Preface Queensland is a major producer of electricity, derived overwhelmingly from coal but with coal seam methane an increasingly important energy source. As a result of this high level of dependency on fossil fuels, Queensland is also a large scale emitter of carbon dioxide. The State has no wish to limit its access to cost effective energy but at the same time seeks to contribute to the overall objective of decreasing Australia’s greenhouse gas signature. One of the options for doing this lies with the application of carbon dioxide capture and storage (CCS) or geosequestration to major stationary emissions. This report outlines a study of a part of Queensland’s Bowen Basin, where a detailed study of CO 2 storage capacity has been undertaken by a large number of CO2CRC researchers from a range of institutions. The study provides an excellent example of the type of work that must be undertaken if we are to effectively characterize a geological storage site and demonstrate that it will meet the requirements of storage security and capacity. The study convincingly demonstrates that the Wunger Ridge is likely to be technically suitable as a CO 2 storage site. Obviously more work is necessary to turn that potential into a technical and economic reality but this Report represents a very important first step. I thank all the researchers for their work and also the peer reviewers for their contribution. Peter J.
