CSG is natural gas, trapped in underground coal seams by water and ground pressure. Its single largest component is methane.

Natural gas, including CSG, is used for home cooking and heating, to generate electricity and also for industry to make a vast range of products.

CSG accounts for about 90 per cent of Queensland's natural gas supply and fuels about 17 per cent of the state's electricity generation.

Arrow has supplied CSG commercially to the Queensland domestic market since 2004 and today supplies nearly 20 per cent of Queensland's gas, most of which is used for power generation.

What is liquefied natural gas (LNG)?

LNG is natural gas that has been cooled and converted to liquid. At -161 degrees, it has about 1/600th the volume of room temperature natural gas, making it easier to store and transport. 

LNG is odourless, colourless, non-toxic and non-corrosive.
