New partnership to transform Moomba CCS into an international decarbonisation hub

Santos and APA Group have signed a Memorandum of Understanding (MOU) to assess decarbonisation opportunities by linking heavy CO2 emitters and import locations to Santos’ Moomba CCS facility.

The collaboration will include the evaluation of CCS pipeline transport routes from crucial emission sources in Gladstone, Port Bonython, and Greater Sydney to the Moomba CCS facility in the Cooper Basin, pending internal and external approvals and a finalised project agreement.

Santos’ Moomba CCS project is the most advanced of three planned CCS hubs in Australia, with Phase 1 able to store up to 1.7 million tonnes of CO2 annually. This equates to more than a quarter of the emissions reductions achieved in Australia’s electricity industry in the fiscal year ending March 2023.

Actual volumes stored at Moomba CCS will be determined by the amount of gas produced in the Cooper Basin, which will dictate the amount of CO2 available for storage. The first injection is scheduled to begin in 2024.


Santos Energy Solutions Executive Vice President Alan Stuart-Grant stated that working with APA will expedite the delivery of large-scale, low-cost CCS services to domestic and international emitters.

“I am very excited about the growth potential for carbon storage services at Moomba. Santos has already booked 100 million tonnes of carbon storage resource in the Cooper Basin in South Australia. The Cooper and Eromanga Basins have enormous carbon storage capacity, with the potential to store up to 20 million tonnes of CO2 per year for up to 50 years,” Stuart-Grant said.

According to him, Santos possesses the expertise and infrastructure to deliver low-cost, large-scale CCS and decarbonisation technologies crucial for achieving net zero by 2050.

“Santos is seeing surging international and domestic demand for our CCS capabilities in the Cooper Basin and this new partnership will put us in a leading position in what is essentially a new industry which will help drive the decarbonisation of our region. Importantly, it is an industry that can utilise the skills of our existing workforce and secure their jobs for decades to come,” he added.

“Beyond the near-term carbon abatement opportunity, this MOU also paves the way for Moomba to become a low carbon fuels hub as technology is unlocked and market demand continues to increase through the energy transition. We are determined to deliver reliable, affordable, lower-carbon energy to our customers,” he continued.

The International Energy Agency predicts that by 2050, Australia will require 6 gigatonnes per year of CCS storage, which is 100 times more than its current operational capacity. The agency also acknowledges Australia’s competitive advantage in CCS, highlighting its potential for large-scale deployment.

Santos is advancing its plans for decarbonisation and new fuel technologies by signing MOUs with strategic partners.
