Project description

The Australian Gas Infrastructure Group (AGIG) is evaluating the introduction of hydrogen into gas transmission and distribution networks and the renewable hydrogen supply chain

The Dampier-Bunbury Natural Gas Pipeline (DBNGP) is one of the largest capacity natural gas pipelines in Australia. It stretches approximately 1,600 kilometres and is the main transmission line supplying Perth and industry in Western Australia.

In 2021, AGIG completed a feasibility study supported by the Western Australian Government to determine if and how AGIG can introduce hydrogen into its DBNGP feedstock mix. The outcome of this study was a roadmap to introducing hydrogen into transmission pipelines.

The completed feasibility study identifies a clear pathway for declaring a pipeline section as suitable for use with hydrogen/natural gas blends. This pathway includes material testing, additional operational constraints and a realignment of regulatory and commercial frameworks.

AGIG plan to build on the feasibility study and partner with ATCO to develop the Clean Energy Innovation Park (CEIP) in Western Australia, delivering a commercial renewable hydrogen supply chain supported by AUD$28.7 million in funding from the Australian Renewable Energy Agency (ARENA).

Subject to achieving a Final Investment Decision, the CEIP is intended to establish a 10 megawatt (MW) electrolyser and plant capable of producing up to 4 tonnes of hydrogen per day, along with storage and delivery to the gas network injection points.


January 2020: The feasibility study for this project is one of seven feasibility studies to which funds were allocated by the Western Australian government under its Renewable Hydrogen Fund.

January 2022: The feasibility study for the project is completed and study published.
