Surat Basin Carbon Capture and Storage Project

Project overview

Current stage


  • The proposed trial project aims to demonstrate the effective permanent storage of captured carbon dioxide (CO2).
  • Transportation of a greenhouse gas (GHG) stream by truck from the Millmerran Power Station for 260 kilometres (km) to the test injection site located on EPQ10, near Moonie.
  • Construction of a transport facility to transfer the GHG stream (predominantly CO2) from trucks to holding tanks.
  • Conversion of the GHG stream from a cryogenic liquid to a supercritical fluid using a water bath heater and pump.
  • Construction of a nine-kilometre flowline to carry the GHG stream from the transport facility to the injection well.
  • Test injection of up to 110,000 tonnes per year for three years of the GHG stream via the injection well into the Precipice sandstone aquifer, between 2,250 metres (m) to 2,350m below the surface.
  • Monitoring to occur prior to and during the injection period, and for two years after injection has ceased, for a period of at least five years.


  • Carbon Transport and Storage Corporation (CTSCo) Pty Limited.


  • Within the tenement EPQ10, approximately 44km southwest of Moonie in southern Queensland.

Local government

  • Western Downs Regional Council.


  • Approximately 7 years.


  • Up to 32 (all program phases).
  • Approximately 5 (operational).

Commonwealth approval not needed

  • Not a controlled action under the Commonwealth Environmental Protection and Biodiversity Conservation Act 1999; EPBC (2021/9122).
