Summary
The projects have all proved successful under the most rigorous of environmental monitoring conditions. The tests and trials to date, along with the main conclusions from each one, are summarised in the table below. Finally, it should be noted that a number of trials have occurred in China, mainly using man-made underground galleries. A UCG research centre has also been created at the China University of Mining and Technology in Beijing.
