Exhausted gas reservoirs could provide the solution to reducing global greenhouse gas emissions.
Researchers working on the CO2CRC Otway Project in Victoria have shown that depleted gas fields can be used to store significant amounts of our carbon dioxide emissions.
Since 2008, over 65,000 tonnes of CO2 rich gas has been injected, stored and monitored two kilometers underground in a depleted natural gas reservoir in the Otway Basin.
The project has demonstrated that the deep underground storage (‘geosequestration’ in technical terms) of CO2 is a technically and environmentally safe way to make deep cuts into Australia’s greenhouse gas emissions.
