Collie South West CO2 Hub
To develop multi-user infrastructure for CO2 capture and storage
Southern Perth Basin
The Collie-South West CO2 Geosequestration Hub is a proposal by the Western Australian Department of Mines and Petroleum and a consortium of major industrial emitters in the south west area of Western Australia, at Collie and Kwinana. Participants include two coal mines, two alumina refineries, two power generators and a coal-to-urea project at Collie. The hub has been selected for funding under the Australian government's AU$2 billion CCS Flagships Program.
The project aims to use pre and post-combustion technologies to capture around 2.5 million tonnes of CO2 per annum, which would be stored in geological formations in the Southern Perth Basin - partners are currently working on a four-year research project to determine the long-term storage potential of the Lesueur Sandstone Formation there. The proposed Collie-Harvey CO2 transport pipeline is about 80km long and the Kwinana-Harvey pipeline 100km long.
The plans have already received state and industry funding. In June 2009, funding for a geosequestration study by Schlumberger was agreed in a Memorandum of Understanding between Western Australia’s Department of Mines & Petroleum and five companies – Verve Energy, BHP Billiton, Griffin Energy, Wesfarmers Premier Coal and Perdaman Chemicals & Fertilisers. Alcoa Australia has since joined the project.
The CCS Flagships Program – part of the $5.1 billion Clean Energy Initiative – chose the Collie hub proposal because of its proximity both to large-scale industrial emitters of CO2 and potentially suitable storage sites. Initial studies identified the Lesueur formation in the Southern Perth Basin as a potential storage site. In March 2012, the Department of Mines and Petroleum completed a drilling programme in Harvey, which retrieved data from up to three kilometres underground.
In November 2011, Australia's national science agency CSIRO published a literature review as part of the management of basin resources, and of direct relevance to the Collie Hub, CarbonNet and Wandoan CCS projects. This review contains information on identified resources, geological assessments and an analysis of data still required by the three key projects.
National Geosequestration Laboratory
This national research facility opened in September 2012 to develop technologies to reduce risk and uncertainty around long-term underground CO2 storage. Based at the Australian Resources Research Centre in Perth, it is a collaboration of research agency CSIRO and the universities of Western Australia and Curtin. The NGL and its satellite research facilities was set up to support CCS Flagships Program projects, including Collie. The federal government provided funding of $48.4 million. Find out more about NGL here.
Federal and State governments have committed $350 million of funding, with the bulk of this funding coming from the Australian Government through the CCS Flagships Program. The Department of Mines and Petroleum is playing a significant facilitating role for the early part of the project.
An unincorporated joint venture agreement between the partners will guide the commercial project that leads to CO2 transport and trial injection. The project has completed a 2D acqusition survey. The initial drilling programme confirmed in October 2012 the existence of the Lesueur reservoir 2.5 kilometres underground. The project team is now planning for the second drilling programme and 3D seismic mapping to be carried out in 2013. The project is provisionally scheduled to go online in 2015.

Collie has the potential to capture and store up to 6.5 million tonnes of CO2 a year for 40 years from industrial sources. The Lesueur project will be the first project operating under Western Australia’s new Green House Gas legislation, amendments to the Petroleum and Geothermal Energy Resources Act 1967 and the Petroleum Pipelines Act 1969.
When completed, the Gorgon and Collie South West Hub projects will have a combined potential to store more than eight million tonnes of CO2 per annum, or around 11% of Western Australia's annual current emissions.
