DNV’s ‘Skylark’ Study Targets Safer CO₂-Pipeline Expansion
(P&GJ) — DNV has kicked off a three-year research program called Skylark to generate real-world data on carbon-dioxide pipeline safety—information regulators say they need before approving large-scale carbon-capture networks.
Developed with the UK Health and Safety Executive’s Science Division, the University of Arkansas, Ricardo’s National Chemical Emergency Centre, the National Centre for Atmospheric Science and Britain’s Department for Energy Security and Net Zero, the joint-industry project will combine full-scale rupture tests at DNV’s Spadeadam facility with wind-tunnel and dispersion modelling.
The aim: predict how dense CO₂ behaves if a pipeline ruptures across varied terrain and weather, and test emergency-response drills with first responders.
“Skylark addresses one of the biggest barriers to CCS adoption—confidence in safe operations at scale,” said Hari Vamadevan, senior vice-president for DNV Energy Systems in the UK & Ireland. The results will feed directly into updated safety guidelines for pipeline routing, venting and risk assessment, he added.
DNV’s latest Energy Transition Outlook estimates that global CO₂ pipeline mileage must jump from about 9,500 km today to more than 200,000 km by 2050 to hit net-zero targets. Nine companies have already joined the project; DNV is seeking more participants before large-scale field trials begin in 2025.
“CCUS will be a critical tool in delivering on our net-zero commitments … Initiatives like Skylark will be a vital tool in ensuring the success of this technology,” said Paul Monks, chief scientific adviser at the Department for Energy Security and Net Zero.
