaluated through controlled indoor experiments, as well as field-scale outdoor trials. In parallel, a series of downstream processing technologies will be developed and validated for the manufacturing of target chemical products using microalgal biomass. Finally, the entire process -from cultivation to utilization- will be comprehensively assessed using LCA and socio-technical implementation modeling to evaluate its overall feasibility and potential for real-world implementation.

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.

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.
