Material Integrity of the Carbon Capture Storage Infrastructure

Abstract:
The worldwide climate change is caused by the increased greenhouse gas (GHG) concentration in the atmosphere. To achevie the Paris Agreements 1.5 °C pathway the GHG carbon dioixde (CO2) must be reduced. Therefore according to the UN’s Climate Panel IPCC, a crucial tool to achieving the Paris Agreement is Carbon Capture, Utilisation and Storage (CCUS) which would be challenging to achieve without. CCUS is a technology where the CO2 emissions are reduced by capturing the CO2 and storing it in a geological site or utilising it for green fuel production. However, the CO2 cannot be stored or utilised if there is no connection between the capture site and the storage or utilisation site. Three primary forms of transportation are by trucks, ships or through pipelines. Pipeline transportation is the main way of transporting CO2. However, impurities like H2O, H2S, NOx, and SOx can compromise the transportation and cause corrosion or scaling, leading to huge economic costs, underlining the need for proper pipeline material selection and monitoring of these impurities. Furthermore, it is desired to limit the need for purification of the CO2 without having the risk of corrosion, becoming a cost balance between material and purification cost.
This PhD project will study the material integrity of the Carbon Capture Storage transportation infrastructure, focusing on the impurities and their negative impacts on the transportation infrastructure. Additionally, measure corrosion and monitor the impurities inside the CO2 transport pipeline.
