    Abstract:

    The use of Hydrogen and natural gas promise a revolution in Syderurgy.
    At the present time, the cost of wind and solar energy are decreasing [1] and also, new sources of natural gas have been discovered [2,3].
    As a consequence, cheap electric energy can be available in a near future, as well as natural gas. This opens new possibilities for the energy use in Steelmaking [4].
    Electric energy can be used for generating hydrogen, for use in reduction processes.
    In this talk, the many possibilities for application of hydrogen and natural gas in Syderurgy are discussed.
    Direct reduction processes based on shaft furnaces can open new possibilities for mini mill facilities.
    A detailed model for the direct reduction of iron oxides in the shaft furnace was developed [5]. This model can be used to simulate the steady state condition of a commercial shaft furnace for pellets and lump ore reductions.
    The model is able to predict the productivity and efficiency of the gas shaft furnace.
