Capturing the world’s thinking around carbon emissions

IEAGHG is at the forefront of CCS research. We advance technology that reduces carbon emissions and accelerates the deployment of CCS projects by improving processes, reducing costs, and overcoming barriers. Established in 1991, we were the first international organisation focussed on CCS, and played key roles in many CCS breakthroughs, and continue to do so today.

We are a technology collaboration programme (TCP) of the International Energy Agency. Together, the TCPs mission is to work with governments and industries around the world to advance the research, development and commercialisation of energy technologies.

Artificial Intelligence in Carbon Capture, Utilisation, and Storage 2025 Workshop

30 October 2025
Event Proceedings
Industry Insights

The IEAGHG AI in CCUS Workshop, held virtually on 29–30 April 2025, was convened to foster a deeper understanding of the role artificial intelligence (AI) can play in advancing carbon capture, utilisation and storage (CCUS).

Technical Report

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.

Proceedings of the CCS Cost Network 2025 Workshop

1 October 2025
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.

Market Models for CCUS/CDR – A Global Screening

10 September 2025
Industry Insights
Policy & Regulation

This report provides a key pillar to interested parties including policy makers, regulators, and the technical carbon capture, utilisation and storage (CCUS) / carbon dioxide removal (CDR) community on potential successful market strategies, including their pros and cons and their suitability for dierent economic and political realities, which may lead to the fast development of an efficient, safe, and accepted CCUS/CDR market sector.

CO2 Flow Metering Technologies

4 September 2025
Policy & Regulation
Transport

The main objective of this study is to raise awareness of the relevance, state of the art, challenges and opportunities of flow metering for carbon capture, utilisation and storage (CCUS). Flow metering of CO2 streams will be critical in supporting trade, protecting consumers, ensuring confidence, facilitating taxation, and meeting CO2 reduction goals and treaty obligations.

Technical Report

The Value of Direct Air Carbon Capture and Storage (DACCS)

4 September 2025
Capture

The aim of this study is to evaluate the value of direct air capture and storage (DACCS) in the energy transition (down to the regional level), accounting for key factors, including carbon removal eiciency, timeliness, durability, land footprint and techno-economic performance.

Technical Report

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.

Technical Report

A Critical Study on Waste to Low Carbon (CCS-abated) Hydrogen

23 April 2025
Utilisation

This study presents a systematic review of waste-to-hydrogen (WtH) technologies and conducts analysis of the technological, economical, and environmental aspects of the most promising waste-to-low carbon hydrogen technologies for near-term commercial deployment.

Technical Report

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.
