To develop a sustainable CCS value chain, it is essential to focus on both new pipeline projects and the use of existing infrastructure. As the sector matures and experiences are gained through R&D and projects, it is crucial to keep industry standards up-to-date and aligned with the latest knowledge to tackle challenges quickly. The CO2SafePipe JIP was initiated in September 2023 by DNV with more than 20 participants. The JIP aims to collect industry best practices, close knowledge gaps, and provide guidance on pipeline system design, safety, operability, and transport capacity. The ultimate goal is to update DNV’s Recommended Practice RP-F104 ‘Design and operation of carbon dioxide pipelines.’
One of the critical decisions for CO2 pipeline systems is whether to transport the product in gaseous or dense phase. It is acknowledged that the criteria for documenting fracture arrest differ between gaseous and dense phase, considering possible variations in CO2 compositions and the effect on the CO2-decompression curve. Arresting running ductile fractures in pipelines transporting CO2 has proven to be more challenging than in transporting natural gas, and many pipelines fall outside the applicability range of the requirements laid out in DNV-RP-F104.
Another topic is the CO2 composition. Cleaning the CO2 from various industry emitters comes with a cost, so it is desirable to limit the need for cleaning harmful impurity elements by keeping its composition as wide as possible without jeopardizing the risk of corrosion and material degradation.
The status of the JIP will be presented.
>25 years of experience within the field of failure analyses, materials technology, pipelines. Main focus on CO2 and H2 the last years.
