3 Many Scientists with high international Reputation support CCS-Technology without CCS, global climate protection might be hardly possible Dr Edenhofer, Co-Chairman of Work Group III of the International Panel Climate Change (IPCC), whoever ignores CCS, does not act in a liable way regarding climate protection Dr Matthes, Coordinator Energie und Klimaschutz Öko-Institut, ambitious international climate protection without CCS is not possible Prof Dr Schellnhuber, Director of the Potsdam- Institutes für Klimafolgenforschung, if we face the challenge of climate change, every measure, every technology we can achive has to be taken and has to be brought to an applicable and commercially reasonable state...

8 IGCC-CCS: Project planning and tasks within the RWE Group RWE Power RWE Dea Production Transportation Storage Goldenberg/Hürth near Cologne is the most economically viable location for the IGCC- Power station transportation by pipeline is the most suitable alternative in terms of economy, ecology and safety Saline formations in northern Germany are the most suitable storage for Pipeline Experiences in EOR in the USA -Pipeline-Experiences: Since early 70s in the USA is used for enhanced oil recovery. 5 MM. t/a, 330 km, 14 inch, 130 bar Therefore approx. 35 MM t are transported safely through the states. Over 3000 km of pipelines are already installed. 10 MM. t/a, 660 km, 24 inch, 130 bar 7 MM. t/a, 350 km, 20 inch, 130 bar 19 MM. t/a, 800 km, 30 inch, 130 bar Pipelines are the most secure option to transport over distance. 8

EU Commission End of 2008 EU - CCS framework Draft CCS framework dir. EU Parliament est. In parallel: development of national legislation EU - CCS framework granted Late 2010/Early 2011 Binding legal framework Establishment of funding instruments EU directive CCS in EU-ETS National Implementation? Development National funding instruments Clarity about CCS funding instruments to make sure that CCS becomes an economic option and to help industries with safety on investment RWE is leading the way in CCS technology with enormous challenges There is an urgent need for a legal framework on CCS Storage in Germany Thank you for your attention!
