abstract = {The Mae Moh lignite-fired power plant is the only lignite-fired power plant and is the main point source of CO2 emissions in Thailand. This power plant uses lignite supplied from the Mae Moh lignite open-pit mine in the same vicinity. Carbon dioxide sequestration technologies can play a crucial role in reducing carbon emissions in the energy sector, particularly in coal-fired power plants. This case study provides the first assessment of the potential for geological CO2 storage in coal seams at the Mae Moh coal mine in northern Thailand based on literature reviews. The Mae Moh Basin is a rift basin with a complex normal fault and contains coal seams at different depths separated by claystones. The geological setting potentially offers favorable conditions for the geological storage of CO2 in the coal seams through a combination of physical and chemical trapping mechanisms. The findings suggest that the Mae Moh coal mine is suitable for geological CO2 storage, especially in K and Q coal seams. However, leakage risks, storage capacity, and CO2-water-coal reactions could be problematic. Thus, more subsurface studies should be carried out, and more detailed criteria should be considered before CO2 sequestration is undertaken in the Mae Moh coal mine.}
