Risk Management and Monitoring Networks Combined Meeting Report
- 15 January 2026
- Event Proceedings
- Storage
Two IEAGHG expert networks, the Risk Management Network and the Monitoring Network, held a combined meeting from 27th to 28th August 2025 in The Hague, The Netherlands. Both networks have been convening for 20 years, and this meeting, hosted by Shell at the Shell Centre, represented the 11th Risk Management and the 15th Monitoring meeting.
CO2 Transport and Storage Availability
- 28 November 2025
- Storage
- Transport
The objective of this study is to investigate realistic rates of CO2 Transport and Storage operational availability that may be achievable for future systems, with a focus primarily on pipeline transportation and storage within sedimentary basins (saline aquifers and depleted fields).
CO2 Transport and Storage Cost Review
- 9 October 2025
- Costs of CCUS
- Storage
- Transport
The objective of the study was to review publicly available information on CO2 transport and storage (T&S) costs, to provide insights into how typical cost estimates are built up and to inform on areas of risk. Current information on T&S costs and the need for new or improved data would be explored.
Review of CO2 storage via in-situ mineralisation in mafic-ultramafic rocks
- 22 August 2025
- Storage
This report evaluates progress, barriers, and knowledge gaps, and provides stakeholders, regulators, and investors with a comprehensive summary of current knowledge and understanding of subsurface carbon mineralisation in mafic-ultramafic reservoirs.
Reviewing the implications of unlikely but potential CO2 migration to the surface or shallow subsurface
- 29 January 2025
- Storage
CO2 leakage from geological storage is considered unlikely. However, it is important to understand environmental and health risks to ensure appropriate mitigation and monitoring is established.
7th International Workshop on Offshore Geologic CO2 Storage
- 23 January 2025
- Event Proceedings
- Storage
The 7th International Workshop on Offshore Geologic CO2 storage was held in Port Arthur, TX, on September 17-18th 2025.
Geological Storage of CO₂: Seal Integrity Review
- 10 September 2024
- Storage
This comprehensive seal integrity review, undertaken by CO₂CRC on behalf of IEAGHG, provides a detailed, updated exploration of the critical aspects of seal potential in the context of the geological storage of CO₂.
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.
Managing the transition of depleted oil and gas fields to CO₂ storage
- 12 August 2024
- Policy & Regulation
- Storage
This work provides a careful and thorough exploration of the major issues involved in the transfer of use of a field from hydrocarbon extraction to CO₂ storage, to identify both the pros and cons of such a transition.
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.
