Carbon capture and storage or carbon capture and utilisation (CCS or CCU) are being considered in order to facilitate the extended use of both fossil-fuel power stations and high carbon dioxide (CO2) emitting industrial facilities such as steel, cement and petrochemical plants. In order to realise such anthropogenic CO2 abatement strategies, it is vital to ensure that the CCS/CCU chain provides solutions for the transmission of CO2 from the point of capture to the location of permanent storage or transformation. Provision of a safe, reliable and cost-effective transportation network for CO2 is a key pre-requisite of all CSS innovations. The research into materials selection is important as a cheaper, yet satisfactory material could make the difference between technology acceptance and failure. The test protocols are also important as incorrect simulation of environment could lead to the selection of unsuitable material. The paper focuses on these aspects and brings to light some understanding gained during the material selection process. The important aspect related to the test protocol is discussed and results on some selected materials are also presented.
