Publication Overview

This 5th Workshop on Offshore Geologic CO2 Storage covered multiple subjects, including: summary of multiple CCS projects worldwide, subsurface considerations for depleted hydrocarbon fields, containment/ pressure management, and saline formations to store CO2, as well as considerations on regulating offshore CCS, monitoring offshore CCS projects, CO2 shipping and infrastructure for CO2. Importantly, this is the first hybrid in-person and virtual workshop, which represents a milestone to bring this knowledge sharing to multiple people interested on CCS worldwide

Publication Summary

The following conclusions and recommendations were agreed by the workshop delegates.

Conclusions from this workshop:

  • The growing number of projects since last workshop. We are in a momentum.
  • The range of projects in design and coverage of emissions. Good for others to learn from.
  • Some project planning to use shipping for transport and/or injection.
  • Good participation by regulators in this workshop, i.e., BSSE, BOEM.
  • New industry players coming in, with new interest and ideas.
  • Re-use of infrastructure is complex, technically and legally. Good examples of the details needed from some projects.
  • Can we co-locate activities, i.e., CCS projects with wind farms? It can be complex and not always possible.
  • Good display on the use of environmental monitoring research outputs for real projects (STEMM-CCS and ECO₂ to Northern Lights, Greensand, Northern Endurance Partnership).
  • Northern Lights environmental monitoring plan, ‘down-selecting’ from R&D projects, so as to be ‘fit for purpose’

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.

  • 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.

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.

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.

7th Cost Network Proceedings

  • 1 November 2023
  • 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.
