A pilot site for CO2 storage in coal seams was set-up at Kaniow, Poland. This site consisted of one injection and one production well. About 760 ton of CO2 has been injected into the reservoir from August 2004 to June 2005. A follow-up EC project, MOVECBM, aimed at determining the storage performance of the reservoir, i.e. whether the injected CO2 was adsorbed onto the coal or whether it was still present as free gas in the pore space
The site now provides a valuable opportunity to monitor the post-injection phase of storage evolution.
