A Review of the In’tl State of the Art in Risk Assessment Guidelines and Proposed Termimology for Use in CO₂ Geological Storage

Publication Overview

The work carried out included the following key elements:

• Review of the international terminology and regulations with a focus on public health and engineering systems risk assessment and management;
• Compilation of generic and specific terminology for risk assessment and management relevant for CO₂ geological storage;
• A formal report of the methods used, results and conclusions.

The report includes an updated version of the risk management framework that incorporates the Framework for Risk Assessment and Management of Storage of CO₂ Streams in Geological Formations (FRAM) and the European Union CO₂ Capture and Storage (EU CCS) directive steps, which is also consistent with the human health and ecological risk assessment workflows, as well as the Standards Australian/ Standards New Zealand (AS/NZS) for environmental risk management and security risk management. The report also includes a comprehensive list of terms used in various risk publications and extensive reference list.

Publication Summary

The study report provides an important reference document on risk management frameworks and risk terminology in the context of CO₂ geological storage.

The report should be made widely available to practitioners in geological storage through future meetings of the IEA GHG risk assessment network and the International Performance Assessment Centre (IPAC).
