Workshop on Operating Flexibility of Power Plants with CCS

  • 1 January 2010
  • Capture
  • Event Proceedings

This report is a summary of a workshop on the operating flexibility of power plants with CCS that was organised in November 2009 by IEAGHG in collaboration with Imperial College London. Operating flexibility is becoming recognised as an important issue for CCS plants but so far there has been relatively little discussion of the subject.The workshop included presentations by invited speakers followed by discussions sessions. The presentations focussed on electricity systems and CCS operating requirements, and modelling and operating experience of the flexibility of the three main CO<sub>2</sub> capture techniques (pre-combustion, post combustion and oxy-combustion capture) and CO<sub>2</sub> transport and storage.

Corrosion and selection of materials for carbon capture and storage

  • 1 January 2010
  • Capture
  • Storage

The IEA Greenhouse Gas R&D Programme (IEAGHG) has studied many aspects of Carbon Dioxide Capture and Storage (CCS). As part of this programme, the current study investigates the potential corrosion risks in the CCS processes and proposes suitable materials of construction to mitigate those risks. The scope of this study covers all aspects of the CCS systems, including the carbon capture plants, transport of CO₂ and injection wells.

The I EA G reenhouse G as R &D P rogramme ( IEA GHG ) ha s recently co mmissioned the Alberta Research Council in Canada to conduct a review of storage site selection criteria and site ch aracterisation methods in o rder to produce a s ynthesis r eport. Among the va rious elements of the CO₂ capture and storage (CCS) chain, t he stage of storage site selection and characterisation is o f cr itical importance be cause any storage s ite m ust de monstrate that it satisfies three fundamental requirements: 1. capacity to store the intended volume of CO₂ 2. injectivity, to accept/take CO over the lifetime of the operation, 2 3. containment, to en sure t hat C O at the rate that it is supplied from the emitter(s), 2 will n ot m igrate an d/or leak out of t he s torage unit (safety and security of storage). This report reviews the literature on the subject on site selection and characterisation since the publication of the IPCC Special Report on CCS, and provides a synthesis and classification o f criteria.

CO₂ Storage in Depleted Oil Fields

  • 1 December 2009
  • Storage

The study took as its starting point, IEA GHG Report on PH3/23 undertaken in 2000 as its base line data set.  The study was to assess the data within the report and determine whether there was newer data on issues, (e.g. CO<sub>2</sub> use/bbl oil produced in EOR floods) that could be used to revise global estimates.

OPEC-IEA GHG CCS workshop for scientists and professionals in OPEC Member Countries

  • 1 December 2009
  • Event Proceedings
  • Industry Insights

This workshop was proposed to the IEA GHG by OPEC, and the first plan was to hold the workshop in February 2009, in Algeria. Due to difficulties in preparing invitation letters and visas; the workshop was postponed to November 2009. The suggestion was that Carbon Capture and Storage (CCS) was an important topic not being adequately dealt with by OPEC member countries. Therefore, this workshop was planned to introduce scientists and professionals from OPEC member countries with a general overview of the complete CCS chain. In addition, this workshop was considered as a good opportunity for IEA GHG to interact with professionals from these countries, who are involved mainly in the oil and gas sector.   The Ministry of Energy and Mines together with Sonatrach, agreed to host the workshop in Hassi Messaoud, Algeria. An organizing committee was established, with members form IEA GHG, OPEC, the Ministry of Energy and Mines and Sonatrach. The workshop was held from the 16th to 20th of November, 2009 and attracted over 25 delegates from 7 countries.

A Review of the In'tl State of the Art in Risk Assessment Guidelines and Proposed Termimology for Use in CO₂ Geological Storage

  • 1 December 2009
  • Storage

The work carried out included the following key elements: a review of the international terminology and regulations with a focus on public health and engineering systems risk assessment and management; a compilation of generic and specific terminology for risk assessment and management relevant for CO₂ geological storage; a formal report of the methods used, results and conclusions.

5th Meeting of the Monitoring Network

  • 1 November 2009
  • Event Proceedings
  • Storage

This was the 5th meeting of the IEA Greenhouse Gas R&D Programme (IEA GHG) Monitoring Network. Since the inception of the Monitoring Network a significant amount of work has been done in this field. There are now a great number of very elaborate Carbon Capture and Storage (CCS) demonstration projects occurring worldwide with each one developing and testing new monitoring techniques. While this is happening there is also a great drive from many Governments to put in place the regulations needed to properly licence and supervise CCS activities. This meeting hoped to review where we are with both aspects of CCS and identify what questions still need to be answered

What Have We Learned from CCS Demonstrations

  • 1 November 2009
  • Industry Insights
  • Storage

The IEA Greenhouse Gas R&D Programme (IEA GHG) has undertaken an assessment of the learning that is being provided by operational, large-scale, pilot, demonstration and commercial CCS projects around the world. This was undertaken by questionnaire and analysis of the responses. From the analysis of the responses, key themes, learning points and areas for beneficial collaboration are identified. The extent of coverage of projects is summarised in terms of geological properties and monitoring techniques. From this initial analysis, a number of key learning areas have been identified that also warrant further investigation.  These include: <!-- wp:acf/columns {"name":"acf/columns","data":{"padding_top":"1","_padding_top":"field_columns_fields_padding_top","padding_bottom":"1","_padding_bottom":"field_columns_fields_padding_bottom","margin_top":"0","_margin_top":"field_columns_fields_margin_top","margin_bottom":"0","_margin_bottom":"field_columns_fields_margin_bottom"},"mode":"preview"} --> <!-- wp:acf/column-content {"name":"acf/column-content","mode":"preview"} --> <!-- wp:list --><ul> <!-- wp:list-item --><!-- wp:list-item --><li>Effectiveness of various monitoring techniques</li><!-- /wp:list-item --><!-- /wp:list-item --> <!-- wp:list-item --><!-- wp:list-item --><li>Injectivity – prediction, restoration and enhancement</li><!-- /wp:list-item --><!-- /wp:list-item --> <!-- wp:list-item --><!-- wp:list-item --><li>Design to avoid hydrate formation</li><!-- /wp:list-item --><!-- /wp:list-item --> <!-- wp:list-item --><!-- wp:list-item --><li>Performance of materials in CO<sub>2</sub> environments</li><!-- /wp:list-item --><!-- /wp:list-item --> <!-- wp:list-item --><!-- wp:list-item --><li>Scaling up capture train size</li><!-- /wp:list-item --><!-- /wp:list-item --> <!-- wp:list-item --><!-- wp:list-item --><li>Wells – designing, placing, and monitoring cementation</li><!-- /wp:list-item --><!-- /wp:list-item --> </ul><!-- /wp:list --> <!-- /wp:acf/column-content --> <!-- /wp:acf/columns -->

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.
