No BECCS projects in Track 1 despite importance for unachievable 2030 greenhouse gas removal targets
Recommendation
The original 2030 targets for the CCUS programme, which the government has now told us are unachievable, included a goal for the UK to achieve 5 mtpa of engineered greenhouse gas removals. The bulk of this was expected to be …
Read more
Government Response Summary
The government agreed that any future support for BECCS will be accompanied by monitoring arrangements that provide real assurance that industry is meeting sustainability criteria, which will build on existing sustainability criteria for biomass, with target implementation in Summer 2025. The department plans to consult later this year on the development of a common biomass sustainability framework. An independent review will consider how Greenhouse Gas Removals (GGRs) can assist the UK in meeting the government’s net zero targets and ensuring security of supply, out to 2050.

Conclusion
Accepted
While the Department is taking steps to incentivise efficient delivery of the CCUS projects, it has not established mechanisms to make sure that taxpayers and consumers will benefit financially should the programme be successful. The Department has developed a range of business models for applying CCUS to a range of …
Government Response Summary
The government agrees, stating that existing business models already include mechanisms like a 'gainshare' in the Net Zero Teesside Dispatchable Power Agreement to ensure financial benefit for taxpayers and consumers. The Department will continue to evolve these models, working with the National Wealth Fund and Great British Energy.
3
Conclusion
Accepted
The Department and HM Treasury have yet to assess the full financial impact of the CCUS programme on taxpayers and consumers. The costs of the CCUS programme are significant: in November 2024 the government announced £21.7 billion of funding over 25 years to cover only the first five CCUS projects. …
Government Response Summary
The government agrees and states that it already assesses the affordability of CCUS support as part of key policy processes and Spending Reviews. It highlights that rigorous assessments, in line with Treasury Green Book principles, have already been undertaken for the initial phases of the East Coast and HyNet clusters, considering impacts on taxpayers and billpayers.
4
Conclusion
Accepted
The Department and HM Treasury lack clarity on how they would take account of project underperformance and advances in scientific understanding as part of their ongoing assessment of the programme’s future. The Department had a clear set of five factors it considered when assessing the value for money of the …
Government Response Summary
The government agrees and is taking several actions regarding BECCS, including developing new sustainability criteria for future support, planning a consultation on a common biomass sustainability framework, commissioning BSI to develop GGR methodologies by mid-2025, and launching an independent review into GGRs.
1
Conclusion
Accepted
On the basis of a report by the Comptroller and Auditor General, we took evidence from the Department for Energy Security and Net Zero (the Department) on its carbon capture, usage and storage programme.1
Government Response Summary
The government states it has already created business models to provide minimum subsidy, established a Cluster Sponsor Function to monitor progress and risks, and set up assurance and control mechanisms, including a new construction team with monthly reviews.
7
Conclusion
Not Addressed
A major factor in the failure of the second CCUS competition was the lack of agreement between the Department and HM Treasury on funding limits.15 The Department told us that this time it had agreed an affordability envelope with HM Treasury which has developed as the projects have matured.16 HM …
Government Response Summary
The government's response provides a general introduction to the CCUS programme, previous attempts to launch CCUS, the current approach, funding announcements and signed contracts with the first two projects. It does not directly address the conclusion about the Department and HM Treasury agreeing on funding limits.
8
Conclusion
Accepted
Significant risks to the successful implementation of CCUS technology remain. There are still no CCUS plants operating at a commercial scale in the UK and the technology is unproven at the scale being planned.20 For example, written evidence we received stated that there are currently only two power stations worldwide …
Government Response Summary
The department has created business models that provide the minimum subsidy required, keeps the allocation of costs and risks under review to reduce subsidy, has established assurance and control mechanisms, created a new construction team and finance lead, and will carry out monthly reviews reported via the Sponsor Function Board.
10
Conclusion
Acknowledged
The Department established business models on which to base its support for each of the projects in the programme’s Track 1.28 These models set out how costs and risks are distributed between the government and the project.29 The Department told us that it had separate business models for transport and …
