High-Temperature Electrolysis Integrated With Direct Reduced Iron Process for Producing Low-Carbon Steel

High-temperature electrolysis (HTE) of steam is one of the most energy-efficient techniques for producing hydrogen. Coupling the process with a direct reduced iron (DRI) plant can help the steel industry lower its carbon footprint by using the low-carbon hydrogen as a reducing agent and fuel, instead of synthesis gas derived from either natural gas or coal. The present study aims at predicting the future performance of an integrated DRI plant via process modeling and simulation. As a result of this integration of HTE, the CO2 intensity of steel production is significantly reduced.
