SUMMARY:From digitalization to digital decarbonization: How digital twin technology is optimizing the journey to green steel
DESCRIPTION:Climate change has quickly become the focal point of both challenges and opportunities for today’s iron and steel industry. The industry-wide focuses have shifted from pursuing mainly economic objectives to balancing with environment-centric KPIs such as GHG emissions, energy and raw material efficiency. Many steel producers are facing great challenges on transitioning towards green steel, including: (1) undertaking serious commitments on carbon emission reduction; (2) responding to stakeholder’s pressure on visibility of product carbon footprint; and (3) developing optimal strategy to deal with the impact of carbon pricing. Among many emerging disruptive technologies of Industry 4.0, digital twins have received a high adoption rate due to the steadily growing maturity of IoT, cloud computing and increased number of successful applications. This paper focuses on how digital twin technology can help in driving and optimizing steel producers’ decarbonization strategy. A novel concept of “Carbon Twin” is proposed from the following three perspectives:

Product carbon footprint tracking, to monitor GHG emissions in near real-time and calculate product carbon footprint across entire value chain to create a reliable and transparent GHG emission disclosure to customers and stakeholders. 

Carbon reduction scenario analysis to conduct what-if analysis to assess the impact of different decarbonization technologies, flowsheet variations, process and operation decisions, raw material selection on GHG emissions reduction, to support decarbonization roadmap development and project implementation priorities.

Integrated cost and emissions optimization to introduce carbon taxes and/or green premiums into the integrated steel value chain cost modeling, offering the opportunity to optimize overall profitability by considering process, logistics, and emission constraints, and determine the best strategy to achieve balance between production cost and carbon emissions.

Several industrial project examples will be discussed in the present paper to demonstrate significant benefits of carbon twin.
