4th CCS Cost Network Meeting

1 August 2016
Costs of CCUS
Event Proceedings

The purpose of the workshop is to share and discuss the most currently available information on the cost of carbon capture and storage (CCS) in electric utility and other industrial applications, as well as the current outlook for future CCS costs and deployment. The workshop also seeks to identify key issues or topics related to CCS costs that merit further discussion and study.

2014-TR4 Emerging Capture Technologies

1 December 2014
Capture
Costs of CCUS

This Technical Review gives an interim overview of research and development aimed at improving and reducing the cost of commercial scale carbon dioxide capture in the power and process industries. It considers technologies principally applicable in post-combustion capture, pre-combustion capture, oxy-combustion capture and finally systems with circulating solids; in that order, which is more or less in line with the current maturity of each approach. It then goes on to consider applications in iron and steel and cement production and oil refining. IEAGHG’s normal practice is for its reports to be sent to external reviewers and for the reviewers’ comments to be taken into account prior to publication. This Technical Review is an interim report which has not yet gone through this process. An IEAGHG Report which has been subject to external review will be published in due course.

Techno-Economic Evaluation of Different Post-Combustion CO2 Capture Process Flow Sheet Modifications

1 August 2014
Capture
Costs of CCUS

This study evaluated different post combustion capture process modifications for SCPC and NGCC power plant. The study also evaluated the current state of process design improvements such as absorber intercooling, operation at higher stripper pressure and an advanced level of waste heat integration for the SCPC case. In order to identify the effect of future improvements in the solvent; a generic improved amine based solvent ‘Solvent 2020 was considered. Regarding to the different process modifications, matrix stripping was found to be having the highest efficiency penalty due to the increased energy requirement by compressors. Also the cost of electricity and cost of CO2 avoided for this modification was found to be higher compared to other process modifications.

Iron and Steel CCS Study (Techno-Economics Integrated Steel Mill)

1 July 2013
Capture
Costs of CCUS

The primary goal of this project is to establish a methodology to evaluate the cost of steel production when deploying CO₂ capture technology in an integrated steel mill. The objectives of this study were: To specify a “REFERENCE” steel mill typical to Western European configuration; and assess the techno-economic performance of the integrated steel mill without and with CO₂ capture. To evaluate the techno-economic performance, the breakdown of the CO₂ emissions; and estimating the CO₂ avoidance cost of the following cases: o Case 1: An integrated steel mill typical to Western Europe as the base case. o Case 2: Post-Combustion CO₂ capture using conventional MEA at two different levels of CO₂ capture rate (End of Pipe Cases or EOP) o Case 3: An Oxygen Blown Blast Furnace (OBF) with top gas recycle and the use of MDEA/Pz as solvent for CO₂ capture

Toward a Commons Method of Cost Estimation for CO₂ Capture and Storage at Fossil Fuel Power Plants

1 March 2013
Costs of CCUS
Industry Insights

To address the current state of CCS costs, a workshop was convened in March 2011 at which an international group of experts from industrial firms, government agencies, universities, and environmen tal organizations met to share information and perspectives on CCS costs for electric power plants [2]. A major conclusion of that work shop was that there are significant differences and inconsistencies in the way CCS costs are currently calculated and reported by various authors and organizations. As a consequence, there is a significant degree of confusion, misunderstanding, and mis-representation of CCS costs in the information now available publicly. These incon sistencies hamper the ability to correctly and systematically com pare the cost of different carbon capture options. They also distort comparisons between CCS and other greenhouse gas reduction measures—with potential consequences for both technology and policy developments.

Financial Mechanisms for Long-Term CO₂ Storage Liabilities

1 November 2012
Costs of CCUS
Storage

The study aimed to review current laws and emerging CCS specific regulations, in different regions of the world and under different legal frameworks, concentrating on long-term liability aspects. The primary work of the study was to investigate and assess the various potential financial mechanisms for supporting CO₂ liability, including an assessment of their applicability and practicality to all parties concerned, and provide recommendations based on the findings. As well as discussion on important issues such as when and how transfer of liability to the government should occur, and what these liabilities could be, the study focuses primarily on how this liability can be supported.

Techno-Economic Evaluation of Biomass Fired or Co-Fired Power Plant with Post-Combustion CO₂ Capture

1 October 2009
Capture
Costs of CCUS

The study aimed to investigate options and evaluate the techno-economic performance of a biomass fired, or coal co-fired with biomass, power plant based on current state of the art boiler and steam generation equipment incorporating CO₂ capture technology. It is expected that the study should provide the performance of the plant assuming the need to capture at least 90% of the total CO₂ emissions. Currently, the state of the art largest standalone biomass fired combustion power plant (i.e. between 100 to 250 MWe net) offered commercially is based on circulating fluidized bed (CFB) technology. In the mid-range (i.e. between 30 to 90MWe net), the commercially offered state of the art technology would be based on a bubbling bed fluidized bed (BFB) technology. For less than 50MWe net, a stoker fired (fixed bed) system is still considered competitive compared to any fluidized bed technology. For direct co firing of biomass and coal, the technical operating limit of co-firing biomass is about 10-20% of the total thermal input.

Criteria for Technical and Economic Assessment with Low CO₂ Emissions

1 May 2009
Capture
Costs of CCUS

The IEA Greenhouse Gas R&D Programme (IEA GHG) undertakes studies to assess technologies for abatement of greenhouse gas emissions. IEA GHG has concentrated on CO₂ Capture and Storage (CCS) applied to power generation but it has also assessed CCS in other industries and will compare the relative merits of CCS and alternative greenhouse gas abatement options. Soon after IEA GHG started operation in 1991 it produced a set of standard technical and economic criteria for assessment of power plants with capture to ensure that its studies are undertaken on a consistent basis, as far as possible. These criteria have continued to be used since then, with some minor modifications.

Upgraded calculator for CO₂ pipeline systems

1 March 2009
Costs of CCUS
Transport

A contract to develop and upgrade the original Woodhill program and the network program was awarded to Gastec UK/AMEC who had already produced the new network design program. After obtaining the original code from Woodhill-Frontier options were examined and it was felt that as both programs were Excel-based it would be simplest to amalgamate them into one program using the original Woodhill interface where possible.The possibility of adding a graphical map-based interface for the distributed collection network was investigated as an additional option but although possible the necessary licence for commercial use was found to be too costly. It was on this basis that GastecUK/AMEC proceeded with the development of the upgraded calculator.

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: Identifying key drivers on financing CCS projects in North America by the financial sector. Contributing to building financial mechanisms for deployment of CCS projects Gaining access to financial information relevant for all major stakeholders such as industry, insurance companies, Government and investors in CCS projects Use of futures, derivatives and insurance markets to reduce financial risks of CCS deployment Improving the awareness of the status of CCS technology for the financial community. Use of insurance to address the financial risks of CCS demonstration plants
