For Immediate Release

Release of Summary Report of Tomakomai CCS Demonstration ProjectTokyo, Japan – Japan CCS Co., Ltd. (hereinafter “JCCS”; Head Office: Chiyoda-ku, Tokyo;
President: Shoichi Ishii) herewith announces that the “Report of Tomakomai CCS
Demonstration Project at 300 thousand tonnes cumulative injection” (hereinafter “SummaryReport”) has been issued.
1. Context of Summary Report
Covering the period of project startup in FY2012 through achievement of 300 thousandtonnes cumulative CO2 injection on November 22, 2019, this report summarizes the outcomes
and issues of the Tomakomai CCS Demonstration Project at the time of 300 thousand tonnes
cumulative injection, based on the discussions by a wide range of experts in fields including
mechanical engineering, chemical engineering, geology and geophysics.
2. Background and Current Situation
JCCS was selected as the contractor for the public tender "FY2012 CO2 Reduction Technology
Demonstration Project" held by the Ministry of Economy, Trade and Industry of Japan (METI),
and under the national policy aiming towards the practical use of CCS technology around 2020
commenced a demonstration project in Tomakomai from FY2012. During the 2 years of FY2018
and FY2019, JCCS has conducted the project under the contract “CCS R&D and Demonstration
Related Projects / Large Scale CCS Demonstration Project in Tomakomai” under thecommissioning of the New Energy and Industrial Technology Development Organization(NEDO).
During the 4 years from FY2012 to FY2015, the facilities to capture high purity CO2 from CO2
containing gas emitted by a hydrogen production unit of a refinery - the CO2 source, and thefacilities to inject CO2 underground were designed and constructed. In addition, the conversionof an existing survey well into an observation well, and the drilling of 2 observation wells and 2
injection wells was completed.
At the same time, in order to verify that CO2 injection into the reservoir will not affect thesurrounding environment, a monitoring system to record formation and earthquake data wasestablished, and baseline data prior to injection was obtained. Also, as the reservoir for CO2
storage was to be in the sub-seabed, a baseline survey of seawater and marine organisms wasconducted in accordance with the Act for the Prevention of Marine Pollution and Maritime

Disasters.
From April 2016, targeting annual injection of 100 thousand tonnes, CO2 was injected into aformation 1,000m sub-seabed in the harbor area of Tomakomai Port, as well as experimental
injection into a formation 2,400m under the seabed.
On November 22, 2019, cumulative CO2 injection reached the target of 300 thousand tonnes,
and accordingly, injection has been suspended.
3. Future Plans
Monitoring of micro-seismicity, marine environmental surveys around the storage site, andmonitoring of the behavior (movement, distribution) of the injected CO2 will be continued.
*Monitoring Operations
Monitoring will be conducted in order to grasp the behavior (movement, distribution) of theinjected CO2, micro-seismicity and natural earthquakes will be observed on a 24-hour basis,and marine environmental surveys will be carried out to verify that there is no CO2 leakage.
4. Tomakomai CCS Demonstration Project Milestones
・Startup of injection preparations including design and construction of facilities: April 2012
・Commencement of CO2 injection: April 6, 2016
・Achievement of 300 thousand tonnes of CO2 injection: 7:07am, November 22, 2019

injection achieved” - JCCS Media Release dated on November 25, 2019
About Japan CCS Co., Ltd.: Commissioned by the Japanese government to demonstrate a fullchain CCS system in Tomakomai City, Hokkaido, Japan CCS Co., Ltd. (JCCS) was founded in May
2008 when a group of major companies with expertise in CCS-related fields, including electricpower, petroleum, oil & gas exploration and development, and plant engineering, joined forces
to answer the Japanese government’s call for development of CCS technology as acountermeasure against global warming. JCCS is a unique company in the world to be founded
and dedicated explicitly to developing integrated CCS technology. More information:
