Test fuels and schedule:

• Test on different fuels (Spanish anthracite, petroleum coke, bituminous coal, lignite and mixtures).

• CFB performs very well in oxycombustion. Small differences compared to air combustion and in linecompared to air combustion and in line with expectations.

• Lower emissions during oxycombustion.

• The origin of the European Energy Programme for Recovery (EEPR) isProgramme 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 CO2 capture and storage (CCS) projects which will receive funding (€1 billion in total) under the EEPR to develop the projects initial stagesdevelop the projects initial stages.

• Each project received 180 M€ funding (except Porto Tolle 100 M€)

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.
