As of September 30, 2016, the Carbon Capture and Sequestration Technologies program at MIT has closed. The website is being kept online as a reference but will not be updated.

Compostilla (OXYCFB 300) Fact Sheet: Carbon Dioxide Capture and Storage Project

Company/Alliance: ENDESA, CIUDEN, Foster Wheeler

Location: Ponferrada, NW Spain

Feedstock: Coal

Size: 30-320 MW

Capture Technology: Oxy-Fuel (using Flexi-Burn CFB technology)

CO2 Fate: 135 km onshore pipeline for sequestration in saline aquifers at 1500m depth

Timing: Capture start 2009. Completed: 2012

Scale up: 320 MW (1 Mt/yr). Operation of the scale up project was scheduled by end of 2015.
The OXYCFB 300 Compostilla Project completed the work that it had committed to carry out under the terms of its EEPR grant by October 2013 and subsequently took a decision not to proceed to full scale demonstration.


Awarded €180 million from EU government in December 2009 as part of European Recovery Programme for the first phase of the project.

The project will also receive an extra €280-450 million in the form of EU Emission Allowances.


The project is also called OXY-CFB-500. This project is unique among those that have received funding from the EU in that it is the only one which is developing Oxy-fuel combustion. In December 2011, the Fundación Ciudad de la Energía (CIUDEN) successfully completed the initial testing phase of oxy combustion in its 30 MW Circulating Fluidized Bed boiler, burning coal using oxygen instead of air.

In December 2011, CIUDEN announced it had successfully tested oxy-combustion in a 30 MW CFB boiler. By October 2012, it had conducted the full CO2 capture process - which it hailed a world first for the oxy-combustion process.

Initially, the OXYCFB300 Compostilla project had an estimated duration of 42 months (mid 2009-2013), but in November 2012 the duration was extended the duration until October 2013 due to the delays caused in tests and in storage programme activities. The plant enabled 800 m3/h of combustion gases to be treated and had a capture capacity of 3-5 tonnes of CO2 per day with efficiencies of 90 per cent.
