The Blue Energy Bowen Gas Pipeline is a proposed natural gas pipeline.[1]

Location

The pipeline would run from the proposed Bowen Gas Project in the Bowen Basin, Queensland to Gladstone, Queensland.

Project Details

  • Operator: Blue Energy
  • Parent Company: Blue Energy
  • Proposed Capacity: 300 terajoules per day (284.35 million cubic feet per day)
  • Length: 311 Miles / 500 kilometers
  • Status: Proposed
  • Start Year: 2023

Background

In June 2017 a memorandum of understanding (MOU) to build the pipeline was signed by Blue Energy and the APA Group.[2] In April 2020 Blue Energy announced that it had begun a pre-feasibility study for the project and was discussing it with the Federal and Queensland governments.[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.
