Study On Underground Coal Gasification Combined Cycle Coupled With On-Site Carbon Capture And Storage, Peng Pei
Theses and Dissertations
The North Dakota portion of the Williston basin holds huge, but economically unmineable lignite resources in the Fort Union formation. A technology coupling the underground coal gasification with carbon capture and storage (UCG-CCS) is proposed in this study to recover these lignite resources in North Dakota. The UCG-CCS system provides a cost-effective and environment-friendly approach to convert the lignite to electricity and beneficially utilize the by-product of CO2 at the same time. The target coal seam is the Harmon lignite in the Fort Union formation in western North Dakota. The main objectives of this study are to set up the …
