CLUSTER - Impacts of impurities in CO₂ streams captured from different emitters in a regional cluster on transport, injection and storage

Key questions: How pure do CO₂ streams have to be for accessing larger CO₂ pipeline networks and which aspects other than CO₂ stream composition need to be considered to ensure safe transport, injection and storage operation with technically and economically acceptable efforts?

These are the key questions that the project CLUSTER aimed to answer.

More specifically, the project partners were investigating:

i) potential impacts of temporal variations in CO₂ stream composition and mass flux that occur in larger pipeline networks on transport, injection and geological storage of CO₂;

ii) flexibility of individual steps and the whole CCS process chain in response to this temporal variability.

Overall, we established recommendations how to define "minimum composition thresholds" that CO₂ streams must meet according to EU Directive 2009/31/EC when accessing a shared transport and storage infrastructure.
