3-P6 CarbonAdapt

The adaption of existing infrastructure for CO2 storage in reservoirs 

Transportation and injection of captured CO2 is an essential part in any CCUS strategy. However, corrosion in pipelines can have a huge economic impact on the pipeline infrastructure for CO2 injection if care is not taken. In the worst case, corrosion can reduce the wall thickness to such a degree that the pipeline will crack in the corroded area causing uncontrolled leaks or damage to the entire pipeline system.

The transportation pipelines and injection wells will play a key role as the connection between carbon capture utilization and storage why it is essential to assess the impact of CO2 on current oil and gas infrastructure or installation of new ones for CO2 applications, detailed knowledge of the interaction between CO2 (liquid or supercritical), impurities (e.g., water, H2S, NOx), process conditions, reservoir fluids, and the pipeline material is required and currently insufficient.

The project will investigate the corrosion effect of liquid or supercritical CO2 in the presence of impurities and provide a mathematical model to predict this corrosion on existing and new infrastructure. Moreover, the best available technology to measure impurities in a CO2 liquid environment will be investigated.

The project will provide fundamental and necessary information to frame future quality guidance and legislation for CO2 injection, which is currently lacking. In addition, a gap analysis will frame the material integrity and legislation for qualifying existing offshore facilities for CO2 injection.

  1. Examine possible CO2 impurity monitoring systems, both sample-based (off-line or at-line) and in-line measurements.
  2. Establish a relationship between the CO2 impurities and material corrosion in the pipelines/wells and associated equipment.
