Co-Production of Hydrogen and Electricity by Coal Gasification with CO₂ Capture

1 September 2007
Capture

The primary purpose of this study is the evaluation of the technologies and the process alternatives that can be used in these complex power and hydrogen generation schemes to optimise efficiency and capital cost and reduce, at the same time, emissions to the atmosphere.Use of hydrogen storage is considered to match the hydrogen demand.

Potential Impacts of Leaks from Onshore CO₂ Storage Projects on Terrestrial Ecosystems

1 July 2007
Storage

The aim of this study was to assess the extent of information currently available on the effects of CO₂ seepage on on-shore ecosystems. The objective of the study was to assess what gaps in knowledge exist and what further research needs to be commissioned to address these gaps. The need for this study was first identified by the International Research Network on Risk Assessment in 2005 (for further information, please see www.co2captureandstorage.info). The study was aimed to complement a broader study that was underway that assessed the current Environmental Impact Assessment (EIA) and Strategic Environmental Impact Assessment frameworks for use with CCS . One of the gaps identified by this study was the need for further research on the environmental impacts of CO₂ on on-shore environments.

CO₂ Capture from Medium Scale Combustion Installations

1 July 2007
Capture

The study assesses the costs and performance of medium-scale CO₂ capture technologies The focus is on CO₂ capture from medium-scale power generation systems, from medium-scale systems for industrial heat production and from medium-scale combined heat and power systems. Other industrial processes which produce CO₂, such as cement, metallurgical and petrochemical processes are not considered in this study With respect to the size, we focus on novel technologies which will become available on the longer term, because it is expected that CO₂ is only likely to be captured from medium-scale sources when most large-scale capture opportunities have been exhausted. An exception is the MEA scrubbing technology which is currently used in industrial applications at a scale of 50 to 400 kt per year. The study only considers new systems and does not consider retrofit systems.

International Network for CO₂ Capture: Report on 10th Workshop

1 July 2007
Capture
Event Proceedings

This report contains presentations on a variety of developments including updates on amines, use of ammonia as a solvent, a process for combining CO₂ and SO2 capture in one unit, a new solvent which facilitates phase separation and so reduces regeneration heat loads, and a set of reports on activities in different countries etc.

Expert Workshop on Financing Carbon Capture and Storage: Barriers and Solutions

1 July 2007
Costs of CCUS
Event Proceedings

The main purpose of the conference was to provide a clearer picture of the options available to finance CCS projects and to increase the involvement of experts from the financial sector and to discuss financial instruments with industry and Government representatives. 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.

Post Combustion Carbon Capture from Coal Fired Plants – Solvent Scrubbing

1 July 2007
Capture

The potential use of solvents for carbon dioxide capture from the flue gas from coal fired power plants is reviewed. After an introduction to solvent absorption of CO₂, the use of alkanolamine solvents, particularly monoethanaloamine (MEA) is considered. The degradation of solvents in the flue gas environment and the consequent corrosion problems associated with the degradation products is then examined. The energy consumption for regeneration of the solvents is a key feature in determining the overall costs of solvent scrubbing. There is considerable research on alternative solvents to MEA which have higher capacity for CO₂ capture and lower energy consumption among other attributes. The design of the absorption contactors which facilitate the contact and interaction of the gas and liquid phases can also contribute to lowering the energy consumption of the overall process. Techno-economic studies, process modelling and simulation are also reviewed. Some details of existing demonstration and pilot plants and current national and international R&D programmes are given. Finally, the potential environmental aspects of the solvent scrubbing processes are briefly examined.

3rd Monitoring Network Meeting Report

1 June 2007
Event Proceedings
Storage

The third meeting of the monitoring and verification network met in Melbourne, Australia over 3 days in October and November 2006. The meeting’s objective was to provide an integrated set of monitoring and verification (M&V) guidelines to encourage further public, regulatory and technical community discussion for wide scale deployment of CCS technology. The objectives were realised by addressing the questions: What is the framework of a Monitoring, Evaluation, Reporting and Verification (MERV) protocol for wide scale CCS deployment? How do we provide assurance of storage integrity through well, seal and containment monitoring technology? The meeting brought together national and international government regulatory agencies, non-government organisations and Monitoring and Verification (M&V) technical communities in an intensive series of workshops. It was followed by a field visit by train to the site of the CO₂CRC Otway Basin Pilot Project (OBPP) in South West Victoria.

CO₂ Capture Ready Power Plants

1 May 2007
Capture

The purpose of this study is to review the technical options that may be available to retrofit a capture technology to the various configurations of power plants that may be built in coming years and to identify (a) necessary and (b) potentially economically attractive options for pre-investment in those plants to make retrofit economically feasible.

3rd Well Bore Integrity Workshop

1 May 2007
Event Proceedings
Storage

The third meeting specifically aims to demonstrate that research has helped to move the technology towards widespread implementation by identifying and understanding the technical barriers encountered while working to address and neutralise these barriers, and also to provide a platform for dissemination of results, information and observations from field and laboratory experiments / measurements. The meeting will also aim to determine what next steps are needed in order to progress the technology even further, into the arena of large-scale demonstration projects.

ERM - Carbon Dioxide Capture and Storage in the clean development mechanism

1 April 2007
Industry Insights
Policy & Regulation

In September 2005 project design documents and methodologies for two carbon dioxide capture and storage projects under the Clean Development Mechanism were submitted for approval. The CDM Executive Board were unable to agree how CCS projects should be handled and sought advice from COP/MOP. This initiated a process of wider consultation. The IEA Greenhouse Gas R&D Programme sounded out its members and interested organisations to determine the level of interest in developing CCS projects under the CDM and found it to be sufficient to warrant organizing a workshop. At this first workshop, held in London in April 2006, the main issues which needed to be addressed when formulating a methodology and preparing a Project Design Document for such projects were discussed in order to determine whether a common approach was possible. Several organizations indicated that they were contemplating the possibility of undertaking CCS projects and that in some cases these might be in countries eligible for hosting CDM projects. Furthermore there was a considerable degree of consensus on how the main issues surrounding monitoring and storage site integrity could be handled.

Environmental Assessment for CO₂ Capture and Storage

1 March 2007
Capture
Storage

This report examines the frameworks for Environmental Impact assessment in use around the world and how adequate they will be for application to CCS projects. It also reviews the gaps in the knowledge which will be required to carry out effective assessments and projects future trends in the scope and application of EIA. Requirements for an internationally applicable framework for CCS projects are outlined.
