CCS / CCU

Contributing to the Realization of a Decarbonized Society through Solutions for Carbon Capture Utilization and Storage

The adoption of next-generation energy solutions, such as renewable energy and hydrogen, is gaining momentum in line with the accelerating global drive towards decarbonization. Reducing the environmental impact of existing fossil fuels by controlling and utilizing carbon dioxide (CO₂) emissions is essential to meeting increasing energy demand associated with the economic growth of emerging countries.

Technologies for Carbon dioxide Capture and Storage (CCS), capturing CO₂ emitted from industrial activities, or capturing it from the atmosphere, for injection and storage underground, and Carbon dioxide Capture and Utilization (CCU), also known as carbon recycling, effectively utilizing captured CO₂ as a resource.

Chiyoda continues to contribute to reducing carbon emissions and associated environmental impacts by providing solutions for CCS and CCU.

Chiyoda‘s CCS Initiatives

Cleaner LNG plant Construction to Reduce CO₂ Emissions

As the global drive towards a decarbonized society accelerates, the demand for environmentally friendly LNG Plants (‘Cleaner LNG Plants’) with reduced CO₂ emissions is a major development concept for the LNG industry. Chiyoda has a pioneering track record in the construction of cleaner LNG plants by implementing large-scale CCS facilities to reduce CO₂ emissions during operation.

A General Licensing Agreement with Mitsubishi Heavy Industries, Ltd. for CO₂ Capture Technologies.

The strategic general licensing agreement with Mitsubishi Heavy Industries, Ltd. (MHI) for CO₂ capture technologies promotes the licensing of MHI’s CO₂ capture technologies, ie: the 'KM CDR Process^TM' (Kansai Mitsubishi Carbon Dioxide Recovery Process) and the 'Advanced KM CDR Process^TM' jointly developed with The Kansai Electric Power Co., Inc., to be applied to CO₂ capture projects in Japan.

MHI is a leading licensor of CO₂ capture technologies, with a track record of delivering CO₂ capture plants worldwide. Demand for carbon dioxide capture, utilization and storage (CCUS) is expected to grow in Japan and this partnership builds on our engineering, procurement and construction (EPC) activities, further strengthening Chiyoda’s Japanese CCUS project capabilities.

About MHI Group’s CO₂ capture technologies

MHI Group has been developing the 'KM CDR Process^TM' (Kansai Mitsubishi Carbon Dioxide Recovery Process) and the 'Advanced KM CDR Process^TM' in collaboration with the Kansai Electric Power Co., Inc. since 1990. As of May 2025, the Company has delivered 18 plants adopting these processes. The 'Advanced KM CDR Process^TM' adopts the 'KS-21^TM' solvent, which incorporates technological improvements over the amine-based 'KS-1^TM' and offers superior regeneration efficiency and lower deterioration than the 'KS-1^TM', and it has been verified to provide excellent energy saving performance, reduce operation costs, and result in low amine emissions.

CCU

Chiyoda is actively engaged in technology development and demonstration projects related to CCU, utilizing our expertise in scale-up technology and engineering expertise in the oil and gas sector and environmental field, including:

Joint Technology Development centered on Solid Sorbent Materials to Reduce Low-Concentration CO₂ Separation and Recovery Costs

As part of the New Energy and Industrial Technology Development Organization (NEDO) Green Innovation Fund project (2022-2030) for carbon neutrality in natural gas utilization, Chiyoda is undertaking the development and demonstration of core solid sorbent material technology to reduce costs of the separation and recovery of low-concentration CO₂ from gas turbine exhaust gases.

As part of a NEDO project(2020-2024) and its subsequent project for the development of CO₂ utilization technology in the production of chemicals aimed at replacing existing fossil fuel-derived chemicals, Chiyoda is engaged in cutting-edge technology development to produce paraxylene (a raw material for PET and polyester) using CO₂ as a raw material.

In a collaborative initiative between industry, academia and government as part of the NEDO Moonshot Research and Development Program from FY2020 to FY2029, Chiyoda is engaged in the research, development and demonstration of an innovative large-scale CO₂ utilization system, primarily based on electrochemical processes.

Demonstration and Basic Design Projects

Chiyoda is participating in a wide range of projects, including basic design and demonstration and testing facilities, related to the social implementation of decarbonization technologies, and are collaborating with clients from early project stages to expand our expertise and generate new projects.
