Publication Overview

IEA GHG has produced a revised set of criteria for assessment of plants, particularly power plants with CO₂ capture, making use of information from EPRI and others. The revised criteria should be used by IEA GHG for its future studies. Other organisations are encouraged to use the criteria to provide consistency of results. Preliminary criteria have been specified for alternative locations and these should be finalised with local organisations at the time when IEA GHG undertakes its first study for each alternative location. Other alternative locations could be considered in future, at the request of IEA GHG’s members. As a follow on to this report IEA GHG will assess the feasibility of providing standard assessment criteria for CO₂ transport and storage and it will develop methodologies for comparing the relative merits of CCS and alternative low-CO₂ technologies.

Publication Summary

With respect to the Otway Project monitoring program, the expert review team considered that:

  1. In general the capacity, reliability, accuracy of many elements of the monitoring processes, are being demonstrated in the year since injection commenced, although as might be expected for a pilot test some techniques suffered from equipment reliability issues.
  2. Findings to date are consistent with model predictions about the injection stream (principally the CO2 plume).
  3. Although some techniques demonstrated understanding and appropriate handling of the uncertainties in the monitoring and verification (M&V), in general there was insufficient reporting of these.
  4. The monitoring programme was technically sound. Some assurance techniques would benefit from more consideration on expected responses for potential leakage scenarios.
  5. The overall Monitoring and Verification approach is comprehensive, fulfils the requirements and is achievable within the programme schedule.

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.

  • 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.

  • 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.
