PESA SA/NT November Luncheon

Moomba CCS – delivering a world leading CO₂ storage project

Anthony Western (Santos)

Abstract:

The Moomba Carbon Capture and Storage project is a large-scale CCS project at the Moomba Gas Plant in the Cooper Basin, South Australia. New facilities were constructed to capture, dehydrate, transport and permanently store CO2 emissions that were previously vented to atmosphere and depleted gas fields were selected as the initial storage reservoirs. Five new injection wells were drilled, and existing wells were re-purposed as monitoring wells to enable the Monitoring and Verification (M&V) plan including environmental assurance monitoring.

The Moomba CCS project commenced operations in September 2024 and by June 2025 had safely captured and permanently stored more than 1.0 million tonnes of CO2 emissions. The wells and storage reservoir are performing as expected and monitoring wells are seeing signs of CO2 injection in line with reservoir model predictions. At 1.7 Mtpa CO2e, it is one of the largest CCS projects in the world and its successful startup and early performance has enabled future CCS growth in the Cooper Basin.

This presentation will give an overview of the Moomba CCS project and share some of the results to date, with a focus on subsurface scope.
