Direct Reduced Iron Models

Direct Reduced Iron Models#

H2I contains two direct reduced iron (DRI) models, one is for a facility run using natural gas and another facility run using hydrogen.

The original models were constructed in Aspen Pro and translated into Python and added to H2I. The models were developed in conjunction with Lawrence Berkeley National Laboratory (LBNL).

The models implemented in H2I are:

Natural Gas Electric Arc Furnace
- NaturalGasIronReductionPlantPerformanceComponent
- NaturalGasIronReductionPlantCostComponent
Hydrogen Electric Arc Furnace
- HydrogenIronReductionPlantPerformanceComponent
- HydrogenIronReductionPlantCostComponent

Note

The DRI model outputs sponge iron, which is low in carbon content. The LBNL model calls the outputs pig iron, but that's typically produced using a blast furnace rather than through the DRI process and has higher carbon impurities.
