On July 2021, the Canadian government has submitted to the UN its Nationally Determined Contribution, committing Canada to reduce its greenhouse gas emissions (GHG) by 40-45% below 2005 levels by 2030, and to be net-zero by 2050. Stelco's integrated steelmaking route is the most efficient method of producing the high-quality steel required to support Canada's economy and the transition to green technologies. However, this process requires the use of carbon as a reductant for iron ore. A portion of the GHG emissions cannot be avoided with currently available technologies. While Stelco considers multiple approaches to reduce its carbon footprint in the long term, carbon capture and storage (CCS) is an important approach to address the shorter-term GHG reduction goals while breakthrough technologies are under development. However, it is currently unclear as to the technical, economic and regulatory feasibility of CCS in Southwestern Ontario. While initial studies have indicated the potential of Haldimand-Norfolk as a location for long term geological sequestration, no in-depth geotechnical review or modelling has been conducted to evaluate the capacity and suitability for long-term carbon sequestration. It is also unclear as to the economic feasibility of CCS, and the optimum integration of CCS technologies into Stelco's complex industrial processes. Finally, there are also uncertainties related to regulatory frameworks for CCS in Ontario and to public perception and necessary stakeholder engagement. To address those uncertainties, Stelco has partnered with a multidisciplinary team of researchers from the University of Waterloo with expertise in CCS and policy decision making. Through advanced modelling techniques, the CO2 storage study will characterize the above mentioned storage site in terms of its capacity and reservoir integrity, and develop an injection/monitoring strategy. The objective of the CO2 capture study is to estimate the economics of CCS when integrated with Stelco's operations. Other objectives are to provide policy recommendations for how Ontario might develop a CCS framework, and to provide recommendations for policy design and strategies for stakeholder engagement around such framework.

2021年7月，加拿大政府已向联合国提交了其全国确定的贡献，并承诺将其温室气体排放量（GHG）降低40-45％，到2030年至2005年的水平低于2005年的水平，到2050年。到2050年。Stelco的综合钢制制造路线是生产高品质钢制所需的高品质钢制的方法。但是，此过程需要将碳用作铁矿石的还原剂。当前可用的技术无法避免一部分温室气体排放。尽管Stelco长期考虑了多种方法来减少其碳足迹，但碳捕获和储存（CCS）是解决较短的减少GHG目标的重要方法，而突破性技术正在开发中。但是，目前尚不清楚安大略省西南部CC的技术，经济和监管可行性。虽然初步研究表明，Haldimand-Norfolk是长期地质隔离的位置的潜力，但没有进行深入的岩土审查或建模来评估长期碳封存的能力和适用性。对于CCS的经济可行性以及CCS技术的最佳整合到Stelco的复杂工业过程中，也不清楚。最后，还有与安大略省CC的监管框架以及公众的看法和必要的利益相关者参与有关的不确定性。为了解决这些不确定性，Stelco与滑铁卢大学的多学科研究人员团队合作，具有CCS和政策决策的专业知识。通过先进的建模技术，CO2存储研究将以上述存储站点的能力和储层完整性来表征上述存储站点，并制定注射/监测策略。二氧化碳捕获研究的目的是估计与Stelco的运营集成时CC的经济学。其他目标是为安大略省如何开发CCS框架提供政策建议，并为围绕此类框架的利益相关者参与的政策设计和策略提供建议。
