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.

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.
