Catalyst: Coal seam gas production

The latest coal rush is sweeping across Queensland, but this time without having to dig the coal up. Animations show the processes used to extract coal seam gas (CSG) out of the ground, which can then fuel gas turbines in power stations. Discover how CSG avoids some of the environmental effects of traditional coal mining, ...
