Project description
The future OXYCFB300 Project is devoted to demonstrate the CCS value chain(Capture + Transport + Storage) as one of the expected 12 commercial sizedemo projects to be finally within the EU SET (Strategic Energy Technology)Plan.
• The Project has been selected in the EEPR Program to complete, during the2009-2012 period, all the studies, pilot size test, and engineering (FEED) toallow by mid-2012 the Investment Decision (FID) for the final constructionallow by mid 2012 the Investment Decision (FID) for the final constructionphase by the final project promoters.
• As beneficiaries of the EEPR a consortium between ENDESA GENERACIÓN,C OCIUDEN and FWEOy has been created to develop the initial phase.
