World’s First Liquid and Supercritical CO₂ (Dense Phase) Flow Measurement Facility Opens

TÜV SÜD National Engineering Laboratory recently completed the world’s first SI-traceable primary standard flow measurement facility for dense phase (liquid and supercritical) CO₂. Developed through the ENCASE Project and the Flow Programme, this pioneering centre is set to transform the accuracy and reliability of carbon capture, utilisation, and storage (CCUS) measurement across the industry. 

The new facility enables SI-traceable flow calibrations and advanced R&D testing for liquid and supercritical CO₂, ensuring that custody transfer flow meters and composition analysers deliver precise results. This is vital for maintaining confidence in the quantity and quality measurements that underpin government subsidies, regulations, and commercial contracts in the CCUS sector. 

TÜV SÜD’s Head of CCUS, Gabriele Chinello said: 

“We are proud to launch this facility which will play a crucial role in supporting the global transition to net zero. By providing the highest standards of measurement accuracy for CO₂, we are enabling industry and governments to meet their climate goals with confidence and transparency,” 

Equipped with a DN80, ANSI#1500 stainless steel closed loop system and flexible test sections, the facility supports a wide range of research, development, testing, calibration, and validation activities for OEMs, operators, and academia. It can handle pure CO₂ as well as CO₂ with impurities, at flow rates from 0.7 to 70 m³/h and pressures up to 200 bar.g. 

As the UK’s National Measurement Institute for Flow Measurement, TÜV SÜD National Engineering Laboratory continues to provide world-class technical advisory, research, and testing services to industries including oil & gas, water, power & energy, and government.
