Gaseous Emissions from Amine Based Post Combustion CO₂ Capture Processes and their deep removal

1 May 2012
Capture

This report evaluates the emission from the PCC technology that uses amine based inhibitor-free solvents, particularly MEA, ammonia and amino acid salt based solvents. It identifies shortcomings in terms of the environmental performance of existing PCC technology. It also evaluates various emission control methods that may be applied to minimise the emissions particularly from MEA and other amine technologies. All these aspects of the study are covered in the four sections of this report. A complete evaluation of environmental impact of the amine based process would involve assessment of all direct discharge of waste material from the process and the fates of these compounds, including chemical transformations that occur after their discharge. However, it is to be noted that only gaseous emissions are evaluated in this report and liquid and solid emissions are considered as beyond the scope of this study.

Emissions of Substances Other than CO₂ from Power Plants with CCS

1 March 2012
Capture

The emissions of CO₂ from power plants equipped with carbon dioxide capture systems are reduced by upwards of 85% compared to equivalent plants without capture. However the full environmental impact of a plant fitted with CO₂ capture will depend also on what changes are induced in emissions of other substances in gaseous, liquid and solid form. Furthermore due to the increase in fuel and chemicals consumption typical for a CCS plant emissions due to the “upstream” and “downstream” processes and particularly those associated with increased fuel use, will also increase. Both these effects need to be taken into account if the technology is to be assessed on a life cycle basis. This study focuses only on the changes which are to be expected in the direct emissions, discharges and solid wastes of substances other than CO₂ from within the boundary of power plants fitted with CO₂ capture

Summary Report of the 6th Risk Assessment Network Workshop

1 March 2012
Event Proceedings
Storage

The three day workshop highlighted the latest international CO₂ storage risk assessment developments, discussing communication and regulatory developments, risk and incident management, potential induced seismicity, monitoring performance, understanding potential groundwater impacts, risk assessment methodologies, key outcomes and identified knowledge gaps which need to be addressed in future research.

Integration of Solar Energy Technologies with CCS

1 March 2012
Capture

This study was undertaken to identify and quantify opportunities for Carbon Capture and Storage (CCS) and renewable energy technologies to be combined in a synergistic way and to identify any options which would tend to leave a permanent legacy for the renewable power generation industry. Several interesting options were studied and the key option of providing renewable thermal energy to compensate for the parasitic losses incurred by post combustion CCS was studied in some detail.

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: Fundamental research on the fate of sulphur – measurement techniques and discussion on sulphur balance Fundamental research on corrosion issues in high and low temperature regime during oxyfuel boiler operation. Fundamental research on corrosion and ash deposition during oxyfuel combustion Fundamental research on performance of the flue gas processing units in control of NOx, SOx and Hg. Large scale pilot testing experience

1 November 2011
Event Proceedings
Public Perception

The two day workshop discussed methodologies and techniques, working in contentious environments, social science CCS research in Japan, learnings from other energy technology research, use of social media, knowledge gaps which need to be addressed in future research and future aims of the IEAGHG Social Research Network (SRN).

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.
