Bonaparte CCS

Inpex Browse E&P, together with TotalEnergies CCS Australia and Woodside Energy, is developing the Bonaparte Carbon Capture and Storage (CCS) Project in Block G-7-AP located about 260 km offshore from Darwin in the Petrel Sub-basin (Bonaparte Basin). The initiative, initiated in 2022, is conducting appraisal work—including 3D seismic surveys and drilling of two wells—which has confirmed a high-quality saline aquifer with thick caprock formations suitable for safe, long-term CO₂ storage, with capacity estimated at over 10 million tonnes annually. The project commenced its pre-Front-End Engineering Design (pre-FEED) phase in April 2025 and has received Major Project Status from the Australian government—the first offshore CCS initiative in the country to be granted this recognition. Preparations are underway toward a Declaration of Identified GHG Storage Formation and securing a GHG injection license, with CO₂ injection planned to begin around 2030. The Bonaparte CCS is poised to become one of the world’s largest commercial CCS facilities, supporting decarbonization of industrial emitters in northern Australia and the broader Asia-Pacific region.
