Carbon capture and storage is frequently presented as essential to achieving net zero. Capture emissions at source. Transport the CO₂. Store it underground. Decarbonise heavy industry without dismantling it. The concept is attractive in its simplicity.
The infrastructure required to deliver that simplicity is anything but simple. High-pressure pipelines, compression facilities, injection wells, monitoring systems and long-term regulatory oversight all need to function reliably for decades. The system only works if every link in the chain performs as intended.
The Institute for Energy Economics and Financial Analysis has consistently examined the gap between ambition and delivery within the carbon capture sector. Its work has highlighted cost overruns, underperformance and the risk of overstating carbon capture as a silver bullet while operational challenges persist. The concern is not only financial. It is structural and systemic.
In the context of CO₂ pipelines, incidents such as Satartia intersect directly with this wider critique. Rapid expansion of infrastructure under political and commercial pressure can lead to risk being framed as manageable without full transparency about potential consequences. Communities may be told that incidents are rare without being shown credible worst case scenarios.
MIT’s climate analysis acknowledges that while accidents may be infrequent, when high-pressure CO₂ systems fail, the consequences can be serious. Rapid decompression can release large volumes quickly. The affected zone depends on terrain, weather and operating conditions. It may extend beyond the narrow strip of land directly above the pipeline.
The central issue is balance. Climate ambition must be matched by operational realism. Dense phase CO₂ transport carries a distinct hazard profile. It demands robust inspection regimes, appropriate valve spacing, corrosion control, route selection sensitive to terrain and population density, and meaningful emergency planning with local responders.
Transparency is fundamental. Communities deserve to understand not just the climate case, but the infrastructure case. That includes credible modelling, clear communication of uncertainty and honest acknowledgement of what happens if containment fails.
Carbon capture may play a role in decarbonisation. That discussion is legitimate. What is not legitimate is minimising the specific risks associated with transporting compressed CO₂ over long distances. Infrastructure decisions made today will define community risk profiles for decades.
Enthusiasm should not outrun evidence. Build-out should not outrun safeguards. And reassurance should not replace rigorous analysis. If carbon capture is to be part of the future energy system, it must withstand scrutiny not only on emissions accounting, but on safety, resilience and transparency. People living along proposed routes deserve answers that stand up when tested, not simply when presented.
