Capturing the world’s thinking around carbon emissions

The IEA Greenhouse Gas R&D Programme 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.

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.

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.

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.

Technical Report

Analysis of Electrolytic Hydrogen Technologies with a Comparative Perspective on Low-Carbon (CCS-Abated) Hydrogen Pathways

4 December 2024
Utilisation

An evaluation of various electrolytic hydrogen production pathways focusing on their technical, economic, and environmental aspects and comparing these with hydrogen production routes that involve fossil fuel with carbon capture and storage (CCS) abatement.

Technical Report

The Role of Low Emissions Dispatchable Power in the Lowest Cost Net Zero System

20 September 2024
Costs of CCUS

This study explores the interdependencies of different power generation technologies in a highly decarbonised future.

Technical Report

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.

Technical Review

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 Report

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.

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.
