Carbon capture and storage may be considered as a short- to medium-term solution while carbon-neutral energy technologies are developed. Recent developments enable capturing carbon in power generating plants as viable transporting it through pipelines as feasible and storing carbon underground as safe and ecologically sound. Several pilot plants have been built to optimize carbon capture and storage facilities and some experience has also been gained in transporting CO2. With all these developments carbon capture transportation and storage (CCS) network is being increasingly promising and becoming realistic. The CO2 being captured from the power plant may contain many impurities depending on the process and capture technologies. Currently there is not much knowledge on the effects of impurities on material properties. In this paper results obtained from experiments carried out in unique CO2 flow loop and laboratory apparatus on the influence of impurities (including O2 N2 SO2 NOx H2S ethylene glycol amines and ammonia) on the corrosivity of CO2 under capture (high temperature and high pressure) pipeline transporting (dense phase) and storage (high pressure) conditions will be presented. Corrosion products from the CO2 flow loop will be analyzed and correlated with the process conditions.
