The construction of the process plant required for carbon capture in power generation and also other industrial processes will be among the most significant capital investments of the next 20-30 years. The correct choice of materials for piping vessels and all types of equipment will be vital in ensuring the long-term performance safety and high operational availability of the capture plants through their lifetime. Controlling materials related costs will help enable a wider and faster roll-out of carbon capture systems. In general the carbon capture processes have so far only been operated on sub-commercial pilot-scale plants and for a relatively short period although there is much useful experience from other large-scale industrial processes with similar conditions However carbon capture processes do differ in some aspects which can be important for material performance and selection. This paper focuses on corrosion and materials degradation risks from the process streams and materials issues specific to the main proposed carbon capture processes (Post combustion Pre combustion (IGCC) and Oxy-fuel). Some specific corrosion issues and problems are discussed. Areas where potential problems exist or where further studies are required are highlighted.
