Costs of CCUS
Event Proceedings

IEAGHG’s 8th CCS Cost Network Workshop, hosted by Bechtel at their Energy Headquarters in Houston, the so-called Energy Capital of the World, took place on March 5–6, 2025. This invitation-only, in-person gathering convened around 50 leading experts from industry and academia, fostering a highly interactive forum for in-depth discussions on advancing real-world cost estimation across the CCS value chain. The workshop was opened with welcoming remarks from Bechtel’s Bill Elliot, Operations Manager, ET, and George Whittaker, CCUS Operations Manager, which set the scene for a workshop focused on sharing expertise, challenging assumptions, and identifying practical pathways to lower CCS costs.

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.

Technical Review

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.

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.

Risk Management Network Meeting Report

29 September 2023
Event Proceedings
Storage

The Risk Management Network meeting was held as an in-person event with a particular focus on the risk of wells (particularly legacy wells) in a CCS project, looking at the topic from basin scale through to detailed characterisation of well materials and monitoring. Attended by over 75 delegates from 15 countries, the two day meeting was held at Heriot-Watt University in Edinburgh, UK. It was kicked off by a welcome reception in the Lyell Centre (home to both BGS and the Institute for GeoEnergy Engineering) and was followed by a field excursion to explore the geological history of Arthur’s Seat in Edinburgh and a tour of a very new distillery located in an old train station within stone’s throw of Holyrood Park.
