CO2 Emissions, New Processes, Efficiency


The Largest Transition Since Decades

According to data provided by the World Steel Association, on average, 1.89 tonnes of CO2 are emitted during the production of one tonne of steel. The steel industry accounts for approximately 8% of anthropogenic CO2 emissions. A significant reduction in fossil energy usage and CO2 emissions is required.

Most countries are introducing instruments to move forward with the reduction of CO2 emissions, such as emissions trading systems or carbon taxes. Steel consumers, for example, the automotive industry also push forward to reduce the CO2 footprint of their supply chain.

This ongoing transition leads to fundamental changes of the whole industry in both, its processes and its overall operations.

Most of the direct emissions (Scope 1) in integrated steel manufacturing originate from coking, the sinter process and the blast furnace process. Additional direct and indirect emissions (Scope 1 and Scope 2) can be associated to downstream processes like reheating and rolling.

All major steelmakers are working on long-term decarbonization projects, implementing a broad set of process technologies. Regarding the blast furnace, pulverized coal injection (PCI) is replaced by natural gas and, if available, hydrogen produced using renewable energy. New direct reduction plants and electric arc furnace plants are under construction, which will eventually replace blast furnaces in order to cut emissions.

Conventional Blast Furnace Route And New DRI / EAF Route

Artificial Intelligence and Machine Learning - assisted production has the potential to lower energy consumption, increase yield and lower the carbon footprint already now, for existing plants, and for newly constructed steel mills.

Smart Steel Technologies' AI-based process control software supports the transition of the steel industry.

In 24/7 production use, the software helps to minimize all inefficiencies across all production routes. Each reduction of quality deviations, energy inefficiencies and CO2 inefficiencies minimizes the CO2 footprint of steel products.
