Abstract
Ironmaking is the most energy intensive and generates the majority of CO2 emissions associated with steelmaking. The most advanced and promising technology to reduce and eliminate CO2 emissions associated with Ironmaking is Direct Reduction with Natural Gas and Hydrogen. As the industry leader, Midrex Technologies Inc. been actively researching and developing technology solutions to adapt the MIDREX® process for both a stepped transition from Natural Gas to Hydrogen (MIDREX FlexTM) and for the ultimate carbon-neutral direct reduction process (MIDREX H2TM).
