The goal of the ROSIE program is to develop pathways to zero emissions ironmaking and ultra-low life cycle emissions for steelmaking. The program seeks to fund the development and demonstration of novel technologies that produce iron-based products from iron-containing ores and alternative feedstocks without process emissions in the ironmaking step. The Program’s technologies will demonstrate a path to cost-competitiveness with traditional incumbent carbothermic blast furnace ironmaking. The technologies funded through this program have transformative potential, because no technology route exists today that meets both this emissions constraint and this cost parity goal.

The program will have two categories:

1. Category A includes processes from ore to ironmaking.
2. Category B must include ironmaking but can extend to downstream steel production.

If successful, novel ironmaking technologies meeting the metrics set forth by the program will enable a reduction of U.S. emissions by over 65 million tonnes (Mt) carbon dioxide emitted (CO2e) annually (~1% of U.S. emissions) and global emissions by over 2.9 gigatonnes (Gt) annually (5.5 % of global emissions).
