Solid Energy has successfully commissioned its $22 million underground coal gasification pilot plant near Huntly in the Waikato region, New Zealand, and the plant is now producing synthetic gas from coal.
Solid Energy said that it believes it is the first in the world to access energy from a single coal field using four different technologies: underground mining, open-cast mining, CSG, and underground coal gasification (UCG).
The company said that UCG can access energy from deep coal seams that are uneconomic using conventional mining technology and, compared to conventional mining, has significantly reduced environmental impacts and safety risks.
