Flexi-burn OXYCFB300 Compostilla European Energy Program for Recovery (EEPR) The origin of the European Energy Programme for Recovery (EEPR) is the global 200 billion European Economic Recovery Plan presented by the Commission on 26 November 2008. On 9 December 2009, the European Commission announced details of the six CO 2 capture and storage (CCS) projects which will receive funding ( 1 billion in total) under the EEPR to develop the projects initial stages. Each project received 180 M funding (except Porto Tolle 100 M ) Tecnologie e Processi Innovativi per la Sostenibilità Ambientale degli Impianti di Combustione P. Cotone page 13

Flexi-burn OXYCFB300 Compostilla Project description The future OXYCFB300 Project is devoted to demonstrate the CCS value chain (Capture + Transport + Storage) as one of the expected 12 commercial size demo projects to be finally within the EU SET (Strategic Energy Technology) Plan. The Project has been selected in the EEPR Program to complete, during the 2009-2012 period, all the studies, pilot size test, and engineering (FEED) to allow by mid-2012 the Investment Decision (FID) for the final construction phase by the final project promoters. As beneficiaries of the EEPR a consortium between ENDESA GENERACIÓN, CIUDEN and FWEOy has been created to develop the initial phase.
