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.
Myth Busting – Misconceptions and Study Facts
CCS is not like LINC Energy i.e underground coal gasification (UCG)
CCS and Linc Energy’s underground coal gasification (UCG) project are two completely different activities. UCG technology essentially burns a coal seam underground while injecting oxygen or air to sustain combustion thus extracting energy and chemicals using a complex, high temperature underground procedure. CCS is the process of capturing carbon dioxide and injecting it into existing sandstone pore space deep underground for storage where it remains.
CTSCo is not a commercial enterprise to avoid any conflicts of commercial versus environmental interest. It is 100 percent grant funded and is obliged to report all its finding under Queensland’s Greenhouse Gas Storage Act 2009 to it grant funders: the Australian Government and ACALET (Australian Coal Association Low Emissions Technology)/COAL21 and to the Queensland Government. CTSCo operates on an ‘open book’/transparent basis with the relevant Queensland Government Departments.
CTSCo has implemented comprehensive baseline environmental monitoring to ensure that any potential effects of its pilot activities can be compared against the baseline. Should a permit be approved for the exploration stage storage testing activities, extensive monitoring and verification is to be undertaken with continuous reporting to Queensland Government Agencies.
Scientific studies associated with the CTSCo project are being undertaken by leading scientists, academics and researchers from universities and research institutions from across Australia and the world. These include CSIRO, University of Texas, University of Queensland, Australian National University, Curtin University and CO2CRC.
CCS is not like Coal Seam Gas (CSG)
Coal Seam Gas extraction involves drilling a coal seam between 200 and 800 metres deep, sometimes fracking (cracking open) the coal seams, with a mixture of water sand and chemicals to release the methane gas in the coal seams. Surplus water is treated through reverse osmosis and for pH adjustment and given to users OR reinjected into the same Precipice Sandstone being targeted for CCS.
Carbon Sequestration (or CCS) does not involve the addition of anything, other than CO2 captured from a power station (coal-based power generation at up to 90% capture in this case, but could be gas based power generation, steel manufacture or cement manufacture), injected to an aquifer at a depth of greater than 800 metres so that it stays liquid. Injected at 1200 metres or more and at the natural pressure down there of 1850 psi and natural temperature of 60 degrees Celsius, the CO2 has a density of greater than 1 so that it tends to sink when combined with water over a period of time.
CCS does not involve fracking. CO2 is a non-toxic substance that we breathe, drink, and essential to human life in a dilute form, and has industrial and surgical uses.
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.
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.
Previous term used
Rationale for change
It is understood that this study is not a commercial project and therefore there are no profits to be made. However using the term not-for-profit can be misleading as the study is not a charity which is often associated with not-for-profit. Therefore the community deemed the term non profit as more appropriate. However, wholly grant-funded is a more accurate description and is the term used by those involved in the study.
