Under a $2,909,514 Cooperative Agreement awarded by the U.S. Department of Energy's Advanced Research Projects Agency-Energy (ARPA-E) program (CFDA 81.135), Tufts University will develop a new approach to directly reducing iron ore concentrates using ammonia to eliminate CO2 emissions and decrease costs in the ore-to-steel value chain. Tufts' method aims to eliminate all direct process emissions from ironmaking and reduce emissions from iron ore pellet induration by over 60%. The project is expected to save 10-25% of the total cost of hot-rolled coil steel, or more if using lower-grade ores. The university has also awarded a $247,085 sub-grant to the University of Minnesota's Natural Resources Research Institute (NRRI) to produce iron oxide concentrates, characterize raw materials and metallic iron products, and evaluate the energy required to melt the metallic iron. Through this collaboration, the project seeks to revolutionize the U.S. ore-to-iron process and significantly improve the environmental and economic performance of steel production.
