Designing of Underground Coal Gasification Unit

Journal of Advanced Research in Fluid Mechanics and Thermal Sciences, 2020
Pakistan is one of the biggest country for coal reserves in the world. Those coal reserves if exploited, will help in fulfilling the growing need of Pakistan’s energy sector. The ultimate goal for “Underground Coal Gasification” is to design a new system that can produce sufficient electricity and is relatively cleaner and environment-friendly.

Thermo‐Mechanical Analysis of Crack Propagation Process in Heterogeneous Brittle Coal and Its Effects on the UCG Cavity Growth Rate

Energy Science &Engineering, Volume 13, Issue 3, Page 1062-1078, March 2025.
Increasing cavity temperature causes an exponential increase in thermal stress and the number of created cracks. Therefore, UCG cavity growth escalates with an increasing cavity temperature ABSTRACT The mechanism of cavity growth in a UCG process is mainly dependent on the presence of fractures and microcracks in the coal seam.

Recent Material Advances in Carbon Dioxide (CO2) Capture From Power Plant Flue Gases: Toward Achieving Net Zero Emissions

Energy Science &Engineering, Volume 13, Issue 3, Page 980-994, March 2025.
ABSTRACT Climate change is caused by an increase in global temperatures, known as global warming. This is largely attributed to the rising levels of greenhouse gases in the atmosphere, with carbon dioxide emissions from fossil fuel power plants being the major culprit. Implementing carbon capture, utilization, and storage (CCUS) strategies is essential

Coal Seam Roof and Floor Lithology Prediction for Underground Coal Gasification Based on Deep Residual Shrinkage Network

Energy Science &Engineering, Volume 13, Issue 3, Page 1361-1374, March 2025.
This study proposes the deep residual shrinkage network (DRSN), a model combining advanced strategies for rapid and accurate lithology prediction. It enables efficient lithology evaluation in early underground coal gasification. ABSTRACT Lithology identification is a crucial task in coal underground gasification projects, serving as a prerequisite for ...

Potential U.S. Production of Liquid Hydrocarbons From Biomass With Addition of Massive External Heat and Hydrogen Inputs

GCB Bioenergy, Volume 17, Issue 2, February 2025.
This study examines the future potential of the U.S. to convert biomass into liquid hydrocarbons, leveraging external low‐carbon heat and hydrogen to prioritise biomass foremost as a carbon feedstock. Using three market scenarios from the 2023 Billion‐Ton Report and two augmented cases, we estimate a mature‐market production potential ranging from 4791
