The fourth IEA GHG Risk Assessment Network Meeting was held on the 16th—17th April 2009 in Melbourne, Australia, and hosted by CO2CRC. Cliff Kavonic of Victorian Department of Primary Industries gave the official welcome. The Victorian Government was that day publishing a report by Geoscience Victoria on the storage potential in the Gippsland basin in south Victoria. The fifty six attendees enjoyed the discussions based around the six sessions. These were on reports from other initiatives, leakage impacts, combining monitoring with modelling and risk assessment, insurance and risk, risk communication, and updates from real projects.

5th Meeting of the Monitoring Network

1 November 2009
Event Proceedings
Storage

This was the 5th 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 Carbon Capture and Storage (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

OPEC-IEA GHG CCS workshop for scientists and professionals in OPEC Member Countries

1 December 2009
Event Proceedings
Industry Insights

This workshop was proposed to the IEA GHG by OPEC, and the first plan was to hold the workshop in February 2009, in Algeria. Due to difficulties in preparing invitation letters and visas; the workshop was postponed to November 2009. The suggestion was that Carbon Capture and Storage (CCS) was an important topic not being adequately dealt with by OPEC member countries. Therefore, this workshop was planned to introduce scientists and professionals from OPEC member countries with a general overview of the complete CCS chain. In addition, this workshop was considered as a good opportunity for IEA GHG to interact with professionals from these countries, who are involved mainly in the oil and gas sector. The Ministry of Energy and Mines together with Sonatrach, agreed to host the workshop in Hassi Messaoud, Algeria. An organizing committee was established, with members form IEA GHG, OPEC, the Ministry of Energy and Mines and Sonatrach. The workshop was held from the 16th to 20th of November, 2009 and attracted over 25 delegates from 7 countries.

Workshop on Operating Flexibility of Power Plants with CCS

1 January 2010
Capture
Event Proceedings

This report is a summary of a workshop on the operating flexibility of power plants with CCS that was organised in November 2009 by IEAGHG in collaboration with Imperial College London. Operating flexibility is becoming recognised as an important issue for CCS plants but so far there has been relatively little discussion of the subject.The workshop included presentations by invited speakers followed by discussions sessions. The presentations focussed on electricity systems and CCS operating requirements, and modelling and operating experience of the flexibility of the three main CO<sub>2</sub> capture techniques (pre-combustion, post combustion and oxy-combustion capture) and CO<sub>2</sub> transport and storage.

2nd Meeting of the Geological Storage Modelling Network

1 April 2010
Event Proceedings
Storage

The second meeting of the IEAGHG International Research Network on CO2 Geological Storage Modelling was hosted by the University of Utah in Salt Lake City, on February 16th and 17th, 2010. The meeting comprised four technical sessions: Modelling Methodology and Recent Advances, Integrated Roles and Objectives of Modelling, Modelling of Real Storage Projects; Case Studies and International Efforts towards Best Practice and Modelling Protocols. The agenda was designed to provide ample time for discussions between participants, with breakout groups in sessions 1 and 2, and plenary discussions following sessions 3 and 4. Discussions following Session 1 focussed on recent advances in modelling. Current theoretical and laboratory scale research has continued to advance our understanding of the processes which will control the behaviour of stored CO2 in the subsurface and govern potential leakage mechanisms. However, there was a consensus that an increased number of large-scale storage projects are required to provide data with which modelling methods can be calibrated

5th Meeting of the Risk Assessment Network

1 May 2010
Event Proceedings
Storage

The two day workshop was divided into eight sessions, opening with a welcome session and closing with the Outcomes and Recommendations discussion session. Presentations were held over six sessions, covering key topics: Regulatory Requirements, What can Risk Assessment deliver?, Risk Communication, Update from Real Projects, Induced seismicity/Geomechanics, and Long-term Risk Management; with twenty minute presentations on average and a minimum thirty minute facilitated discussion. All the discussion sessions were met with enthusiastic input from all participants, many of which continued into the coffee and lunch breaks, expressing the great interest in the workshop topics, and the importance of such an open forum for advancing knowledge in this topical field.

Event Proceedings
Storage

There are currently several carbon dioxide capture and storage (CCS) projects around the world with extensive monitoring programs. A review and new results for many of these were presented. As this meeting was held in the USA, a session was given to the work being carried out by the US Regional Partnerships (USRPs). This includes projects at various phases, including several at validation phase, planning phase and ongoing development phase. The latter includes the Cranfield site in Mississippi.

Workshop on Environmental Impact of Amine Emissions during Post-Combustion Capture

1 June 2010
Capture
Event Proceedings

The amine post combustion capture technology is based on washing the flue gas with a solvent that captures CO2. Thus, a small fraction of this solvent will be released through the stack together with the cleaned flue gas. This release may cause environmental concerns both directly and indirectly through subsequent solvent degradation into other substances in the atmosphere. There is a clear lack of understanding of the characteristics of the used solvent and their degradation products, which are an additional concern. From the global prospective, it is clear that the activities in relation to this topic are limited and there is a clear need for cooperation and knowledge exchange between the different institutes. Therefore, the “Environmental Impact of Post Combustion Capture” workshop was held, primarily to share information on the environmental effect of using chemical solvents for capturing CO2, associated with conventional combustion based fossil fuel fired power stations

6th Meeting of the Wellbore Integrity Network

1 July 2010
Event Proceedings
Storage

This eclectic mix of representation ensured the discussion sessions remained varied, without bias, and included debate reflecting different viewpoints. The future of the network will be determined over the next couple of years, with a proposal to hold a combined Modelling / Wellbore Integrity Meeting in 2011, and the 2nd Joint Network Meeting in 2012. The outcomes of these meetings will help to shape the future development of the IEAGHG networks as a whole. The format of the meeting allowed for 20 minute presentations with 5 minutes for questions. Each of the three meeting sessions was followed by prolonged discussion sessions where ideas and experiences were discussed by the meeting attendees at a greater level of detail. These discussion sessions are the primary focus of this report, and the presentations are available on the network webpage for reference.
