A three way partnership operated by Chevron Corp. has obtained a greenhouse fuel evaluation allow to evaluate the potential for carbon dioxide (CO2) seize and storage (CCS) within the Northern Carnarvon Basin offshore Western Australia.
The G-20-AP allow covers an space of two,222 sq. kilometers (857.92 miles) adjoining to Barrow Island, Chevron Australia Pty. Ltd. mentioned in a press release.
“Carbon seize and storage is a vital software and this allow award demonstrates the potential to decrease the carbon depth of our operations in addition to doubtlessly third-party emissions”, Chevron Australia vitality transition normal supervisor David Fallon mentioned.

Chevron Australia’s companions are Mobil Australia Sources Co. Pty. Ltd. and Shell Australia Pty. Ltd.
“Chevron and the Joint Enterprise will now begin to assess the technical and business feasibility of the geological storage of carbon dioxide within the allow space”, mentioned the assertion on Chevron Australia’s web site.
Final August Chevron Australia introduced an identical allow for an space spanning about 8,467 sq. kilometers (3,269.1 miles) offshore Onslow, Western Australia, in the identical basin.
The G-18-AP allow went to a separate three way partnership additionally operated by United States oil large Chevron. The co-venturer is Australia’s Woodside Vitality Group Ltd.
Chevron Australia additionally holds non-operating stakes in CCS evaluation permits G-9-AP, G-10-AP and G-11-AP.
Chevron Australia already has an working CCS injection system. On August 8, 2019, Chevron Australia introduced the beginning of operation of the venture at its Gorgon fuel facility on Barrow Island.
Nevertheless, Gorgon CCS captured within the final fiscal yr (FY) simply 30 % of the carbon dioxide (CO2) emitted from pure fuel extraction by the Gorgon LNG and home fuel venture, in response to the Institute for Vitality Economics and Monetary Evaluation (IEEFA).
The underperformance displays a pattern amongst CCS initiatives throughout the globe and casts doubt “on the monetary viability of bold CCS plans by Australian governments and corporations”, IEEFA reported November 28.
FY2023–24 marks the carbon seize and storage (CCS) venture’s lowest efficiency because it began working August 2019, IEEFA mentioned November 28, 2024. Gorgon CCS had a seize fee of 34 % in FY2022–23 and 33 % in FY2021–22, in response to calculations by the Cleveland, Ohio-based assume tank. Chevron Australia’s monetary yr begins July and ends the next June.
The CCS venture had been authorized on the situation it captures, on a five-year rolling common from 2016, no less than 80 % of CO2 emissions from wells drilled for the fuel facility, in response to data printed on-line by Chevron Australia. The fuel facility, which has a liquefied pure fuel (LNG) capability of 15.6 million tons every year and a home fuel provide capability of 300 terajoules a day, sources feed from the Gorgon and Jansz-Io fuel fields.
Chevron Australia says in a web based truth sheet it’s “dedicated to growing carbon dioxide injection charges at Gorgon CCS in accordance with its environmental approvals”.
“A venture has commenced that goals to broaden the system’s capability to handle water discovered inside the reservoir the place carbon dioxide is saved, thereby decreasing reservoir stress and enabling elevated carbon dioxide injection charges”, the actual fact sheet states.
“Along with this venture, Chevron Australia continues to discover choices to additional improve carbon dioxide injection charges inside the system”, it provides.
Chevron says it’s creating CCS initiatives as each a enterprise alternative and a method of reaching its aim of internet zero upstream emissions by 2050.
