Publication Overview

The study aimed to review current laws and emerging CCS specific regulations, in different regions of the world and under different legal frameworks, concentrating on long-term liability aspects. The primary work of the study was to investigate and assess the various potential financial mechanisms for supporting CO₂ liability, including an assessment of their applicability and practicality to all parties concerned, and provide recommendations based on the findings. As well as discussion on important issues such as when and how transfer of liability to the government should occur, and what these liabilities could be, the study focuses primarily on how this liability can be supported.

Publication Summary

Government financial requirements primarily protect the government/taxpayer from the risk of the operator’s failing to fulfil its obligations, although some acceptable financial mechanisms also may serve as a funding source for the operator.  On the other hand, for the benefit of shareholders/owners, an operator may propose a variety of positions regarding its exposure to long-term CCS liabilities, ranging from use of a financial mechanism to self-insurance without a financial mechanism (subject to agreement by the relevant authorities).

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.

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.

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.

6th International Workshop on Offshore Geologic CO₂ Storage

  • 1 December 2023
  • Event Proceedings
  • Storage

The 6th International Workshop on Offshore Geologic CO₂ Storage was held in Aberdeen on 13-14 September. Organised with the University of Texas and hosted by the University of Aberdeen. The loca on was very appropriate as we were co-hosted and sponsored by Storegga who leads the Acorn project nearby in Scotland. This project had been recently announced by the UK government as a Track 2 Cluster project. This 6th workshop had 190 delegates (60 in-person and 130 virtual) from 35 countries, with a good mix of industry, researchers and regulators.
