The CO2CRC study has found the Perth Basin, particularly the Gage Sandstone reservoir in the Vlaming Sub-basin, has good potential for CO2 geosequestration.
Plans have just been announced to build Australia’s first hydrogen production plant in the Kwinana industrial region, south of Perth.
The plant would use fossil fuel to produce the hydrogen, which would then be used to generate clean electricity.
Carbon dioxide is a by-product of the process but the work of CO2CRC indicates that there is scope to use the nearby geological storage site, which would prevent the CO2 from entering the atmosphere.
CO2CRC scientists developed a range of scenarios from hydrodynamic (movement of water in the sandstone) to economic models and assessed risks including leakage and came to the conclusion that the offshore Perth Basin was potentially suitable for storage of CO2 emissions.
CO2CRC chief executive Dr Peter Cook said the Perth Basin and other offshore areas could be very important to Australia as it develops options for making deep cuts in its greenhouse gas emissions.
