The Bonaparte carbon capture and storage (CCS) joint venture operated by Japan’s Inpex Browse E&P, TotalEnergies CCS Australia and Woodside Energy has started pre-front-end engineering design work.
The project is in the Bonaparte Basin, around 260km offshore Darwin in the Northern Territory of Australia. If all goes to plan, CO2 injections are slated to start around 2030.
Inpex believes it could become one of the largest CCS projects globally.

The joint venture aims to transport CO2 permanently offshore to the basin, which has potential storage capacity of more than 10 million tonnes per year. The vision behind the project is that it becomes an enabler for the development of a full CCS value chain, appealing to overseas industrial emitters as much as domestic ones.
It will now conduct detailed analysis of reservoir appraisal data to support ‘a declaration of identified GHG storage formation’.
The Ichthys LNG joint venture, involving Inpex, TotalEnergies and other Australian and Japanese partners, is expected to be the anchor customer of Bonaparte CCS. It has LNG production capacity of 9.3 mtpa.
