Wintershall tests CO₂ in subsea gas pipes

Existing offshore pipelines could be suited to transporting liquid CO₂, gas producer says

Natural gas producer Wintershall Noordzee has launched the world’s first large-scale project to explore the use of existing subsea natural gas pipelines to transport liquid CO₂. The firm is working with risk management company DNV and OTH Regensburg University of Applied Sciences to establish the likelihood of subsea pipes cracking if they were used to transport CO₂. The results will be compared with those from similar tests on pipelines in the open air. "Our calculations already show that existing offshore pipelines could be well suited for transporting liquid CO₂. The next step will be to demonstrate the reliability of the evaluation process and prove the feasibility experimentally,” says
