1 Demonstrating CCS in Italy The Zero Emission Porto Tolle Project Pietro Barbucci Enel - Engineering & Innovation Division IEA WPFF Workshop Genoa, 15 April 2010

2 A CCS demo plant in Italy Why In Italy Enel plans to built 5000 MWe clean coal capacity, substituting existing oil fired or NG fired steam cycles. Clean coal plant characteristics: Closed coal management system η = 45% extremely low pollutant (NOx, SOx; particulate) emission levels Torrevaldaliga Nord Power Plant (3 units, 2000 MWe) almost completed Next project of this kind is Porto Tolle These assets need to be preserved in the carbon constrained scenario CCS retrofit technologies required 2

3 ZEPT- Zero Emission Porto Tolle Project goal To retrofit one 660 MW e coal fired unit of Porto Tolle power station with CO 2 post Porto Tolle combustion capture equipment and start CO 2 underground storage in an off-shore saline aquifer by

4 ZEPT- Zero Emission Porto Tolle Project time schedule Activities carried out in the frame of the EEPR Grant Agreement signed in December 2009 with European Commission 4

5 ZEPT- R&D Supporting Activities CO 2 capture pilot plant At the site of Brindisi coal fired power station a pilot plant for CO 2 separation via amine scrubbing is under commissioning. The plant is installed on the Unit 4. The plant is composed by a flue gas pretreatment section (able to remove completely the particulate and the SO 3 and to reduce SO 2 level below 20 mg/nm 3 ) and by a CO 2 separation unit The plant size is Nm 3 /h, capturing Brindisi about 2,5 t/h of CO 2 Unit 4 Goal to: gain experience in CCU designing and operation, and assess the environmental impact of the process 5

7 ZEPT R&D Supporting Activities Integrated CCS pilot project The first Italian integrated CCS pilot project is under development in the frame of the Eni - Enel cooperation agreement. It will include: Capture Enel s post-combustion capture pilot plant in Brindisi in operation from beginning 2010 and separating at least 5000 tco 2 /y Liquefaction CO 2 liquefaction and criogenic storage system to be built in Brindisi treating the CO 2 produced by the pilot capture plant Transport 230 tracks per year CORTEMAGGIORE Storage ENI gas field in Cortemaggiore (Piacenza). Injection start summer Total CO 2 injected: ton BRINDISI It is also forseen to build in Brindisi a closed loop CO 2 pilot pipeline to develop knowledge to be used in demo design. 7

10 Financial challenges in demonstrating and deploying CCS 10

11 Financial feasibility of CCS demos Construction and operational risks Project promoters are bearing relevant constructions and operational risks Incremental costs of CCS Public needs to cover most of the economic gap Cost of a power plant without CCS The economic gap for a typical CCS demo project is of the order of 1b 11

12 Public funding assumptions for ZEPT demo A grant from the EEPR fund 100 M under the Grant Agreement signed in Dec A substantial contribution from NER 300 fund 2010 Call for proposals expected by July A significant funding from Italian Government The Energy Law (99/2009) provides for economic support to CCS demos EU ETS auction revenues could be used 12

13 ZEPT- Decision gates Prelim. Invest. Decision Apr Years Cost evaluation not to exceed Final Invest. Decision Feb NER 300 bid Financial Plan closure NOTICE TO PROCEED Construction start June 2013 CCS demo permitting 13

14 CCS economic perspectives Need to start focusing on this phase Source:ZEP-TP EU Demonstration Programme for CO 2 Capture and Storage (CCS), 10 th Nov,

15 Allowing CCS deployment start-up Power sector is ready to do its part (i.e. CO 2 Capture and Compression) but CCS can not be deployed without the full involvment of oil and gas industry A transport and storage infrastructure is needed establishing the appropriate policy framework Financial mechanism to cover the economic gap until CCS competitiveness is reached (Feed-in tariffs?) 15
