Carbon capture and storage in Australia Carbon capture and storage in Australia Carbon capture and storage (CCS) is an approach to try to mitigate global warming by capturing carbon dioxide from large point sources such as fossil fuel power plants and storing it instead of releasing it into the atmosphere. Carbon capture and storage is also used to sequester filtered out of natural gas from certain from natural gas fields. While typically the has no value after being stored, Enhanced Oil Recovery uses to increase yield from declining oil fields. There are no currently-operating large-scale CCS projects in Australia, although the Gorgon gas project will qualify
Underground coal gasification Underground coal gasification Underground coal gasification (UCG) is an industrial process which converts coal into product gas. UCG is an "in-situ" gasification process carried out in non-mined coal seams using injection of oxidants, and bringing the product gas to surface through production wells drilled from the surface. The predominant product gases are methane, hydrogen, carbon monoxide and carbon dioxide. Ratios vary depending upon formation pressure, depth of coal and oxidant balance. Gas output may be combusted for electricity production. Alternatively gas can be used to produce synthetic natural gas or hydrogen and carbon monoxide can be used as a chemical
