The meeting continued the progress made at launch network meeting in developing our understanding of the status of risk assessment in its application to CCS and developing the role that risk assessment can play.
The aim of this Network for Oxy-Fuel Combustion is to provide an international forum for organisations with interest in the development of Oxy-Fuel Combustion Technology to discuss various issues relevant to the development of the technology.
The purpose of the network is to bring together the key groups working on risk assessment for CO2 storage from around the world and to address what the regulators are expecting in regard to CCS assurance and whether risk assessment can provide the answers they require. This report provides a summary of the third risk assessment workshop hosted by Imperial College in London, UK between the 15th and 16th August 2007.
This is the 4th meeting of the IEA Greenhouse Gas R&D Programme (IEA GHG) Monitoring Network. Since the inception of the Monitoring Network a significant amount of work has been done in this field. There are now a great number of very elaborate CCS demonstration projects occurring worldwide with each one developing and testing new monitoring techniques. While this is happening there is also a great drive from many Governments to put in place the regulations needed to properly licence and supervise CCS activities. This meeting hoped to review where we are with both aspects of CCS and identify what questions still need to be answered.
The main purpose of the conference was to provide a clearer picture of the options available to finance CCS projects in North America and to increase the involvement of experts from the financial sector in discussion about possible financial instrument options for CCS. The ultimate outcome of this work will be to identify, encourage and develop world-wide collaboration and practical development of financial mechanisms to accelerate the progression of CCS projects from R&D to commercial reality. The objectives of the meeting were to explore the options of: <!-- wp:acf/columns {"name":"acf/columns","data":{"padding_top":"1","_padding_top":"field_columns_fields_padding_top","padding_bottom":"1","_padding_bottom":"field_columns_fields_padding_bottom","margin_top":"0","_margin_top":"field_columns_fields_margin_top","margin_bottom":"0","_margin_bottom":"field_columns_fields_margin_bottom"},"mode":"preview"} --> <!-- wp:acf/column-content {"name":"acf/column-content","mode":"preview"} --> <!-- wp:list --><ul> <!-- wp:list-item --><!-- wp:list-item --><li>Identifying key drivers on financing CCS projects in North America by the financial sector.</li><!-- /wp:list-item --><!-- /wp:list-item --> <!-- wp:list-item --><!-- wp:list-item --><li>Contributing to building financial mechanisms for deployment of CCS projects</li><!-- /wp:list-item --><!-- /wp:list-item --> <!-- wp:list-item --><!-- wp:list-item --><li>Gaining access to financial information relevant for all major stakeholders such as industry, insurance companies, Government and investors in CCS projects</li><!-- /wp:list-item --><!-- /wp:list-item --> <!-- wp:list-item --><!-- wp:list-item --><li>Use of futures, derivatives and insurance markets to reduce financial risks of CCS deployment</li><!-- /wp:list-item --><!-- /wp:list-item --> <!-- wp:list-item --><!-- wp:list-item --><li>Improving the awareness of the status of CCS technology for the financial community.</li><!-- /wp:list-item --><!-- /wp:list-item --> <!-- wp:list-item --><!-- wp:list-item --><li>Use of insurance to address the financial risks of CCS demonstration plants</li><!-- /wp:list-item --><!-- /wp:list-item --> </ul><!-- /wp:list --> <!-- /wp:acf/column-content --> <!-- /wp:acf/columns -->
This workshop was the eleventh in a series to discuss co-operation in development of MEA and other solvents and associated techniques to capture CO2 from power plant flue gases. The previous events were, in Gaithersburg, Calgary, Apeldoorn, Kyoto, Pittsburgh, Trondheim, Vancouver, Austin, Copenhagen, and Lyon
The broad aims of the network remain unchanged, and they are: To provide confidence to all stakeholders that the mechanisms involved with maintaining wellbores are understood. That the safety of storage, specifically in relation to wellbores, can be ensured because the risks can be identified and minimised. That wellbores can be monitored for early signs of leakage and remediated as necessary. The meeting also had some specific aims identified in the conclusions from the 3rd meeting, and these included: Investigating the contrast between field and lab results. Updating the advances in technologies and understanding, as was seen between the 2nd and 3rd meetings. Continued investigation of the advancements made in the modelling of wellbores and the reactions between CO2 and wellbore materials.
This report presents an overview of the workshop and summarises the current status of development of oxy-fuel combustion. The presentations and discussions at the workshop covered a wide range of topics looking at; on-going studies and experimental results, modelling studies, new developments in oxygen production and CO2 processing, and identification of various issues relevant to the demonstration of oxy-fuel combustion technology.
The agenda was structured in accordance with the 3 criteria with sessions on review of performance monitoring tools, data integration and demonstrating monitoring data conforms with predictive modelling, developing protocols and strategies to form a monitoring plan and monitoring of the outer envelope – demonstrating no leakage. There was also a discussion session on CCS in the CDM – what modelling is required for monitoring and a session on updates and permanent Installations; current and future activities. The meeting ended with a review of the main learnings taken from the meeting.
The meeting was held over 3 days, and covered views of both regulators and industry, and the presentations covered impacts of leaks in both terrestrial and marine environments, and also extensively covered the experience of various research bodies and projects from Europe and the USA. The closing session included an open discussion to determine the needs of the different groups likely to be involved in a storage project, from regulators, industry, researchers and the general public.
The concept of this workshop was previously proposed to the IEA Greenhouse Gas R&D Programme (IEA GHG) by BRGM and Schlumberger, and following the approval of the workshop in principle, discussion was initiated in June 2008 at the IEA GHG Joint Network Meeting in New York. The suggestion was that CO2 geological modelling for Carbon Dioxide Capture and Storage (CCS) was an important topic not being adequately dealt with by the existing storage based research networks. Further discussions by these network groups concluded that this was indeed a gap, and that an initial workshop should be held to determine the viability of forming a separate network dealing solely with geological storage modelling.
The IEA GHG Wellbore Integrity Network has been running for 5 years now, and the meeting in 2009 was held in Calgary, Canada. The attendance for the meeting covered the usual mix of industry, academia, research and regulators, but there was a noted increase in attendance from industrial companies. This was demonstrative of the local area that the meeting was held in, with a large number of oil companies working in the surrounding province. This increased industry representation moved the discussion sessions to areas previously not addressed, or only addressed in brief outline, and this is indicative of the progress of the meeting and its continued worth. A possibility for the future of the network will be an alteration in its role, from pure research into wellbore integrity, materials and abandonment procedures, to one of education of industrial operators, and the broaching of the gap between experience gained from the oil and gas industry, and the needs and demands of regulations relating to CO<sub>2</sub> Capture and Storage (CCS) operations.
