Iron and steel manufacturing is among the most energy-intensive industries and accounts for the largest share, approximately 27 percent, of global carbon dioxide (CO2) emissions from the manufacturing sector.

 Although studies from around the world have identified a wide range of energy-efficiency technologies applicable to the steel industry that have already been commercialized, information is limited and/or scattered regarding emerging or advanced energy-efficiency and low-carbon technologies that are not yet commercialized. This report consolidates available information on 56 emerging iron and steel industry technologies, with the intent of providing a well-structured database of information on these technologies for engineers, researchers, investors, steel companies, policy makers, and other interested parties.

For each technology included, there are  evaluations  on energy savings and environmental and other benefits, costs, and commercialization status and also references for more information.

Kobe Steel, along with MIDREX Technologies, is the world leader in direct reduction (DR) technologies.
Kobe Steel has developed a coal based DR process which utilizes non-coking coal as a reductant instead of natural gas and is expanding the market share in thecoal-based iron-making field. FASTMET, FASTMELT and ITmk3 are low cost processes that produce directlyreduced iron (DRI) without coke, hot-metal without fired- pellets and iron-nuggets without lump-ore, respectively. These processes are currently being, or are about to be used commercially
