From Lab to Trench: CO₂ Pipeline Engineering Takes Center Stage
On March 18, 2026, London will host the first CCS Forum organized by World Pipelines, an event marking a significant shift in the debate on carbon capture and storage (CCS) in the UK.
Until now, public conversation has been dominated by political ambition and major industrial announcements. This forum, however, descends to the technical ground where the battle is truly won or lost: the design, construction, and operation of CO₂ pipeline networks.
The timing is no coincidence. Track 1 industrial clusters—the British government’s first priority CCS projects—have passed financial close and are now entering the construction phase. It is precisely in this transition where engineering decisions stop being theoretical and become steel, welds, and miles of underground pipeline.
Technical Challenges Defining the Success or Failure of British CCS
The forum program has been structured around four axes that industry engineers consider critical: design of supercritical CO₂ pipelines, selection of materials resistant to corrosion and brittle fracture, long-term operational integrity, and planning for modular network expansion.
El CO₂ transportado en fase densa (estado super-crítico) se comporta de forma radicalmente distinta al gas natural. Su alta densidad exige presiones de operación elevadas, mientras que la presencia de impurezas como H₂S, SOx o agua puede desencadenar mecanismos de corrosión que inutilizan el acero en años, no décadas.
Another aspect rarely discussed publicly, but central to operators, is the phenomenon of ‘running ductile fracture’ (RDF): a catastrophic failure that can travel hundreds of meters of pipeline in seconds if the material is not correctly specified for CO₂ conditions.
Designing Today the CO₂ Pipeline Network That Will Sustain Tomorrow’s Climate
The most strategic aspect of the forum—and what differentiates this event from a simple technical meeting—is its focus on long-term network architecture. The UK is not building a CCS project; it is attempting to build a system.
The difference is crucial: a project is optimized for its current conditions, a system is designed to be expanded, interconnected, and adapted to new emission sources.
The decisions made today about pipeline diameter, location of compression stations, and interconnection nodes will determine whether the UK’s CO₂ pipeline network can scale economically over the next decade, or whether each new connection will require major works.
The question posed by the event itself summarizes it with technical precision and political urgency: how do we design today’s clusters to enable a resilient CO₂ network for tomorrow? The answer, to a large extent, will begin to be written on March 18 in London.
