Case Study: ArcelorMittal achieves clearer waste heat recovery decisions with Capgemini Engineering

Arcelormittal Uses Data And Analytics To Pursue Energy Efficiency

ArcelorMittal, the global steel manufacturer, needed a better way to drastically reduce waste heat across its industrial processes as part of its net-zero strategy. Traditional measurement and recovery methods were not suited to its sites, so the company partnered with Capgemini Engineering on the ANAGREEN project to create new models and analytics for identifying waste heat and evaluating recovery options.

Capgemini Engineering implemented physical and techno-economic models, data analysis processes, and optimization methods to assess potential solutions such as heat exchangers, heat pumps, and thermal storage. The result was a decision-support system that clarified costs, savings, payback time, and CO2 reduction potential, with models estimating an annual recovery potential of 2.4 TJ (0.67 TWh) for steel plants in France.
