A message from Mr. Hirofumi, Iwakura, Tomakomai Mayor
Regarding the achievement of 300,000 tonnes of cumulative CO2
injection in the Tomakomai large-scale CCS Demonstration Project(November 25, 2019)

The Tomakomai Project is the first large-scale CCS
demonstration project in Japan, and the data and knowledge
acquired is certain to play an important role in advancingCCS in Japan.
Tomakomai City will continue supporting this project, withthe aim of nurturing understanding for CCS in our region andMr. Hirofumi, Iwakura,Tomakomai Mayor
consciousness of our environment, in order that Tomakomai
may play a leading role towards the establishment of a low-carbon society
where the global environment and a thriving local economy can co-exist.

Summaryu Operation of full chain CCS system from capture to storage has been conductedsuccessfully and target of 300,000 tonnes of CO2 injection has been achieved
u CO2 capture process comprising a two-stage absorption system with a low-pressure flash
tower has achieved significantly lower capture energy than conventional systemu Deviated injection wells from onshore site into offshore reservoirs saved drilling cost andavoided disturbance of local livelihood
u The “Moebetsu Formation” (shallow reservoir) has demonstrated superior injectivity, with
only minor pressure buildup
u Concerns about earthquakes and induced seismicity have been addressedØ Natural earthquakes have not caused any damage to reservoirs
Ø No seismicity (Mw > -0.5) has been detected in/around the depth range of the reservoirs before andduring injectionu Safety and reliability of CCS system has been demonstratedu Project is being conducted with understanding and support of local community
