Join Our New Supercritical CO2 Transport Project

Tue, 25 July, 2023

We are launching a new joint industry project (JIP) dedicated to the topic of ‘Materials Assessment for Supercritical CO2 Transport (MASCO2T II).’

Carbon capture and storage (CCS) is vital for industries that are working to reduce CO2 emissions. An important aspect of this is pipeline transportation, which provides a safe and affordable option for moving large volumes of CO2. In order to maximise the rate of transport the CO2 is typically pressurised to become a liquid or supercritical fluid.

However, the CO2 transported from CCS is likely to be impure and contain contaminants such as H2O, NOx, or H2S. The presence of oxides and nitrogen can lead to the formation of nitrous and nitric acids that increase the corrosivity of the fluid beyond the levels usually experienced in conventional CO2 transport pipelines. This can lead to cracking, while the interaction between the components in these complex environments is not well understood.

This project will generate the data required for material selection for new build design and re-rating of existing metallic components in contact with supercritical CO2, with impurities. This will, in turn, provide increased confidence in material selection, reduce the possibility of pipeline failure and the subsequent associated downtimes, as well as contributing to the development of standards for materials for transporting impure CO2.

Why Join the JIP?

Those who join the JIP will not only be able to guide the direction of the research but will also gain access to the confidential information that is generated. The project will allow you to share knowledge with other interested parties as well as giving you access to TWI’s independent expertise and world-class research capabilities.

While the project will provide you with access to exclusive, industry-changing research that can advance your operations and save costs, you will see more results from joint sponsorship of the project by pooling your resources with other interested parties than you would by investing on your own.
