1 CO 2 sorage in coal The RECOPOL projec Neherlands Insiue of Applied Geoscience TNO - Naional Geological Survey Henk Pagnier, Frank van Bergen

2 Wha is RECOPOL? The RECOPOL projec is an funded combined research and demonsraion projec o invesigae he possibiliy of permanen subsurface sorage of CO 2 in coal. The field demonsraion experimen is he firs of i s kind ouside Norhern America RECOPOL sands for: Reducion of CO 2 emission by means of CO 2 sorage in coal seams in he Silesian Coal Basin of Poland The RECOPOL projec 2

3 Why RECOPOL: he Kyoo proocol has commied a CO 2 emission reducion on Kyoo climae conference in 1997 CO 2 -emissions reduced wih 8% in wih respec o level of 1990 Measures can be financed by CO 2 credis/axes IEA has esimaed esimaed he price in an operaional marke a $32 per on of avoided carbon (2000) CO 2 emission in he Neherlands CO2 emission [Monnes] Kyoo commimen Norway operaes a ax of 40 Euro/onne CO 2 European parliamen discusses a ax of 50 Euro/on CO 2 Targe price in he Neherlands is currenly Year Euro/onne 3

6 Main quesions o be answered by he RECOPOL projec Is subsurface sorage of CO 2 in coal, while simulaneously producing CBM, a echnically viable opion under European condiions? Is subsurface sorage of CO 2 in coal a safe and permanen soluion? How much CBM is produced for each onne of injeced CO 2? Can subsurface sorage of CO 2 in coal be applied on a larger scale in an economical and social accepable way? Wha are he main crieria (geological/echnical/economical/ social) for any coal basin, in or ouside Europe, o be suiable for his echnique? The RECOPOL projec 6
