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.

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.

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.

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.

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.

7th International Workshop on Offshore Geologic CO2 Storage

• 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.

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.

Measurement, reporting and verification and accounting for carbon dioxide removal in the context of both project-based approaches and national greenhouse gas inventories

• 15 October 2024
• Industry Insights
• Policy & Regulation

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.

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.

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.

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.
