There are many types of geological formations used for CO₂ sequestration. Coal seam is one of them. The characteristics of the coal seam used for CO₂ sequestration are the methane recovery when CO₂ is sequestrated. CO₂ is injected into coal seam not only for the CO₂ sequestration but also for CH₄ recovery (ECBMR).<BR>This paper reports the sequestration mechanism of CO₂ in the coal seam and the world R&D status in this field.<BR>The adsorption is a main sequestration mechanism of CO₂ in the coal seam. In the field scale sequestration, pressure of CO₂ is super-critical. The adsorption volume of CO₂ in coal in that condition is not yet clarified. This adsorption volume is very important for the prediction of sequestrable CO₂ volume.<BR>The present activities on this subject in the United States, Canada, Australia, Netherlands and Japan were reported. For the further studies, the international cooperative R&Ds are necessary. Items for the further R&Ds are summarized.
