Tomakomai CCS Demonstration Project in Japan

The Japanese government has started a large-scale CCS demonstration project at the Tomakomai Area in Hokkaido for the period JFY 2012-2020. From JFY 2016 to 2018, 100,000 tonnes/year or more CO2 derive from an industrial source is scheduled to be injected and stored in two separate reservoirs (saline aquifers) approximately 1100m and 2400m depths respectively, below the seabed in offshore the Tomakomai Port. A series of monitoring consisting of time-lapse 2D and 3D seismic surveys, temperature and pressure measurements of the reservoirs, micro-seismicity and natural earthquake observations in and around the reservoirs is planned before, during and after the CO2 injection until JFY 2020 along with the marine environmental surveys.
