Tomakomai CCS Demonstration Project –Target of 300,000 tonnes of carbon dioxide (CO2) injection achieved
Tokyo, JAPAN - Japan CCS Co., Ltd. (hereinafter “JCCS”; Head Office: Chiyoda-ku, Tokyo; President:
Shoichi Ishii) announced that it had achieved the target of 300,000 tonnes of CO2 injection at theTomakomai CCS Demonstration Project on November 22, 2019.
JCCS was selected as the contractor for the public tender " Demonstration of CO2 Reduction
Technologies (FY2012)" held by the Ministry of Economy, Trade and Industry of Japan (METI), andunder the national policy aiming towards the practical use of CCS technology by around 2020
commenced a demonstration project in Tomakomai from FY2012 (During 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 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. Also, the conversion of 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 MaritimeDisasters.
From April 2016, targeting annual injection of 100,000 tonnes, CO2 has been 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 300,000 tonnes.
Accordingly, injection has been suspended, whereas monitoring operations* will be continued.
*Monitoring operations
Monitoring will be conducted in order to grasp the behavior (movement, distribution) of theinjected CO2, and 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.

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 toanswer the Japanese government’s call for development of CCS technology as a countermeasureagainst global warming. JCCS is a unique company in the world to be founded and dedicatedexplicitly to developing integrated CCS technology. More information:
