As ExxonMobil Australia steps up decommissioning of ageing offshore oil and gas assets in the Gippsland Basin, the company is also repurposing onshore infrastructure as part of its ongoing energy transition and forward investment plans.
That includes the demolition of the former Altona refinery facilities, which Mobil commenced in September.
Rhys Kelly, Terminal Manager, Melbourne Terminal, said in an update that this decommissioning work would continue for two more years.
“Demolition of former refinery infrastructure is a complex task,” he noted. “Work commenced in September 2025 and is expected to continue through to the end of 2027.”
It follows a review of future opportunities for parts of the Altona Terminal site which are not required for fuel terminal operations.
Following the review, the company is planning to demolish a number of tanks, former refinery process units and associated infrastructure that are not required to support its vision for a reliable supply of fuel to Victoria.
Since works to transition the Altona site to a world-class terminal began in 2021, it has refurbished a number of tanks, increasing fuel storage capacity by almost 250 million litres to ensure it can meet the federal government’s minimum fuel storage requirements, as well as maintain a vital role in supplying around 40% of Victoria’s fuel needs.
“This year, we continue to focus on delivering additional fuel storage across the Mobil Melbourne terminal, including at Gellibrand Wharf and the Altona site, so that we can maintain our supply of around 40% of Victoria’s fuel from Melbourne’s largest fuel storage and distribution terminal,” added Kelly.
“It has been a productive year, and we have completed many projects that will provide the additional storage required to support our ongoing, reliable supply of fuel to Victoria into the future.”
In a community bulletin, Mobil added that it had carefully planned the demolition work to ensure it is managed safely.
Given the nature of the work, it said there may be “noticeable changes” in the site profile, with the flare being one of the first assets to be removed.
Mobil added that it will also implement strict environmental controls to minimise impact on the neighbourhood, including completing most work during the day, industrial hygiene monitoring and using dust suppression.
“We have worked closely with regulators to obtain the necessary approvals and carefully planned the demolition works to minimise impacts on our neighbours,” said Kelly.
“We will also closely monitor the works so that we can quickly respond to any unexpected impacts if they occur.”
The United Kingdom has witnessed the successful drilling of the country's first carbon storage appraisal well as part of its ambitious carbon capture and storage objectives.
According to Offshore Energies UK, this new well in the decommissioned Hewett gas field off Bacton on the coast of North Norfolk, will play a significant role in accelerating the path to net zero greenhouse gas emissions as it serves as a major carbon store in the region. The project reflects the UK industry's sustainable approach as it repurposes existing oil and gas infrastructure, delivering carbon capture and storage with the help of efficient supply chains and skilled workforce.
The site operated by the global energy company Eni, is part of the North Sea Transition Authority’s first carbon storage licencing round.
Powering the UK with gas for decades, the Hewett field will now boast a storage capacity of up to 10 million tonnes of CO2 annually as a large-scale carbon storage facility. This equals the yearly greenhouse gas emissions of around a fifth of all UK industry.
The location of Hewett is particularly well placed to support the decarbonisation of industry in Southern England and also industrial greenhouse gas producers in continental Europe.
With an aim to accelerate this process, Offshore Energies UK has initiated a round table with the European Commission, looking to navigate regulatory barriers that currently prevent cross border transport of carbon emissions.
The North Sea Transition Authority which oversees Britain’s carbon capture plans, has already awarded permits for the UK’s first two carbon storage projects. These are the Northern Endurance Partnership off Teesside in December 2024, and Liverpool Bay carbon capture and storage project in April 2025, which is also operated by Eni.
These two projects together could store more than 200 million tonnes of CO2, equivalent to taking 110 million cars off the road for a year. The permits have also unlocked £6bn worth of supply chain contracts and 4,000 construction jobs.
Enrique Cornejo, OEUK Head of Energy Policy, said, “This Hewett appraisal well is a powerful signal of industry’s commitment to invest in the UK’s net zero future. It shows how our existing energy infrastructure and expertise are being repurposed to deliver climate solutions. But for commercial carbon capture and storage to succeed at scale, government must accelerate a clear route to market for projects like Bacton CCS which are outside the government’s planned cluster sequencing process. The Hewett appraisal well is a tangible example of industry stepping up, and now it’s time for policy to keep pace.”
