Description

ArcelorMittal, an integrated steel producer, has partnered with Primary Energy on several projects at its Northwest Indiana operations to capture and use waste heat and by product fuels. Primary Energy worked with ArcelorMittal to identify an opportunity to more efficiently utilize byproduct fuel from ArcelorMittal’s principle blast furnace (No. 7), and use it to produce up to 90 MW of emission-free electricity. Primary Energy built and owns the project, which uses steam delivered from ArcelorMittal’s existing blast furnace gas recovery boilers.

The North Lake Energy project is capable of supplying more than 20% of ArcelorMittal’s electricity requirements using an onsite waste fuel that had principally been flared. This facility has substantially reduced energy costs compared to purchased power alternatives while increasing reliability of the electric energy supply for ArcelorMittal’s plant operations. The plant produces ~215,000 fewer tons of carbon dioxide when compared to other plants using separate heat and power sources and has been recognized by the United States Environmental Protection Agency for its environmental performance and efficiency.
