CO₂ Capture at Coal-Based Power and Hydrogen Plants

1 May 2014
Capture

In recent years IEAGHG has undertaken a series of studies on the performance and costs of plants incorporating the three leading CO2 capture technologies: post combustion, oxy-combustion and pre-combustion capture. In the time since those studies were undertaken there have been significant technological advances and substantial increases in estimated plant costs. IEAGHG therefore decided to undertake a wholly new study on costs of capture at coal based plants producing the two leading low-carbon energy carriers, namely electricity and hydrogen. This study provides a baseline for possible future studies on plants in other countries, plants using other capture processes and capture in industries other than power and hydrogen generation. The study was carried out for IEAGHG by Foster Wheeler.

IEAGHG 2013 RCSP Peer Review Summary

1 May 2014
Storage

The 2013 international independent expert review of the RCSP had the following aims: 1. To follow up progress in addressing the recommendations of the second review in 2011 of the RCSP Initiative and their Phase III projects. 2. To assess the progress on the individual Phase III projects and consider whether the proposed technical work program for each project achieves the individual projects goals and those of the overall RCSPs. Inherent in this assessment will be the identification of any gaps or modifications that are necessary to the individual work program to address both the projects and the overall RCSP goals. 3. To assess results and key findings from the Phase III tests across the RCSP Initiative as they relate to the DOE/NETL Program goals. 4. To assess the overall technical integration of the RCSP Initiative, address the synergies between the eight Phase III projects and how they complement each other and how collectively they will provide a technical basis for future commercial scale projects in the USA. 5. To assess how the RCSP compares/compliments/contrasts with similar projects underway worldwide and how the information from these projects contributes to an international knowledge base on CO₂ capture and storage

Comparing Different Approaches to Managing CO₂ Storage Resources in Mature CCS Futures

1 April 2014
Storage

This report develops scenarios for CO₂ storage development in the Southern North Sea Basin to compare first-come, first-served and managed approaches to CO₂ storage site licensing. The report describes the benefits and consequences of these broad strategies for the pore space owner and the operator, and considers current approached to managing offshore and onshore storage resources (in a range of jurisdictions). A workshop was held in the early stages of the report process, which helped to evaluate approaches to the management of pore space in different jurisdictions. The following general issues were discussed at the workshop and are looked at further in the report: - The availability of storage capacity - Other uses and users of the pore space - Priorities on different uses in different jurisdictions - Potential routes to wider storage deployment - Technical regulatory challenges for storage in areas of multiple stacked storage opportunities - Risks that may arise from site interactions - Examples of pore space conflict resolution - Strategic initiatives for storage deployment. The report details potential subsurface interactions, UK policy for CO₂ storage development (including a UK Southern North Sea case study), potential interactions between two case studies in the Southern North Sea, CO₂ storage permitting in the Netherlands, CO₂ storage in Australia, the role of CO₂ enhanced oil recovery (EOR) in Texas, USA and managing the pore space in Alberta, Canada.

Evaluation and analysis of the performance of dehydration units for CO₂ capture

1 April 2014
Capture
Transport

The purpose of the study is to examine the characteristics of the various dehydration processes and the way they can be best integrated into the CCS system. Moisture in CO2 can lead to corrosion and hydrate formation. It is necessary to dehydrate CO2 streams prior to transporting the product in carbon steel pipelines. Several different types of CO2 capture processes exist. The type selected for use is dependent upon the basic type of combustion process in operation, e.g. coal or natural gas. The CO2 produced by the various combustion and associated capture processes is of different quality, containing different inerts and impurities, with varying compositions and conditions. The dehydration process can be significantly affected by these differences; it was therefore necessary to consider the different types of capture process separately within this study.

Evaluation of Reclaimer Sludge Disposal from CO₂ PCC Process

1 March 2014
Capture

In this study different solvent reclaiming technologies were evaluated for two reference power plants: Supercritical Pulverised Coal (SCPC) and Natural Gas Combined Cycle (NGCC) at their respective gross power outputs (900 and 810 MWe, respectively). A low sulphur Australian coal was used for SCPC case. A selective catalytic removal (SCR) unit is assumed upstream of the CO₂ capture unit for both the coal and natural gas power plants. In addition a wet flue gas desulfurization (FGD) unit and a sodium hydroxide polishing unit , is located upstream of the CO₂ capture unit in the coal-fired power plant thus reducing the SOx concentration to 10 ppmv or less .

IEAGHG OPEC Report of Workshop on CCS and CDM

1 December 2013
Policy & Regulation

This report outlines the discussions and outcomes from a workshop jointly held by the IEA Greenhouse Gas R&D implementing agreement (IEAGHG) and the Organisation of Petroleum Exporting Countries (OPEC) on the topic of “Carbon Dioxide Capture and Storage in the UN Clean Development Mechanism”. The workshop was the latest in a series of activities by IEAGHG in supporting CCS in the CDM. The objective of the workshop was to share knowledge amongst IEAGHG technical experts and OPEC secretariat and member country delegates, and enhance the understanding amongst all participants of the issues, challenges and approaches to developing CCS projects under the UNs clean development mechanism (CDM) with a focus on OPEC member countries

The study focuses on the following tasks: 1. Review current practice in energy efficiency improvement and fuel and clinker substitution practices in relation to reduction of CO₂ emissions in the cement sector. 2. Engage with key stakeholders with the aim of identifying the key barriers to the demonstration of CCS in the cement sector. 3. Review the current state of development of potential CCS technologies evaluated for the cement industry, particularly oxyfuel and post-combustion capture and review current CCS activities initiated and led by the cement industry. 4. Review policy and government initiatives to support the application of CCS to the cement sector

Methodologies and Technologies for Mitigation of Undesired CO₂ Migration in the Subsurface

1 December 2013
Storage

The driver behind this study is to develop a report built on the on the previous IEAGHG report on methods of leakage mitigation (2007/11). The proposed study should focus on current mitigation and remediation methods that may be applied or considered in site specific conditions in the event of unpredicted CO₂ migration. Each geological storage site will have an adaptive site specific monitoring plan, based on a risk assessment. Detection of a significant irregularity may involve supplementing the monitoring program, in order to detect a possible leak and if necessary engaging mitigation measures

Summary report of the IEAGHG Modelling Network and the Risk Management Network Meeting

1 November 2013
Event Proceedings
Storage

The three day event consisted of a day dedicated to modelling applications; a second day covering a variety of risk management issues and a final day where topics involving both topics were discussed. The meeting was preceded by visits to the SINTEF research facility in Trondheim and the CO2 pipeline test facility at the Statoil Rotvoll site. During the visit to SINTEFF delegates were shown lab-scale development of new solvents for CO2 capture and an oxy-fuel combustion test rig.
