Introduce mechanisms for taxpayers and consumers to benefit financially from future CCUS project success
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 … Read more
Government Response
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.

Assess the full CCUS programme's affordability for taxpayers and consumers amid cost of living pressures
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 … Read more
Government Response
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.

8th Report - Carbon Capture, Usage…
Set out rationale for supporting CCUS in each sector, considering cost-effective alternatives
To date, the Department has done little to ensure that government support for CCUS is directed to the sectors or locations where it will be essential for achieving net zero. CCUS is currently seen as the only way to decarbonise … Read more
Government Response
The government agrees, stating the recommendation has been implemented as the Department already sets out its rationale for supporting CCUS in various sectoral strategies and compares costs with alternative approaches to achieve net zero. It ensures resources are allocated to sectors with few alternatives and where CCUS is cost-effective.

6 Recommendation Accepted
8th Report - Carbon Capture, Usage…
Set out urgent new carbon capture targets and clarify how to address net zero shortfall
The Department has downgraded its ambitions for the CCUS programme, stating that the original 2030 ambitions are no longer achievable. The current CCUS programme is the government’s third attempt to introduce the technology. Compared with previous attempts, the government is … Read more
Government Response
The government agrees and outlines its plan to monitor and report on net carbon captured by CCUS projects once operations begin, detailing obligations for Transport & Storage Companies and capture projects to report capture rates, storage performance, and leakage to relevant regulators. It has also established a Cluster Sponsor Function for performance oversight.

Committee receives evidence on Department's carbon capture, usage and storage programme
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
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.

8th Report - Carbon Capture, Usage…
Significant risks and unproven technology hinder successful CCUS implementation at commercial scale
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 … Read more
Government Response
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.

Department lacks clear plan for government to share in successful CCUS project profits
We asked the Department whether its business models allow for the government to take a share of any profit a project makes if the programme is successful.37 But the Department could not provide a compelling answer.38 Now that the Department … Read more
Government Response
The department will continue to evolve business models including mechanisms to ensure taxpayers and consumers benefit financially from the success of CCUS projects, including gainshare, and will work with the National Wealth Fund and Great British Energy to support delivery and drive value for money, with a target implementation date of December 2026.

Concerns raised about CCUS effectiveness and unaddressed methane leakage from LNG supply chains
The Department recognised that there are some “contested views” concerning, for example, the effectiveness of CCUS in reducing emissions from gas–fired power stations.69 We received written evidence suggesting that there are higher levels of methane (a gas with significant greenhouse … Read more
Government Response
The government will reappraise on an annual basis its approach to assessing the value for money of CCUS projects, considering the impact of up-to-date scientific understanding. This appraisal has been implemented since the start of the CCUS programme and was implemented most recently via Full Business Cases in Summer 2024.

No BECCS projects in Track 1 despite importance for unachievable 2030 greenhouse gas removal targets
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
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.

CCUS remains only viable decarbonisation method for specific industrial process emissions
At present, CCUS technology is the only way to decarbonise industries that generate emissions from physical or chemical processes, rather than from the combustion of fuels. For example, 60 to 70% of emissions from the cement industry come from chemical … Read more
Government Response
The government agreed to set out its rationale for supporting CCUS in each sector where it could be applied, including considering whether alternative approaches could be more cost effective, referencing various sectoral strategies and analysis. Separately, 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.
