An Overview of the Chinese UCG Program
Data Science Journal, 2007 Coal is the dominant source of energy in China, but about 50% of the coal resource is left underground unmined. Because of this, the "long-tunnel, large section, two-stage" Underground Coal Gasification (UCG) technology has been put forward, and the UCG ...

Mobilizing mine lands for biobased decarbonization strategies
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Over 163 000 ha of mine lands in Pennsylvania (PA) have the potential to produce willow as a feedstock for renewable energy generation. Each year these lands could produce between 454 000 and 907 000 dry Mg of willow, which can be a feedstock for bioenergy (i.e., biopower) with carbon capture and sequestration (BECCS) or sustainable aviation ...

Effect of Injection Flow Rate on Product Gas Quality in Underground Coal Gasification (UCG) Based on Laboratory Scale Experiment: Development of Co-Axial UCG System [PDF]
, 2017 Underground coal gasification (UCG) is a technique to recover coal energy without mining by converting coal into a valuable gas. Model UCG experiments on a laboratory scale were carried out under a low flow rate (6~12 L/min) and a high flow rate (15~30 L/
