Department and Treasury lack clarity on accounting for CCUS project underperformance and scientific advances
Conclusion
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 first two clusters and then the individual projects it selected as part of Track 1 of the programme. The Department and HM Treasury were also clear that projects would be subject to a further value for money assessment before awarding contracts. As part of this assessment it would consider the cost effectiveness of capturing carbon and wider economic issues such as investment in particular regions. But some recent scientific evidence suggests that producing liquid natural gas (which will be used to run several CCUS projects, such as Net Zero Teesside) leaks more methane, a potent greenhouse gas, into the atmosphere than previously thought. As CCUS will not reduce these ‘upstream’ emissions, this could undermine the rationale for pursuing certain projects. The government also expects bioenergy with carbon capture (BECCS) to play a significant role in providing negative emissions to offset residual emissions in other sectors. However, the National Audit Office has previously concluded that the government could not demonstrate the adequacy of monitoring arrangements for its existing schemes to support bioenergy in giving it confidence industry was meeting sustainability standards. In addition, Ofgem’s critical findings in its recent investigation on Drax (which has received more than £6 billion of public funding over the last two decades) over its approach to reporting against sustainability criteria, have raised concerns over whether BECCS offers a genuine path to reducing emissions. We are therefore concerned that any government support for BECCS at Drax will not necessarily support its net zero ambitions and are minded to examine further the issue soon. If not a
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.

HM Government
Accepted
The government agrees with the Committee’s recommendation. any future support for BECCS. These criteria will build on existing sustainability criteria for biomass and include associated monitoring, reporting and verification arrangements. The department plans to consult later this year on the development of a common biomass sustainability framework to ensure greater consistency between sectors and strengthen the criteria in line with latest evidence. In addition, in September 2024, the government commissioned the British Standards Institution to develop engineered Greenhouse Gas Removal (GGR) methodologies, including one covering BECCS. An initial version is due to be published mid-2025. Separately, an independent review will consider how Greenhouse Gas Removals (GGRs), including large-scale Power BECCS, can assist the UK in meeting the government’s net zero targets and ensuring security of supply, out to 2050. Further details of the review will be made public in due course.
