Storegga, the lead developer behind the ambitious Acorn carbon capture and storage (CCS) project in Aberdeenshire, Scotland, has announced its intention to divest its interest in the venture. This decision follows a comprehensive strategic review of the company’s business, capital requirements, and future structure. The move introduces uncertainty for a project deemed critical to the UK’s net-zero ambitions, even as the government reaffirms its commitment with a £200 million investment.
The Acorn project, situated at the St Fergus gas terminal, aims to establish a hub for capturing industrial carbon emissions across Scotland and permanently storing them beneath the North Sea. It leverages existing pipeline infrastructure, with plans to repurpose 175 miles of gas pipelines and construct an additional 35 miles of new infrastructure to link industrial emitters in regions like Grangemouth, Peterhead, and Mossmorran to offshore storage sites. Acorn is a joint venture involving Storegga, Shell UK, Harbour Energy, and North Sea Midstream Partners.
The UK Government maintains its unwavering support for the initiative. A spokesperson commented: “This is a commercial decision for Storegga Ltd. UK Government remains committed to the Acorn project.”
In Case You Missed it:
Despite its critical role, the CCS sector in the UK has a “turbulent history,” marked by previous funding cancellations that have eroded investor confidence. Challenges persist, including the substantial capital costs of projects and difficulties in securing private investment, partly because the current carbon price does not make CCS financially viable for many industrial sectors. Industry leaders, such as Sir Ian Wood, Chair of ETZ Ltd, have expressed “deep concern” over Storegga’s departure, urging both the UK and Scottish governments to ensure the future of Scotland’s sole Carbon Capture Cluster.
While Storegga seeks a new owner for its stake, work on the project is expected to continue to maintain momentum. The search for a new long-term owner will be crucial in advancing Acorn towards its operational phase, ensuring that the UK can leverage this vital technology in its pursuit of net-zero emissions.
