Simulation and Modeling of Underground Coal Gasification Using Porous Medium Approach
… declining fossil fuel resources continue to make coal deposits a primary source of energy. However, the process of converting coal into valuable syngas through surface gasification requires conventional mining, extraction, transportation, storage, surface processing, ash and environmental …

Site Characterization, Sustainability Evaluation and Life Cycle Emissions Assessment of Underground Coal Gasification
Underground Coal Gasification (UCG), although not a new concept, is now attracting considerable global attention as a viable process to provide a "clean" and economic fuel from coal. Climate change legislation and the declining position of coal reserves (i.e., deeper and thinner seams) in many …

Study on underground coal gasification combined cycle coupled with on-site carbon capture and storage
… 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 …

Numerical analysis of thermal, hydraulic and mechanical processes in the near- and far-field of underground coal gasification reactors
Die Untertagevergasung von Kohle (UTV) ermöglicht die Erschließung konventionell nicht förderbarer Kohleressourcen und bietet dadurch Potenzial zur Erhöhung der weltweiten Kohlereserven. Bei der in-situ Kohleumwandlung entsteht ein hochkalorisches Synthesegas, das elektrifiziert oder zur Gewinnung …

Design and evaluation of integrated waste to energy multigenerational systems
… energy. Finally, the third system is an underground coal gasification system in which low-grade lignite is considered waste and used as fuel. Hydrogen, ethanol, electricity, heating, cooling, and sulfuric acid are produced for the communities in Konya in Turkey, Tuscany in Italy, and …
