Citation: IEAGHG, "Wellbore Integrity Network Summary Report", 2012-01, December 2012.

Publication Overview

The purpose of this report is to describe the Wellbore Integrity Network, summarise past meetings, outline key findings and identify current state of knowledge

Publication Summary

The network meetings have presented detailed information from industrial analogues to storage, especially from the oil and gas industry including North American CO2-EOR and acid gas disposal projects. Statistics on wellbore leakage and failure rates have been presented and discussed, whilst best practice guidelines have been debated. Research over the last 6 years has greatly improved our understanding of processes linked to potential alteration and degradation of wellbore materials, especially cements. Much of the relevant research is included within presentations made at network meetings

Insurance Coverage for CO2 Storage Projects

16 August 2024
Industry Insights
Storage

This report is a focused review of recent developments regarding insurance coverage for carbon dioxide (CO2) geological storage projects. It seeks to address the following: what companies are offering or planning to offer insurance to CO2 storage projects, what is the scope and duration of the coverage offered, and does coverage extend to the transportation of CO2 to the project site? This work and report was prepared by Franz Hiebert.

CO2 Storage Site Catalogue

8 August 2024
Storage

This Technical Review provides an overview of 22 CO2 storage sites from around the world. These include CO2-EOR, commercial scale storage sites and a number of pilot and demonstration storage sites in both depleted hydrocarbon reservoirs and saline reservoirs. Its primary aim is to provide a convenient source of collated information with a specific focus on technical information that are in the public domain.

Monitoring Network Meeting Report

1 December 2023
Event Proceedings
Storage

The IEAGHG Monitoring Network aims to assess new technologies and techniques in the monitoring of CO2 storage, determine the limitations, accuracy and applicability of monitoring techniques, disseminate information from research and pilot storage projects around the world, develop extensive monitoring guidelines for the different sub-categories of geological storage; oil and gas fields, unmineable coal seams, and saline aquifers covering the differing conditions and reservoir properties encountered globally as well as to engage with relevant regulatory bodies.

6th International Workshop on Offshore Geologic CO2 Storage

1 December 2023
Event Proceedings
Storage

The 6th International Workshop on Offshore Geologic CO2 Storage was held in Aberdeen on 13-14 September. Organised with the University of Texas and hosted by the University of Aberdeen. The loca on was very appropriate as we were co-hosted and sponsored by Storegga who leads the Acorn project nearby in Scotland. This project had been recently announced by the UK government as a Track 2 Cluster project. This 6th workshop had 190 delegates (60 in-person and 130 virtual) from 35 countries, with a good mix of industry, researchers and regulators.

Components of CCS Infrastructure – Interim CO2 Holding Options

27 November 2023
Storage
Transport

This work, undertaken on behalf of IEAGHG by TNO and SINTEF, provides an overview of temporary / interim CO2 storage, or ‘holding’, options (also called buffers) and investigates the role of buffer storage and its potential to create flexible and robust carbon capture and storage (CCS) chains. The report looks at current and emerging buffer technologies, conducts simulations to demonstrate the temporary storage required for given flow-rate scenarios and discusses the impact of buffer capacity on transport costs. In the report, the storage requested in the chain for normal operation is presented as " temporary storage" and storage to give buffer capacity is presented as " buffer storage". This report has focussed on buffering at the emitter site. The results of this study will benefit CO2 storage site project developers, operators, financiers and regulators.

Cost Network Proceedings

Costs of CCUS
Event Proceedings

The 7th edition of the IEAGHG CCS Cost Network Workshop was hosted at the University of Groningen, Netherlands, on 12-13 April 2023. The purpose of the workshop was to share and discuss the most current information on the costs of carbon capture and storage (CCS) in various applications, as well as the outlook for future CCS costs and deployment. For the first time, this workshop also included a session on the direct capture of CO2 from the atmosphere. The workshop also sought to identify other key issues or topics related to CCS costs that merit further discussion and study.

Techno-Economic Assessment of Small-Scale Carbon Capture for Industrial and Power Systems

1 March 2024
Capture
Costs of CCUS

This study, undertaken on behalf of IEAGHG by Element Energy (now a part of ERM), explores the role of CCS in decarbonising small-scale industry and power generation applications. While relatively under investigated compared to their larger scale counterparts, reaching net zero will be dependent on successfully addressing the emissions from small-scale facilities. The findings from the study will be of interest to the broader energy community but, in particular, should benefit project developers, the finance community and policymakers.

Clean steel an environmental and technoeconomic outlook of a disruptive technology

1 March 2024
Capture
Costs of CCUS

This study primarily presents a comparative analysis of steelmaking pathways to cost-effectively decarbonise a steel mill, taking a life-cycle perspective on associated environmental impacts. The roll-out of clean steel technologies is envisioned to have a significant implication for support infrastructure. Therefore, a secondary objective of the study is to gain insights into the primary energy and infrastructure implications associated with large-scale deployment of different steel decarbonisation pathways. Clean steel production will likely be more expensive than steel produced today; this poses additional economic strains on steel producers and consumers. Consequently, a third objective is to estimate the price premium that clean steel could command in existing and future markets. Further, this study formulates recommendations for key stakeholders to support the sector and outlines recommendations for further work.

The Role of Indices in Assessing the Maturity of CCUS Technologies and their Readiness for Deployment

1 February 2024
Industry Insights

This study was undertaken on behalf of IEAGHG by Foresight Transitions Ltd. While a technology may be technically mature, it has become increasingly clear that the technology may not necessarily be considered commercially ‘bankable’ by investors. In this study, the potential for an index or indices to provide that confidence was explored. The findings from the study will be of interest to the broader energy community but, in particular, should benefit technology developers, CCUS end users, investors and policymakers.
