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 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 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.

Power CCS: Potential for cost reductions and improvements

  • 5 August 2024
  • Capture
  • Costs of CCUS

CCS, in the context of power CCS technologies, will be an essential component of the portfolio of technologies required to reach net-zero emissions in the power sector. This study explores the potential to reduce the cost and accelerate the uptake of power CCS technologies.

Techno-Economic Assessment of Small-Scale Carbon Capture for Industrial and Power Systems

  • 1 March 2024
  • Capture
  • Costs of CCUS

This study, undertaken on behalf of IEAGHG by Element Energy (now a part of ERM), explores the role of CCS in decarbonising small-scale industry and power generation applications. While relatively under investigated compared to their larger scale counterparts, reaching net zero will be dependent on successfully addressing the emissions from small-scale facilities. The findings from the study will be of interest to the broader energy community but, in particular, should benefit project developers, the finance community and policymakers.

Technical Report

Clean steel an environmental and technoeconomic outlook of a disruptive technology

  • 1 March 2024
  • Capture
  • Costs of CCUS

This study primarily presents a comparative analysis of steelmaking pathways to cost-effectively decarbonise a steel mill, taking a life-cycle perspective on associated environmental impacts. The roll-out of clean steel technologies is envisioned to have a significant implication for support infrastructure. Therefore, a secondary objective of the study is to gain insights into the primary energy and infrastructure implications associated with large-scale deployment of different steel decarbonisation pathways. Clean steel production will likely be more expensive than steel produced today; this poses additional economic strains on steel producers and consumers. Consequently, a third objective is to estimate the price premium that clean steel could command in existing and future markets. Further, this study formulates recommendations for key stakeholders to support the sector and outlines recommendations for further work.

The Role of Indices in Assessing the Maturity of CCUS Technologies and their Readiness for Deployment

  • 1 February 2024
  • Industry Insights

This study was undertaken on behalf of IEAGHG by Foresight Transitions Ltd. While a technology may be technically mature, it has become increasingly clear that the technology may not necessarily be considered commercially ‘bankable’ by investors. In this study, the potential for an index or indices to provide that confidence was explored. The findings from the study will be of interest to the broader energy community but, in particular, should benefit technology developers, CCUS end users, investors and policymakers.

Methologies and Technologies for Mitigation

  • 1 December 2023
  • Industry Insights

The driver behind this study is to develop a report built on the on the previous IEAGHG report on methods of leakage mitigation (2007/11). The proposed study should focus on current mitigation and remediation methods that may be applied or considered in site specific conditions in the event of unpredicted CO2 migration. Each geological storage site will have an adaptive site specific monitoring plan, based on a risk assessment. Detection of a significant irregularity may involve supplementing the monitoring program, in order to detect a possible leak and if necessary engaging mitigation measures.
