Abstract: CO2 geological storage in coal seam is one of the four technical scheme of CCS, is an effective way to reduce CO2 emissions. According to a new round national CBM resources survey result of coal seam gas recoverable reserves, based on the method for calculating CO2 geological storage potential evaluation in the main coalfields of our country recommended by carbon sequestration leaders forum (CSLF), CO2 geological storage potential of the buried depth of coal seam in the 1000 ~ 2000 m are calculated, the total potential of coal seam gas of 28 bearing basins in China are 98.81×108t. Moreover, the basins are Ordos basin, Junggar basin, Tuha basin, Hailar basin, which the CO2 geological storage potential are more than 10×108t. The four basins total storage potential is 68.45×108t, accounted for 69.27% of national total storage potential, will be the main basin coal field CO2 geological storage in our country.
