TOKYO, Japan – INPEX, TotalEnergies and Woodside Energy have secured a greenhouse-gas storage assessment permit (G-7-AP) offshore northwest Australia, under their Bonaparte CCS Assessment joint venture.
The block, awarded under Australia’s 2021 Offshore Greenhouse Gas Storage Acreage Release, is in 30 m to 75 m of water in the Bonaparte Basin off the northwestern coast of the Northern Territory. According to INPEX, the area is thought to hold strong potential for subsurface storage of captured CO2.
INPEX will operate the block with a 53% interest, pursuing evaluation and appraisal work with its two partners from next year onward.
The company added that its Ichthys LNG development (in which TotalEnergies is also a partner) would be a natural user of this CCS solution, with an opportunity to prove up a large-scale carbon storage site for the Darwin-based, carbon capture, utilization and storage (CCUS) hub proposed by the Northern Territory Government.
Potentially this could become one of the world’s largest CCS projects, the company added.
