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.

D7 – Paper on the measurement of the thermophysical properties of CO2mixtures for CCUS (with target uncertainties: for density better than 0.1%, for specific heat capacity better than 1 %, for viscosity less than 3 %, for speed of sound in liquid better than 0.05 %, for gas phase at hightemperature 0.03 %) submitted to an open-access peer-reviewed journal

Accurate knowledge of the thermophysical properties of CO2-rich systems is crucial for ensuring the successful deployment of CCUS technologies across Europe. Understanding the thermophysical properties of carbon dioxide mixtures with a range of potential impurities reveals gaps between the experimental data
required for the systems design and operation.


In this context, key experimental properties were measured for CO2 + monoethanolamine and CO2 + diethanolamine binary mixtures, supporting the development of more refined and accurate formulations for dedicated equations of state.
