UK cuts £200m from Acorn carbon capture grant funding

By Rebecca Stone

The UK government has cut £200 million ($269 million) from capital grants for carbon capture, utilization and storage in its latest Budget, leaving the Acorn carbon capture and storage project in St Fergus, Scotland, without confirmed grant funding.

The reduction reallocates resources toward defense expenditure. Its project-level consequence falls on Acorn, which lost direct capital support while grant funding remained protected for four designated deployment areas.

What changed in the Budget?

Grant funding remains protected for industrial clusters in Teesside, Merseyside and North Wales, plus the Viking project in the Humber. Acorn did not receive the same confirmation, despite previously being presented as a leading Scottish industrial decarbonization project.

Ministers said they are examining three alternative routes for Acorn:

• Alternative private investment
• Public loans
• Equity co-investments

The options remain under examination rather than committed financing. Ministers indicated that one or more could support the project’s long-term commercial structure, but no replacement package was confirmed in the Budget.

What does the funding gap mean for St Fergus?

The decision reverses the direction of policy assurances provided in June 2025. For Acorn, the reversal resembles a financing reset rather than a routine budget adjustment: the capital grant is absent, and no replacement structure has been defined.

The Budget announcement provides no plant capacity or operating date for Acorn. Its operational timeline remains unresolved, preventing the project from being treated as an operating asset with a settled delivery schedule.

Acorn is described as north-east Scotland’s primary industrial decarbonization anchor. For the captured-carbon-dioxide value chain at St Fergus, the immediate obstacle is now a missing financing commitment rather than a stated processing target.

Regional business leaders and energy stakeholders warned that the omission could weaken investor confidence in Scotland’s wider decarbonization pipeline. North Sea employers also face uncertainty over whether engineering work and associated supply-chain activity will continue on the expected timetable.

Why did industry groups object?

Russell Borthwick, chief executive of the Aberdeen & Grampian Chamber of Commerce, called the decision "a setback for North Sea supply chains and energy transition efforts." He said clear project commitments are needed to safeguard engineering jobs and maintain momentum across subsea and offshore wind infrastructure.

MHA tax and advisory experts said "the absence of a defined replacement financing structure creates uncertainty for private capital allocations across regional supply chains." That concern applies to companies deciding whether to commit staff, technical capacity or capital to projects tied to Acorn.

Construction and engineering executives from BAM UK & Ireland and AECOM said broader national infrastructure targets remain ambitious. Without immediate delivery plans for key industrial assets, they warned, workforce development, apprenticeship funding and private-sector co-investment could all slow.

The funding change also sits alongside two separate CCUS developments cited in the sector discussion. Storegga is set to pull out of Acorn, while BOC has commissioned a carbon capture facility at Teesside to strengthen the UK’s carbon dioxide supply. Neither development provides Acorn with replacement finance.

What must happen before Acorn proceeds?

Industry attention is shifting toward the government’s upcoming 10-year infrastructure strategy. Stakeholders expect it to explain how the National Wealth Fund and regional devolution frameworks could mobilize private capital for deferred energy-transition assets.

The strategy does not guarantee support for Acorn. Any contribution from the National Wealth Fund, devolved bodies or private investors would still need to form part of a defined commercial financing structure capable of supporting St Fergus.

The next decisive milestone is therefore the 10-year infrastructure strategy and a defined replacement financing package for Acorn. Until ministers identify whether private investment, public loans or equity will carry the project, it has no confirmed grant, no stated operating date and no settled commercial structure.
