Carbon Capture and Storage (CCS) will have to turn into a massive industry in order to play a significant role in the mitigation of anthropogenic climate change. The EU Emissions Trading Scheme (ETS) directive establishes that emissions captured, transported, and stored are considered as ‘not...

New data are presented for the thermal conductivity for CO2-rich binary mixtures in the liquid and dense phase, for temperatures between 223 and 308 K and pressures up to 20 MPa. Binary mixtures with mole fractions of 5% nitrogen and 5, 10, and 20% methane were investigated. Understanding the fluid...

The design of safe and cost-efficient CO2-transportation systems is an integral part of CO2 capture and storage (CCS) deployment. To achieve this, accurate transient flow models capturing the occurrence of gas, liquid and solid CO2 are needed. These in turn rely on experimental validation. In this...
