Highlights for Friday, 23 September 2005

On Friday, delegates met in plenary throughout the day and into the night to continue line-by-line deliberations on the draft SPM. In the morning and afternoon sessions, delegates considered the section of the SPM concerned with the current status of CCS technology. In the afternoon, delegates also considered the section of the SPM concerned with the geographical relationship between the sources and storage opportunities for carbon dioxide. In the evening, delegates turned to a consideration of the costs for CCS and its economic potential. The contact group established on Thursday to revise the first two paragraphs of the SPM continued its work, while a new contact group was established to discuss a figure representing the geographical relationship between carbon dioxide emissions sources and storage potential. Earth Negotiations Bulletin coverage stopped at 8.00pm.

Co-Chair Bert Metz (The Netherlands) welcomed delegates, recalled that the SPM had already gone through an extensive review process, and  urged them to move forward to complete its approval.

What is the current status of CCS technology?

BELGIUM noted that a figure representing capture systems was unclear, and proposed using a figure from the Special Report instead.

On the corrosiveness of pipelines for transportation, CANADA proposed removing reference to hydrogen sulphide given its negative connotation, and proposed referring to contaminants instead.

DENMARK, supported by the UK and the NETHERLANDS, proposed emphasizing caprock as an essential trapping mechanism.

Lead Author Peter Cook clarified that caprock is essential unless injection takes place deep enough.

Lead Author Ken Caldeira noted that the consequences of the equilibration between carbon dioxide in the ocean and atmosphere were nuanced and difficult to express in the SPM. 

After further comments from CHILE, NEW ZEALAND and GERMANY regarding clarification of the process and time scale of equilibration, the text  introduced by Co-Chair Metz was accepted.

Co-Chair Davidson introduced the revised text on the reaction of carbon dioxide with metal oxides, and noted that while the technology is still in the research phase, certain applications using waste streams are in the demonstration phrase. 

Discussion then shifted to text on industrial uses of carbon dioxide, which included a proposal by Canada, supported by the US, to insert text that notes that enhanced oil recovery (EOR) is excluded from a statement that the potential for industrial uses of carbon dioxide is small.

GERMANY noted that including such a reference could falsely suggest that EOR is a large opportunity.

JAPAN and KOREA proposed changing the reference to ocean storage direct injection "dissolution type" and "lake type" in the table outlining the current maturity of CCS system components

What is the geographical relationship between the sources and storage opportunities for carbon dioxide?

Discussion for geological storage focused on the type of sources, the distance from sources to storage locations, and the location of sources.

Discussion on ocean storage focused on ocean storage's regional distribution, maturity, location, and existing literature. JAPAN underscored that the ocean storage potential varies regionally, and that Japan has more potential for ocean than geological storage.

AUSTRIA, AUSTRALIA and others expressed concern that the language implied more technical maturity and scientific analysis for ocean storage than actually exists.

CHINA, supported by BANGLADESH, EGYPT and SAUDI ARABIA, and opposed by NORWAY and FINLAND, proposed emphasizing that the proximity of large point sources to storage sites was uncertain. Above photo L-R: Ronald Flipphi (The Netherlands) in discussion with Kong Xiang Wen (China) and Leo Meyer (IPCC)

On scenarios describing the potential for capture of global fossil fuel carbon dioxide emissions by 2050, Lead Author Keywan Riahi clarified that the SPM referred only to capture because there is a lack of literature on the potential for storage.
