What Have We Learned from CCS Demonstrations

Publication Overview

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:

Publication Summary

From the initial analysis that has been performed a number of key learning points have been identified that warrant further examination; These are points that will be kept in consideration during further analysis and could be explored further through additional questionnaires or correspondence with the project operators; These include:

• Effectiveness of various monitoring techniques
• Injectivity – prediction, restoration and enhancement
• Design to avoid hydrate formation
• Performance of materials in CO₂ environments
• Scaling up capture train size
• Wells – designing, placing, and monitoring cementation
