Since starting its greenhouse gas (GHG) injection project at its Gorgon LNG facility, Chevron Australia will soon reach five million tonnes of GHG safety stored at the facility.

Equivalent to taking more than 1.6 million passenger vehicles off Australia’s roads for a year, the injection of five million tonnes of carbon dioxide equivalent (Co2e) represents the largest volume of injection by any comparable carbon capture and storage (CCS) system within the same time frame.

Commenting on the milestone, Mark Hatfield, Managing Director, Chevron Australia, said, “This significant milestone shows how we’re deploying technology, innovation and skills to deliver cleaner energy and reduce our carbon footprint.”

“The Gorgon carbon capture and storage system is the biggest CCS system designed to capture carbon emissions and is demonstrating Australia’s world-leading capability in the area.”

Chevron applies this CCS system by taking CO2 from offshore gas reservoirs and injecting it into a giant sandstone formation two kilometres under Barrow Island, where it’s trapped. This system will reduce GHG emissions by over 100 million tonnes over the life of the injection project.

Despite the significant reductions Gorgon’s emissions, Hatfield said that the time taken to safely start the system meant Chevron had not met injection requirements.

He went on to say, “Chevron is working with the WA regulator on making up the shortfall and will report publicly on that later in the year.”

“Like any pioneering endeavour, it takes time to optimise a new system to ensure it performs reliably over 40-plus years of operation.”

“The road hasn’t always been smooth, but the challenges we’ve faced – and overcome – make it easier for those who aspire to reduce their emissions through CCS.”

Hatfield also added that Chevron are committed to sharing the lessons they’ve learned with state and federal governments, research institutes and other energy producers to assist the deployment of CCS in Australia.
