Hydrogen-based direct iron ore reduction with the electric arc furnace (HDRI-EAF) is considered a pivotal low-carbon steel making pathway towards global energy system
analysis of using solar energy to decarbonise steel production in the EU via hydrogen-based direct reduction of iron ore coupled with an electric arc furnace (DRI/EAF). The analysis is based on a comparative levelized cost of product approach, with the BF/BOF benchmark being the
ted in the EU Taxonomy. The main criteria to be complied with is that hot metal produced via BF/BOF must lead to emissions not exceeding 1,331 t CO2e/t of hot metal and EAF steel must not exceed emissions of 0,20 tCO2e/t of steel.5.2. Technology path ays for decarbonisationThe steelmaking sector has a long history of innovation aimed at
For an annual production rate of one million tonnes of liquid steel, there is a steady hydrogen demand of 100–200 MW (depending upon the level of scrap utilisation) and 60–70 MW of additional electricity demand.
(a) Hydrogen storage capacity required to switch current UK steelmaking output (7.2 MtLS/yr) to H-DR/EAF powered by renewable electricity with 50% scrap charge, and corresponding levelised cost of energy (electricity and hydrogen), at various penetrations of wind and solar power.
The renewable hydrogen-based steelmaking system (RHSS) has emerged as an innovative energy system in the pathway of reducing the carbon footprint of ISI. Nonetheless, the sustainable development requirements of RHSS emphasize the critical need for well-planned capacity investments to boost its economic viability.
Over 400 Mt steel is produced from EAF each year, using 2.07 GJ/t (liquid steel) of electricity. However, the production of the electricity may still come from non-green sources. Approximately 7.1% of industrial electricity comes from renewable sources. One difficulty is the ability to use a non-constant supply to support demand whenever required.
Energy demands and resource flows in H-DR/EAF steelmaking for a range of scrap charges. With a 50% scrap charge, hydrogen demand is 25.2 kgH 2 /tLS. To convert the 7.2 MtLS/yr UK steel industry to the H-DR/EAF approach at this level of scrap utilisation would require a hydrogen production rate of 181,720 tH 2 /yr, equivalent to 697 MW.
