Based on the knowledge accumulated in the past decade related to Carbon Capture and Storage (CCS) processes, and the identified gaps in knowledge, ICMT has decided to initiate a new program in the form of a Joint Industry Project (JIP) open to any company interested in corrosion issues for CO₂ transmission pipelines and related infrastructure. The overall objective of the proposed CCT JIP project is to identify and quantify the key issues which impact corrosion of materials specifically relating to the integrity of structures for the CO₂ transport pipelines. The result of this research will form a basis for more reliable design and operational decisions related to the adequate utilization of materials in CO₂ transportation. This will involve achieving four goals:

• To understand the effect of a wide range of impurities (O₂, SO₂, NO₂, H₂S, etc.) on the water solubility and the speciation in dense phase CO₂.
• To develop a thermodynamic model for predicting the water solubility and the speciation in dense phase CO₂ in the presence of impurities.
• To determine impact of environmental parameters (pressure, temperature, flow, and impurity types and concentrations), both individually and synergistically, on steel corrosion in dense phase CO2 in the presence of impurities.
• To develop a mechanistic model to predict the corrosion processes in order to help determine facility lifetime.

The target start date for the project is January 2023 and the total duration of the project is 3 years. The JIP will be guided and supervised by Professor Srdjan Nesic (Director ICMT), Dr. Yoon-Seok Choi (Associate Director ICMT) and Professor Sumit Sharma (Associate Professor at the ChBE department).
