Sharing CCS knowledge in Ponderrada

Monday, 2 June 2014

The European CCS Demonstration Project Network shared the latest activities and learnings from the CCS demonstration projects at a knowledge sharing event hosted by CIUDEN and held in the Technology Development Centre for CO2 capture, located in Cubillos del Sil in the vicinity of Ponferrada, Spain.

The meeting brought together representatives from all current Network members, joined by the representatives from the Crown Estate, the European Commission Directorate for Energy and from two former Network members, the Belchatow project and the Porto Tolle project, who presented the key findings and lessons learnt from confidential final reports. Public versions of these reports are being developed by the Secretariat of the Network.

The meeting, moderated by John Scowcroft, the Network Project Manager, started with updates from the European Commission on the EU’s 2030 framework for climate and energy and the CCS directive evaluation process.

The representative from DG Energy presented the current legislative framework for CCS and the available financial instruments, such as Horizon 2020 and Connecting Europe Facility. He outlined the targets proposed in the 2030 framework communication and the new governance system proposed by the Commission, which is based on national decarbonisation plans to be drawn up by the Member States. These plans should set out domestic technology choices, including CCS, to achieve national GHG emission reduction targets.

The representatives of DG Climate covered the state of transposition of the CCS directive in various Member States and presented the timeline and scope of the CCS directive evaluation, which in addition to the mandatory provision due for the review, covers also broader, CCS-related, energy and climate policy considerations. The CCS evaluation survey has been made available now to all interested stakeholders.

These two topics are of great interest to the Network members who, in addition to sharing the technical knowledge resulting from the demonstration projects, decided to play a more active role in policy decisions through collective advice and recommendations based on the projects experience

The representatives of ENDESA provided a thorough overview of the Front End, Engineering and Design (FEED) study report developed for the OXYCFB300 Compostilla Project. The report is available for download here.

The OXYCFB300 Compostilla Project is an integrated commercial CCS demonstration project and one of the 6 CCS demonstration projects funded by the European Energy Programme for Recovery (EEPR). The project was developed between 2009 and 2013 by a partnership formed by ENDESA, CIUDEN and FOSTER WHEELER ENERGIA Oy. ENDESA was the coordinator for the Project and the FEED works; CIUDEN played a key role in the technological development,constructing and performing tests at three Technological Development Plants (TDPs), including oxy-firing and integration tests in a 30MWth Oxy-Circulating Fluid Bed (Oxy-CFB) boiler while Foster Wheeler acted as the technological developer of the Circulating Fluidised Bed (CFB) oxy-fuel technology.

The key FEED study report conclusions presented at the meeting include:

  • Capture: The process has been successfully validated with more than 2500 hours of operation with different fuels and under diverse operational conditions. The technology has room for improvement and new developments are going to be validated during the next years.
  • Transport: The most economically and environmentally feasible CO2 -pipeline route was selected among the three possible routes presented in the basic Project and the proposed CO2 transport solution is based on a mature technology.
  • Storage: CO2 storage in the Duero site seems to be technically feasible with the required capacity to store the total amount of the CO2 produced in the lifetime of the OXY-CFB-300 project.

The group had an opportunity to visit the facilities of the Technology Development Centre (TDC) for CO2 capture and transport including the laboratories and the advanced equipment for the development of oxy-combustion technologies and the nearby PISCO2 project – a pilot plant for CO2 injection into soils. The central part of the CIUDEN’s TDC consists of two boilers: 20 MWth pulverised coal (PC) boiler and 30 MWth circulating fluidised bed (CFB) boiler. It has been demonstrated that the CFB boiler can be successfully integrated and operated with the CO2 Compression and Purification Unit (CPU) in a safe and reliable way in order to obtain a near-zero emission plant

The CIUDEN team delivered a preparatory briefing before the site visit:

The second day of the meeting was dedicated to the usual knowledge sharing sessions within the three thematic groups: Regulatory Development, Transport and Storage.

The Regulatory Development session started with updates from the Sleipner, ROAD, Compostilla and Don Valley projects and then focused on preparations to the CCS directive review and discussions around formulating the Network’s response to the 2030 framework proposal.

The thematic workshop on CO2 transport started with the updates from the ROAD and Sleipner projects and an overview on permitting procedures from the Compostilla project. The corrosion studies in CO2 pipelines were presented by CIUDEN.

Storage group focused on project updates together with inputs from Don Valley project regarding UK business models for aquifer storage and CO2 EOR. The Compostilla project representatives presented previous work undertaken regarding investment costs and future perspectives. The Crown Estate representative participated in the Storage session presenting the North Sea Basin Taskforce, focusing on the European Projects of Common Interest and introducing the CO2Stored project and database.

Detailed reports from theses session are being prepared by the Network Secretariat and will be published at: http://ccsnetwork.eu/
