Introduction

The IEA Greenhouse Gas R&D Programme (IEA GHG) commissioned Imperial College London, to undertake a review of the international state of the art in risk assessment guidelines and proposed terminology for use in CO2 geological storage.

The need for this study was identified during the 3rd meeting of the IEA GHG international storage research network on risk assessment, held at Imperial College.

Conclusions and Recommendations

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).
