Ipcc special reort on co2 capture & storage

The IEA Greenhouse Gas R&D Programme (IEA GHG) has been actively involved with the drafting of the IPCC Special Report on CO2 Capture and Storage (SRCCS) for the last two years. The report was formally approved and accepted by IPCC Working Group III and 24 Session of the IPCC in Montreal, on 26th September 2005. The report comprises the Summary for Policy Makers (SPM), the Technical Summary (TS) and the main full report. Copies of the SPM and TS are now available on the IPCC web site at www.ipcc.ch. The report was formally presented by the Co-chairs (Bert Metz and Ogunlade Davison) of Working Group III of the IPCC on 26th September 2005. A copy of the presentation and the web cast of this event can also be found at www.ipcc.ch.

The report has involved an extensive drafting process involving technical experts on CO2 Capture and Storage (CCS) drawn from around the world. The IEA GHG Programme, its active members and associates supplied three of the 9 co-ordinating lead authors and provided authors to 6 out of the nine technical chapters of the full report. The SRCCS is a review of peer reviewed literature available in the public domain before December 2004. Many of IEA GHG’s own technical reports were drawn upon as reference literature for the report, as were papers in the proceedings and peer reviewed journals that developed after the GHGT conferences which IEA GHG organises.

The report indicates that geological storage of CO2 has significant potential as a mitigation option. Ocean storage, however, is at an earlier developmental stage and more research is needed to assess the suitability of this option. Mineral carbonation is considered to be very energy intensive and there are concerns about its environmental impact. Industrial uses of CO2 are not expected to contribute significantly to the abatement of CO2 emissions.

The IPCC SRCCS is expected to assist the technology in gaining international acceptance and therefore move the technology towards widespread implementation. IEA GHG plan to assess the impact the report has had on the CCS debate and with policy makers over the coming months. In addition, IEA GHG are currently reviewing the gaps in knowledge identified in the SRCCS with a view to providing guidance to its members on key research and investment needs to address these gaps.
