The limitations of carbon capture as a climate strategy
Top line
Critics argue that carbon capture serves as a justification for ongoing fossil fuel expansion, advocating instead for a rapid transition to a 100% renewable energy system.
Summary
Contributors Andrew Boswell and Simon Oldridge argue that carbon capture and storage (CCS) functions as a strategic 'fig leaf' to justify continued fossil fuel expansion rather than a genuine climate solution. Boswell highlights that current CCS proposals ignore the significant climate impact of methane leakage and that the high costs associated with CCS are disproportionate to the small amount of emissions captured, especially when compared to the vast impact of rapid renewable energy deployment. Oldridge further criticizes the CCS industry for prioritizing new gas infrastructure over genuine industrial decarbonization, noting that public subsidies are being directed toward projects that maintain the UK's dependency on imported gas. Both authors advocate for a shift toward a 100% renewable energy system as a more viable and cost-effective path to climate stability.
Highlights
- Andrew Boswell critiques the proposal to link gasfield licensing to carbon storage, noting it ignores methane emissions occurring throughout fossil fuel supply chains.
- Methane emissions are identified as a dominant near-term climate impact, particularly in liquefied natural gas (LNG) operations.
- The projected cost of CCS in the UK is estimated at £264 billion by 2050, a figure Boswell suggests may be conservative given the gap between current project capacity and the Carbon Capture and Storage Association's pipeline.
- Data from the International Energy Agency indicates that wind and solar energy avoided 2,600 megatonnes of CO2 in 2025, compared to less than 40 megatonnes captured globally by CCS.
- CCS infrastructure projects are criticized for providing significant temporary construction employment while failing to generate substantial long-term operational jobs despite long-term taxpayer subsidies.
- Simon Oldridge contends that the Carbon Capture and Storage Association (CCSA) misrepresents the scope of CCS, which is primarily focused on new gas power stations rather than 'hard-to-abate' industrial sectors.
- The majority of UK CCS funding is allegedly directed toward new fossil gas hydrogen and power generation, which increases demand for imported LNG and locks in upstream methane emissions.
- Oldridge argues that a 100% renewable energy system is technically feasible and represents a more cost-effective strategy than expanding fossil fuel reliance through CCS.
- Nature restoration is proposed as a viable, cost-effective alternative for handling residual carbon emissions while providing ecological and public health benefits.
