Norwegian firm to assess carbon storage potential in Australia’s offshore basin

February 13, 2025, by Nadja Skopljak

Norway-based energy data and intelligence company TGS and Australian commercial-scale carbon capture and storage (CCS) project developer and operator deepC Store have joined forces on carbon storage assessment in the Browse Basin offshore Australia.

The partners entered into an agreement to carry out subsurface well location planning, storage resource verification and evaluation for carbon storage in the G-14-AP permit area in the Browse Basin.

The permit is one of two offshore CO2 storage acreages awarded to deepC Store and Azuli by the Australian Commonwealth Government in August 2024, alongside the G13-AP permit.

DeepC Store is the designated operator of the G-14-AP permit and the associated CStore1 project, with an estimated CO2 storage potential of approximately 1 gigatonne (1 billion tonnes) in the permit area.

“We are very pleased to work with TGS for progressing one of its key technical activities for G-14-AP. This relationship is an essential component of our world class CO2 storage development. This work demonstrates our ongoing commitment to establish CStore1 as the first offshore floating CCS hub project in the Asia Pacific region, and to advance Australia’s strategic position in the CCS business,” said deepC Store’s Managing Director Daein Cha.

The assessment will take place throughout 2025 on the permit.

TGS noted that the integration of its advanced subsurface data and deepC Store’s expertise in CCS project development will be essential in assessing the feasibility and long-term security of carbon storage in the Browse Basin.

“We are delighted to see our collaboration with deepC Store evolve into actionable projects and services, following the recent award of Carbon Storage acreage in Australia,” said TGS EVP New Energy Solutions, Will Ashby. “This project underscores Australia’s vast potential while reaffirming TGS’ commitment to supporting global climate goals and enabling CCS developers to make tangible progress.”
