3rd High Temperature Solid Looping Network Meeting

1 December 2011
Capture
Event Proceedings

The third meeting of the IEAGHG high temperature solid looping network was held from 29th August to 1st September at the Technical University of Vienna. It was held in parallel with a meeting of the IEA Fluidised Bed Combustion implementing agreement and the International Conference on Polygeneration. This gave the 108 delegates who attended the network meeting the opportunity to meet with those engaged in these other related areas. For this meeting a considerable effort was made to attract members of the Chemical Looping Combustion (CLC) research community which has been less represented at past meetings where calcium oxide looping (CaL) cycles for CO2 capture have tended to dominate. This should be a useful change as both processes use similar dual fluidised bed hardware and there is also emergence of hybrid schemes employing both types of reaction. Also several of the larger test facilities are now set up to test both CLC and CaL processes using the same equipment.

Addressing SO2/SO3/Hg/Corrosion Issues in Oxyfuel Combustion Boiler and Flue Gas Processing Units

1 December 2011
Capture

The workshop consisted of two full days, with 3 keynote addresses presented by Prof. Terry Wall (Newcastle University), John Pavlish (EERC) and Prof. Axel Kranzmann (BAM) which review the current understanding on the fate of sulphur and Hg, and corrosion issues during oxyfuel combustion. The keynote addresses were followed by 24 presentations covering the following topics:   <ul> <li>Fundamental research on the fate of sulphur – measurement techniques and discussion on sulphur balance</li> <li>Fundamental research on corrosion issues in high and low temperature regime during oxyfuel boiler operation.</li> <li>Fundamental research on corrosion and ash deposition during oxyfuel combustion</li> <li>Fundamental research on performance of the flue gas processing units in control of NOx, SOx and Hg.</li> <li>Large scale pilot testing experience</li> </ul>

The 7th IEAGHG Monitoring Network Meeting

1 November 2011
Event Proceedings
Storage

The theme for this year’s meeting centred on the 3 criteria for transfer of responsibility in the EU directive: Actual behaviour of the injected CO₂ conforms with the modelled behaviour; No detectable leakage; Storage site is evolving towards a situation of long-term stability While the directive is European, the aims are applicable and necessary to all worldwide storage projects. There is no information yet from experience for the 3rd point, which also derives from the first two, so the focus was on the first 2 aims.

WHWL from Operational CCS Demo’s, Phase 1B

1 October 2011
Industry Insights

In 2009, the IEA Greenhouse Gas R&D Programme (IEAGHG) carried out an assessment of learning that is being provided by operational, large-scale, pilot, demonstration and commercial CCS projects around the world. This was undertaken by questionnaires and analysis of the responses and a report was published, presenting the results. Phase 1b was intended to be an addendum to the original report, gaining further information from projects on more specific topics within the subjects of well injectivity, regulation and public communication. In Phase 1b, twelve projects responded out of the twenty nine that were contacted. IEAGHG received 7 responses on well injectivity, 10 on regulation and 8 on public communication.

Global Storage Resources Gap Analysis for Policy Makers

1 October 2011
Policy & Regulation
Storage

The IEA Greenhouse Gas R&D Programme (IEAGHG), on behalf of the Global CCS Institute, commissioned Geogreen to undertake a study reviewing the current global portfolio of operational and announced CO2 geological storage projects, in the context of key CCS deployment targets for 2020: 20 operational sites stipulated by the G8; and 100 operational sites as described in the 2009 IEA CCS Roadmap ‘Blue’ scenario (limiting atmospheric CO2 concentrations to 450ppm). The Geogreen study included detailed modelling of the timescales and resources required for storage sites to achieve bankable status, whereby final investment decisions can be made in advance of site construction, commissioning and operations. Building on this analysis, the study showed that the current CCS project portfolio could allow the G8 target to be reached provided that adequate resources are made available for a large proportion of the proposed projects and that storage associated with CO₂-EOR can be included.

Potential Impacts on Groundwater Resources of Geological Storage

1 October 2011
Storage

The study, comprising a literature review and desk-based assessment, aimed to produce a ‘high level’ overview of potential impacts on groundwater resources from storage operations, concentrating on DSF storage across a range of typical regional settings. The study also highlighted the current state of knowledge and/or gaps, recommending further research priorities where appropriate.

Combined Modelling Wellbore Integrity Network Meeting

1 October 2011
Event Proceedings
Storage

This combined meeting of the IEAGHG Modelling and Wellbore Integrity networks was held from the 27th to the 29th of April 2011, in Perth, Australia, hosted by Curtin University and the University of Western Australia and sponsored by Shell, Chevron, Curtin University, the University of Western Australia and the Government of Western Australia Department of Mines and Petroleum. Seventy five delegates attended the meeting, representing 9 different countries. The three day event looked at the complexity of models, real projects (local and international), geomechanics and wellbore integrity, followed by a field visit to the site of the planned Collie Southwest CO₂ Hub.

Rotating Equipment for Carbon Dioxide Capture and Storage

1 September 2011
Capture

The work was divided into two stages. The first part was to define the process requirements for the compression for typical coal fired, pre, post and oxy-combustion processes as well as for a gas fired post combustion process. Thereafter a number of optimisations of the integration of the compression system with the rest of the process were examined. In the second part selected manufacturers of CO2 compressors were asked to provide general information on their products and also to make selections and indicate budget prices for compressors to perform the 4 specific sets of compression process requirement. Two novel compression concepts were also reviewed, the most revolutionary being the supersonic compression technology being developed by Ramgen, the other being the use of a low pressure axial flow compressor for the first stage of compression. In addition a novel method to use heat of compression for regeneration of mole sieve dryers was investigated

Feasibility of Monitoring Tools

1 September 2011
Storage

This report sets out to identify and evaluate appropriate monitoring tools for substances mobilised by the actions/reactions caused by CO2 injection during CCS operations and includes a brief description of the types of physical, chemical and biological parameters that might be affected. Monitoring these is important for verifying predicted migration pathways and characterising changes in the physical and chemical properties of associated sedimentary formations and groundwater. Understanding these processes and mapping their distribution aids in the identification of potential monitoring tools and facilitates an assessment of their utility in a particular monitoring domain. Matching the appropriate monitoring tool with the monitoring environment is therefore critical to designing an effective monitoring and verification program
