Geochemical Results on the CO2 Georeactor Sequestration Tests at the Ogachi Hot Dry Rock Site, Northeast Japan

This paper reports a preliminary result of field experiments of CO2 sequestration into the Ogachi hot dry rock (HDR) site, where a part of CO2 will be expected to be fixed as carbonates by interaction with rocks (Georeactor; Ca extraction from rocks and carbonate fixation).
