The Anglo-Mitsui Gas Pipeline is an operating natural gas pipeline.[1]


The pipeline runs from the Dawson coal mine in Kianga, Queensland to the Queensland Gas Pipeline and the Queensland Nitrates plant near the town of Moura in central Queensland. The pipeline's exact route appears on p.36 of its August 2007 letter of approval from the Australian Energy Regulator.[2]

The Anglo-Mitsui Gas Pipeline, formerly known as the Peabody Mitsui Gas Pipeline, was commissioned in 1996.[2] Gas is supplied from coal seam drainage operations at the Dawson Mine.[1]

Coal seam gas

Coal seam gas is found in coal seams, where underground water pressure keeps it contained. Pumping water out of the coal seam releases this pressure and allows gas to escape from the coal into a well.[3] Coal seam gas wells produce large volumes of water (averaging 10,000 litres of water per day per well in Queensland). This water can contain salt and other contaminants that exist normally in coal seams in varying concentrations.[3]

According to the environmental group Lock The Gate Alliance, the impacts of coal seam gas mining include "encroachment on good farming land, disruption of other land uses and industries, clearing of bushland, air pollution, contamination or depletion of ground or surface water, pollution of waterways, health impacts on workers and nearby residents, and damage to biodiversity."[4]

The practice also raises concerns about global warming because methane is a relatively potent greenhouse gas with a high global warming potential 72 times that of carbon dioxide (averaged over 20 years) or 25 times that of carbon dioxide (averaged over 100 years), according to the IPCC's Third Assessment Report.[5] (Note that the global warming potential of methane was estimated at 21 times that of carbon dioxide, averaged over 100 years, in the IPCC Second Assessment Report, and the 21 figure is currently used for regulatory purposes in the United States.[6]) Methane in the atmosphere is eventually oxidized, producing carbon dioxide and water. This breakdown accounts for the decline in the global warming potential of methane over longer periods of time.
