Coal is integral to steel production using the BF-BOF route, which accounts for 70% of global steel production
Hydrogen-based approaches need further development and availability of Hydrogen at scale.
Relatively recent vintage and dominance of BF-BOF based steel capacities in major steel producing geographies
Green steel requires uninterrupted availability of green energy – at scale, and at reasonable costs.
Our strategy is dedicated to aiding steel manufacturers in shifting to low-carbon steel production through comprehensive, scalable solutions. We enhance gas conditioning, fuel conversion, CO2 capture, and transforming waste gases from integrated steel plants into low-carbon energy carriers such as clean hydrogen and syngas. This approach allows us to maximize CO2 capture at significantly reduced costs of approximately $30 to $40 per ton, ensuring that our decarbonization solutions are both competitive and economically feasible.
To achieve net-zero CO2 emissions in hydrogen-based steelmaking, we focus on the hydrogen-based direct reduction (DR) route and the injection of hydrogen into blast furnaces. Our approach involves creating integrated solutions that encompass rigorous process modeling, reaction kinetics, and process engineering to maximize hydrogen utilization. Our comprehensive solution ensures the continuous availability and sourcing of hydrogen at optimal economics and scale, utilizing electrolysers, fossil fuels, biomass, natural gas, waste gas, and other feedstocks.
Using a combination of waste gas transformation into clean energy carriers, carbon capture utilization and storage, and hydrogen-based reduction, we enable commercial scale clean steel production.
Dastur Energy prepared the preliminary engineering design and cost estimate for the production of low-carbon-emission steel by capturing almost 3 mtpa of CO2 at one of the largest BF-BOF-based steel plants in the United States.
Feedstock formulation enabled through blending and other preprocessing strategies allows low-cost, low-quality biomass to be blended with higher cost and higher quality to achieve the in-feed specifications at the conversion facility.
