DOIIS announces carbon capture and storage funding in Surat Basin
On the 12 August 2016, the Department of Industry, Innovation and Science (DOIIS) announced $8.775 million of Federal Government funding to CTSCo for its carbon capture and storage project in Queensland’s Surat Basin.
Local community input
Recent feedback from the local community has helped us refine how we talk about our study. This community insight has been very important in helping us better explain what we are doing and how we are doing it.

Myth Busting – Misconceptions and Study Facts
What is carbon dioxide (CO2)?
Carbon dioxide (chemical formula CO2) is a colourless and odourless gas vital to life on Earth. This naturally occurring chemical compound is made up of a carbon atom covalently double bonded to two oxygen atoms. Carbon dioxide exists in Earth's atmosphere as a trace gas at a concentration of about 0.04 percent (400 ppm) by volume. Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, in ice caps and glaciers and also in seawater. It is present in deposits of petroleum and natural gas.
What is a supercritical liquid (CO2)?
Supercritical carbon dioxide (sCO2) is a fluid state of carbon dioxide where it is held at or above its critical temperature and critical pressure. Carbon dioxide usually behaves as a gas in air at standard temperature and pressure (STP), or as a solid called dry ice when frozen. If the temperature and pressure are both increased from STP to be at or above the critical point for carbon dioxide, it will have the properties midway between a gas and a liquid. More specifically, it behaves as a supercritical fluid above its critical temperature (304.25 K, 31.10 °C, 87.98 °F) and critical pressure (72.9 atm, 7.39 MPa, 1,071 psi), expanding to fill its container like a gas but with a density like that of a liquid.
What is the Precipice Sandstone?
The Jurassic age Precipice Sandstone is the basal formation in the Surat Basin and forms part of an extensive fluviatile sedimentary unit which extends from the coastal regions of south-eastern Queensland and northeastern New South Wales westward to the vicinity of Charleville in southern Queensland.
The formation crops out along the present northern margin of the Surat Basin, approximately 150 km to the north and northwest of the Glenhaven area, where it forms distinctive steep bluffs. Its eastern and western extent is controlled by non deposition and/or erosion.
