The ULCORED coal based concept is simulated based on the production of syngas using existing coal gasification technology. The shifter gives the option to produce CO2-lean H2 from coal/biomass for in plant use. Large CO2 emissions arise on site from the use of natural gas in heating ovens and from the use of electricity in EAF melting. In the case of these coal based systems, production of "excess gas" to be used as fuel gas in various processes will reduce the CO2 emission for the total site.
