Project Description

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.

Environmental Benefits

  • Produces up to 90 MW of emission-free electricity
  • Produces 215,000 fewer tons of carbon dioxide when compared to other plants using separate heat and power sources.
  • The United States Environmental Protection Agency recognized North Lake Energy’s 2007 operations for environmental performance and efficiency

 

The project captures and recycles heat from ArcelorMittal’s principle blast furnace, producing up to 90 MW of electricity, providing more than 20% of ArcelorMittal’s electricity requirements, increasing reliability of the plant electric supply, substantially reducing energy costs compared to purchased power alternatives, and producing 215,000 fewer tons of carbon dioxide when compared to other plants using separate heat and power sources.

STEEL MILL WASTE HEAT TO ELECTRICITY

The Heat is Power Association (HiP) is the trade association for the waste heat to power (WHP) industry. WHP uses waste heat from industrial processes to generate electricity with no additional fuel, no combustion, and no incremental emissions. HiP educates policy makers about clean energy from waste heat and advocates for policies that provide parity for WHP with other sources of clean energy.
