The European Green Deal states that "energy storage and carbon capture, storage and utilization” is one of the priority areas to reduce greenhouse gas emissions of 55 % by 2030 and to become carbon neutral by 2050.

The project has received funding from the European Partnership on Metrology, co-financed by European Union Horizon Europe Research and Innovation Programme and from the Participating States.

Report: Results of analyser comparison in measuring CO₂ impurities: H2O (Endress + Hauser J22 TDLAS gas analyser and MEECO AquaVolt 2™ moisture analyser) and O2 (Endress + Hauser OXY5500 Optical Oxygen Analyzer)

Summary


This report presents the results of a round-robin comparison performed as part of activity A3.3.4 from the Partnership on Metrology project “Metrology for the support for Carbon Capture Utilisation and Storage” (MetCCUS). This work is focusing on the performance evaluation of three commercial analysers, the Endress Hauser J22 TDLAS and the MEECO AquaVolt 2 for measuring water (H2O) impurities in carbon dioxide (CO2) and the Endress + Hauser Oxy5500 analyser for oxygen (O2). All analysers were tested with calibration gas mixtures in the range of 5 μmol mol-1 to 60 μmol mol-1 H2O or O2, relevant to carbon capture, usage, and storage (CCUS). The report details performance parameters including response time, precision, bias, linearity, detection limits, and measurement uncertainty.

These findings support instrument manufacturers in demonstrating the fitness of their equipment for CO₂ composition monitoring, while also supplying valuable data that can be used to refine and advance technologies for more accurate CO₂ analysis in the future.
