A recent analysis has cast a critical light on the true financial and environmental implications of the UK Government's carbon capture and storage (CCS) programme. While official government figures have indicated a cost of £21.7 billion for the programme's initial phase up to 2050, independent research suggests the total expenditure for the full programme could soar to an estimated £264 billion over the same period.
This substantially higher figure, derived from data produced by the government's Climate Change Committee and analysed by climate experts Dr Andrew Boswell and Simon Oldridge, raises significant questions about the programme's transparency and long-term viability. A considerable portion of these costs, potentially up to £198 billion, is anticipated to fall on UK households through additional levies on energy bills, according to an investigation by the House of Commons Public Accounts Committee. The remaining public costs, approximately 25%, would be directly covered by the government. Further uncosted commitments, such as a 'premium' for hydrogen produced by CCS for 15 years, could add tens of billions more.
Beyond the financial outlay, the article highlights concerns regarding the programme's effectiveness in reducing carbon emissions. Despite the government's portrayal of CCS as essential for decarbonisation, critics argue that the majority of planned CCS projects are linked to new fossil fuel-burning power stations, wood-burning power stations, and hydrogen production from fossil gas. The Climate Change Committee's assertion that CCS is limited to sectors with few alternatives is challenged, with data suggesting only 5-6% of deployment will address emissions from hard-to-abate industrial sectors like chemicals and cement.
The article suggests that rather than cutting emissions, the programme could lead to a significant increase in gas consumption, particularly liquefied natural gas (LNG) imports. This is problematic as methane leakage during LNG production and transport means it can have higher emissions than coal before reaching the UK. Critics argue that a genuine focus on emission reduction would prioritise scaling up renewable energy and battery storage, which could lead to lower climate impacts and reduced energy bills.
The direction of the CCS programme has also drawn scrutiny regarding potential influence from the fossil fuel industry. In 2023, oil companies Equinor, BP, and ExxonMobil reportedly held 24 meetings with Conservative ministers to discuss CCS, coinciding with key decisions on deployment. This has led to suggestions that the programme may serve to allow continued burning of gas rather than facilitating a rapid transition away from fossil fuels.
The Labour Party has previously expressed support for CCS in certain industrial clusters but has also emphasised the importance of ensuring value for money and genuine emission reductions. The Liberal Democrats have been more critical, often advocating for greater investment in established renewable technologies. This debate underscores a broader political divergence on the most effective and economically sound strategies for achieving the UK's net-zero targets.
