A MESSAGE FROM THE PRESIDENT
From Japan to the World~ with a view towards the social implementation of CCS ~There are high expectations for CCS as a measure against global warming, andaccording to the “Net Zero Roadmap” published by the IEA (International EnergyAgency) in September 2023, the global CO2 capture by CCUS required to achieve netzero in 2050 is projected to be approximately 6 billion tons per year.
In Japan, the Ministry of Economy, Trade and Industry published the “Final Summaryof the CCS Long Term Roadmap” in March 2023. In June of the same year, sevenprojects envisioned to begin storing CO2 emitted in Japan by JFY2030 were adopted as
potential model projects by a national agency as “Advanced CCS Projects”.
Furthermore, with the enactment of the CCS Business Act in May 2024, steps are
steadily being taken toward the social implementation of CCS by 2030.
Established in 2008 for the purpose of investigation, research and development of CCS technology, Japan CCS Co.,
Ltd. has been commissioned by the Japanese government and other entities to conduct four projects: “TomakomaiCCS Demonstration Project”, “Investigation of Potential CO2 Storage Sites”, “Research, Development andDemonstration Projects on CO2 Ship Transportation”, and “Project to Promote the Creation of Circular Carbon
Society Model through CO2 Recycling”.
The Tomakomai CCS Demonstration Project was commenced in JFY2012, and with the understanding andcooperation of the local community, the project successfully achieved the target of 300,000 tonnes cumulative subseabed CO2 injection in November 2019, confirming that “CCS is a safe and secure system”. In the investigation ofpotential CO2 storage sites which was started in JFY2014 (contract was concluded in JFY2023), it was estimatedthat there are geological formations (reservoirs) suitable for storing a total of 16 billion tons of CO2 at 11 sites, andthe results have been reflected in the CCS Long Term Roadmap. Furthermore, in the CO 2 ship transportation
demonstration project from JFY2021, we have commenced construction of facilities that will enable bi-directionaltransportation of liquefied CO2 between the Maizuru and Tomakomai offices, and plan to complete construction
this fall and conduct CO2 ship transportation demonstration between Maizuru and Tomakomai.
Aiming for carbon neutrality in 2050, we view as our mission the contribution towards the realization of the national
policy to establish the social foundation for CCUS by 2030. To this end, harnessing the technology and know-howthat we have nurtured on CCS, we will unite our efforts to continue our role in reaching out to the international
community.
We ask for your continued understanding and support.
June 2024

PROJECTS■ Commissioned Projects/Project Framework■ Tomakomai CCS Demonstration Project (JFY2012~)
Commissioned by NEDO
As a result of various field surveys and studies, the project location was narrowed down from 115 candidate sites inJapan, and following a government review meeting, the decision was made to conduct the project in TomakomaiCity, Hokkaido Prefecture in February, 2012.
During the four years between JFY2012-2015, the facilities to capture high purity CO2 from gas containing CO2
generated from a hydrogen production unit of a refinery and to inject the CO2 into the subsurface were designed andconstructed. Also, an existing investigation well was converted into an observation well, and two observation wells
and two injection wells were drilled.
At the same time, in order to confirm that the CO2 injection
into the reservoir does not affect the surrounding
environment, a monitoring system for formation andearthquake data was installed, and baseline data prior toinjection was obtained. In addition, since the formations
where the CO2 is stored are under the seabed, a preliminary
survey of seawater and marine organisms was conducted inaccordance with the Act on Prevention of Marine Pollution
and Maritime Disaster.
Having completed this preparatory work, from April 2016,

Tomakomai CCS Demonstration Project Center

Japan CCS commenced injection of CO2 into a formation about 1,000 meters below the seabed in the port area ofTomakomai Port, with the aim of achieving 300,000 tonnes of cumulative injection. The monitoring work beingconducted includes monitoring the behavior of the injected CO2 (migration, distribution), marine environmental
surveys, etc., to confirm that there is no seepage of CO2, as well as continuous monitoring of micro-seismicity andnatural earthquakes. On November 22, 2019, the CO2 injection reached the target of 300,000 tonnes, and injection
was terminated the same day. Monitoring work is being continued after termination of injection.
In addition, obtaining the understanding and trust of the community where the project is being conducted is an
important objective, and panel exhibitions, site tours of the demonstration plant, lectures for various organizations
and students, and science experiment classes for children have been continued from the beginning of the project.
Furthermore, domestic and international exhibitions and presentations, public relations activities through ourwebsite, YouTube and SNS are being conducted in order to enhance public acceptance of CCS.

Location map■ “Project to Promote the Creation of Circular Carbon Society Modelthrough CO2 Recycling” by the Global Environment Bureau, Ministry of theEnvironment (JFY2021~JFY2024)
Commissioned by MOE
In August 2021, a consortium of 6 companies*1 including Japan CCS was commissioned to conduct “Project toPromote the Creation of Circular Carbon Society Model through CO2 Recycling” by the Global Environment
Bureau, Ministry of the Environment.
In achieving the targets of the Paris Agreement, there are high expectations for environmental innovations including
CO2 capture, storage and recycling, making renewable energies into mainstream power sources, expanding the useof hydrogen, and decarbonization of fuels. Also, in the aviation industry, the International Civil Aviation
Organization (ICAO) has defined CO2 emissions reduction targets in CORSIA (Carbon Offsetting and Reduction
Scheme for International Aviation) and aiming for the use of SAF*2 in aviation as an effective means of reduction
strongly urges its stable production and supply.
The P2C*3 plant being studied in this project will use artificial photosynthesis technology to reduce the CO2

captured from emission sources into CO, which will then be reacted using the FT synthesis*4 process with hydrogen
originating from renewable energy to produce liquid fuels such as jet fuel, light oil, etc.
P2C is expected to significantly reduce the amount of
CO2 emissions and greatly contribute to achievingcarbon neutrality.

Regional Circular Carbon Society Model (Illustration)■ Investigation of Potential CO2 Storage Sites (JFY2014~JFY2023)
Commissioned by NEDO
In order to conduct CCS, geological formations that can stably store large amounts of CO2 are required. According
to surveys conducted between JFY2005-2012, the geological formations in Japan are estimated to have a totalstorage potential of about 240 billion tons of CO2. Although the total storage potential is considered to be sufficient,more detailed investigation is required to determine how suitable individual candidate sites are for storage.
For this reason, the Ministry of Economy, Trade and Industry and the Ministry of the Environment jointly conducted
the "Investigation of Potential CO2 Storage Sites" from JFY2014 to 2023, commissioning the project to Japan CCS.
In this project, at candidate sites with expectations for large storage potential, seismic surveys and analysis ofexisting well data were conducted, and evaluation of the geological structure, reservoirs and cap rocks wasimplemented.
The main achievements of this project are: (1) Detailed evaluation utilizing 3D seismic data completed at 11 sites
estimated the total storage potential (volumetric method) to be approximately 16 billion tonnes (as of March 2023);(2) The results of the project including annual reports, technical manuals, acquired data and evaluation results weretransferred to JOGMEC. A framework has been prepared in order that private CCS companies may utilize the dataand results obtained in this project.
