Issue: Underground coal gasification (UCG) is a technology that has the potential to complement or even replace traditional methods of coal mining and surface gasification. New commercial UCG projects are being constructed in Australia, China, and India, and more projects are being considered. Appropriate site selection and application of the best UCG technology are complex processes, and a variety of technical and geological factors must be taken into consideration to evaluate each site being considered.
Objective: The main objective of the proposed project is to develop a generic underground coal gasification – carbon capture and storage (UCG-CCS) site characterization workflow which would address the dilemma faced by the proponents of reactor zone CO2 storage and offers technological solutions to source-sink mismatch issues that are likely to be faced in many coalfields.
Approach: This objective will be achieved through integrated research into the field-based technology knowledge gaps, such as cavity progression and geomechanics, potential groundwater contamination and subsidence impacts, together with research into process engineering solutions in order to assess the role/impact of site specific factors (coal type, depth/pressure, thickness, roof and floor rock strata, hydrology) and selected reagents on the operability of a given CO2 emission mitigation option in a coalfield.
Products: The project will produce a comprehensive report evaluating technology options for coupled underground coal gasification and CO2 capture and storage Durucan, S., Korre, A., Shi, J-Q, Idiens, M., Stanczyk, K., Kapusta, K., Rogut-Dabrowska, A., Kempka, T., Wolf K-H., Younger, P., Zavsek, S., Poulsen, N.E., Bojda, D., Franzsen, S., Muresan, M., Gao, J., Beath, A., Mastalerz, M., 2014.

Benefits: The intent of this evaluation is to provide better understanding of the UCG technology combined with CO2 Capture and Storage.
