Research momentum for the CCUS deployment is growing globally driven by the climate goals and a more attractive investment environment. The availability of infrastructure to transport and utilize CO2 safely and reliably is essential for the deployment of CCUS. One major issue in delaying the CCUS implementation is the corrosion of materials of constructions (MOC) caused by water and other impurities under supercritical CO2 (S-CO2) conditions. Steels are the primary MOC in CCUS-EOR systems and are susceptible to corrosion in S-CO2 environments because of the presence of H2O, O2, SOx, H2S, and NOx. Hundreds of research papers have focused on studying the corrosion of steels under S-CO2 conditions in the past decades. Although extensive research activities have been done and are still on-going, most of them are done by isolated research groups and cannot be effectively and or efficiently contribute to the development of universal CO2 impurity and MOC selection standards. The complexity of the investigated corrosive environments and the diversity of as-obtained data make it highly challenging to develop practical operation standards for CCUS industries. The long-term goal of this research program is to promote the implementation of CCUS-EOR technologies in the Canadian energy sectors. To achieve this, two specific tasks are proposed: 1) a data-oriented review covering the existing corrosion data of steels in CCUS-EOR under S-CO2 conditions, factors which have been overlooked, and contradictory conclusions which are worth re-evaluating; 2) corrosion assessment of various MOCs in simulated formation water for CO2-EOR applications.

在气候目标和更具吸引力的投资环境的推动下，全球 CCUS 部署的研究动力正在不断增长。安全可靠地运输和利用二氧化碳的基础设施的可用性对于 CCUS 的部署至关重要。推迟CCUS实施的一个主要问题是超临界二氧化碳（S-CO2）条件下水和其他杂质引起的结构材料（MOC）腐蚀。钢是 CCUS-EOR 系统中的主要 MOC，由于存在 H2O、O2、SOx、H2S 和 NOx，因此在 S-CO2 环境中容易腐蚀。过去几十年来，数百篇研究论文重点研究了 S-CO2 条件下钢的腐蚀。尽管广泛的研究活动已经完成并且仍在进行中，但其中大多数是由孤立的研究小组完成的，不能有效地和或高效地为通用 CO2 杂质和 MOC 选择标准的制定做出贡献。所调查的腐蚀环境的复杂性和所获得数据的多样性使得制定 CCUS 行业的实际操作标准极具挑战性。 该研究计划的长期目标是促进CCUS-EOR技术在加拿大能源领域的实施。为了实现这一目标，提出了两个具体任务：1）以数据为导向的审查，涵盖S-CO2条件下CCUS-EOR中钢材的现有腐蚀数据、被忽视的因素以及值得重新评估的矛盾结论； 2) CO2-EOR 应用模拟地层水中各种 MOC 的腐蚀评估。
