Abstract: An assessment of the carbon dioxide (CO2) storage options in currently unmineable coal seams of the Waikato and King Country regions and preliminary estimates of storage capacity are herein reviewed. The results of laboratory testing to help understand the CO2 adsorption characteristics of Waikato coals are also presented. Following an introduction outlining the concept of greenhouse gas reduction using carbon capture and storage (CCS), the findings are presented in four parts comprising: 1. An overview of the Waikato coal resource and potential storage options; 2. Investigations into the properties of Waikato coals relevant to CO2 storage potential; 3. Carbon dioxide storage capacity estimates for areas of potentially unmineable Waikato coal; 4. A preliminary assessment of the potential for CO2 storage in King Country coalfields (sometimes referred to as Taranaki coalfields) and estimates of theoretical storage capacity. (auth)
