Direct Injection of Flue Gas into Coal Seams for Carbon Storage and Methane Production


Keywords: , , , , ,

Investigation into the potential for flue gases from a 2400MW coal fired power station to be injected into the nearby deep coal seams under the plant for carbon capture and storage. Directional drilling techniques will be utilised to expose the coal seams with delivery channels for the flue gas and for exit routes for the displaced methane which in turn will be utilised for additional power production at plant. Composite Energy in collaboration with Scottish Power, BG-Group, the Royal Bank of Scotland, the University of Strathclyde and Imperial College London will carry out this project in 2008 / 2009. The study is privately funded and will explore the viability of this technique which offers the potential to greatly reduce the cost of carbon sequestration. The presentation will explore the details of this ground breaking project and the new technologies involved. If successful, future work will consider the CO2 absorption ability of various types of coal from around the world and the juxtaposition of coal fired power stations with such coal fields to estimate the global potential for carbon sequestration arising from a successful trial of this project.
