Publication Overview

This analytical review was originally prepared as a discussion note for the executive committee of the IEA Greenhouse Gas R&D programme in response to concern resulting from publication in the USA of an academic paper claiming that methane emissions arising from the production of shale gas could be sufficient to make unconventional natural gas from that source more greenhouse intensive than coal. Such a claim runs counter to the conventional wisdom that converting an application from coal to natural gas invariably results in a reduction in the greenhouse gas (GHG) emission consequences of the application, particularly so for power generation

Publication Summary

The 1:2 GHG advantage of gas over coal for base load power generation is partly offset when precombustion GHG emissions are taken into account.  When the gas is sourced from shale with fracking, that GHG advantage of gas over coal would be reduced to 1:1.77.

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.

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.

Monitoring Network Meeting Report

  • 1 December 2023
  • Event Proceedings
  • Storage

The IEAGHG Monitoring Network aims to assess new technologies and techniques in the monitoring of CO₂ storage, determine the limitations, accuracy and applicability of monitoring techniques, disseminate information from research and pilot storage projects around the world, develop extensive monitoring guidelines for the different sub-categories of geological storage; oil and gas fields, unmineable coal seams, and saline aquifers covering the differing conditions and reservoir properties encountered globally as well as to engage with relevant regulatory bodies.

Components of CCS Infrastructure – Interim CO₂ Holding Options

  • 27 November 2023
  • Storage
  • Transport

This work, undertaken on behalf of IEAGHG by TNO and SINTEF, provides an overview of temporary / interim CO₂ storage, or ‘holding’, options (also called buffers) and investigates the role of buffer storage and its potential to create flexible and robust carbon capture and storage (CCS) chains. The report looks at current and emerging buffer technologies, conducts simulations to demonstrate the temporary storage required for given flow-rate scenarios and discusses the impact of buffer capacity on transport costs. In the report, the storage requested in the chain for normal operation is presented as " temporary storage" and storage to give buffer capacity is presented as " buffer storage". This report has focussed on buffering at the emitter site. The results of this study will benefit CO₂ storage site project developers, operators, financiers and regulators.
