DNV project launched for CO2 flow meter traceability

DNV, the independent energy expert and assurance provider, has initiated CO2MET, a joint industry project (JIP) to establish traceable flow standards for CCUS

The project brings toegether equipment suppliers, major transmission system operators and exploration and production companies.

As demonstrated by a DNV study, there are currently significant gaps in demonstrating compliance with CO2 metrology for the EU Emissions Trading System (ETS) and other international regulations, with two significant challenges being the absence of an officially recognised and traceable standard for measuring CO2 volume under dynamic conditions for gas, liquid, and dense phase CO2; and the lack of flow laboratories conducting research and calibrations under the necessary process conditions.

The JIP is divided into two initiatives:
1. CO2MET Gas: Centered around gas applications, this project is expected to conclude in June 2024.
2. CO2MET LIQ: Focusing on conditions related to liquid, dense, and supercritical CO2, this project requires the design and construction of a new facility at DNV’s Technology Centre in Groningen to enable the development of traceable flow standards. First results are anticipated by the end of 2024, with current participants including Shell, TotalEnergies, Equinor, Gasunie, Santos, Inpex, and Gassco. New participants are welcome to join.

"As the world advances towards decarbonisation, DNV is proud to lead the establishment of essential standards for CO2 metering to ensure the global success of CCUS initiatives. By convening industry stakeholders to develop trusted guidelines, recommended practices, and standards, we ensure the reliable operation of critical assets and systems. This involves setting operational limits and ensuring performance throughout the lifespan of industrial assets," explained Prajeev Rasiah, executive vice president and regional director Northern Europe, Energy Systems at DNV.

“DNV’s Technology Centre in Groningen plays a pivotal role in tackling the challenges of CO2 flow metrology to advance projects related to CCUS," added Rene Bahlmann, head of Section for DNV's Technology Centre Groningen, Energy Systems at DNV.
