The inaugural meeting of the Network of National CCUS Centres of Excellence (NNCCE) was held virtually on 30 July 2025, bringing together over 20 representatives from leading CCUS institutions across the Global South.

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).

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.

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.
