To achieve the global climate goals, carbon capture, utilization, and storage (CCUS) technologies are essential for reducing greenhouse gas emissions from various sectors. A key component of CCUS is the development of reliable and efficient infrastructure for transporting carbon dioxide (CO₂) from emission sources to storage or utilization sites.

CO₂ transport infrastructure connects the different elements of CCUS, enabling the movement of captured CO₂ to locations where it can be permanently stored or used. Pipelines are the most common and cost-effective method of CO₂ transport, especially for large volumes and long distances. A robust technical framework for CO₂ pipeline systems is needed to support the transition to a low-carbon future.

Natural gas pipeline codes are well-developed and provide comprehensive guidance for the design, construction, operation, and maintenance of natural gas pipelines. However, there is a lack of codes specifically designed for CO₂ transport. Since natural gas and CO₂ pipelines have similar infrastructure and operational needs, existing natural gas codes can be used as a basis for adapting them to CO₂ transport applications. By revising and adjusting the requirements of established natural gas pipeline codes and considering the specific challenges of CO₂ transport the existing design code can be modified to ensure the reliability and safety of the pipeline system throughout its operational lifecycle. This approach makes use of the extensive knowledge and experience gained in the natural gas industry while ensuring that CO₂ transport infrastructure meets the required integrity and safety standards.
