Use of 100% hydrogen in a shaft furnace (SF) to reduce iron ore has the potential to reduce emissions from iron and steel production significantly. In this work, results from the techno-economic assessment of a H<sub>2<\/sub>-SF connected to an electric arc furnace(EAF) for steel production are presented under two scenarios. In the first scenario H<sub>2<\/sub> is produced from molten metal methane pyrolysis in an electrically heated liquid metal bubble column reactor. Grid connected low-temperature alkaline electrolyser was considered for H<sub>2<\/sub> production in the second scenario. In both cases, 59.25 kgH<sub>2<\/sub> was required for the production of one ton of liquid steel (tls). The specific energy consumption (SEC) for the methane pyrolysis based system was found to be 5.16 MWh\/tls. The system used 1.51 MWh\/tls of electricity, and required 263 kg\/tls of methane, corresponding to an energy consumption of 3.65 MWh\/tls. The <a href=\"https:\/\/www.sciencedirect.com\/topics\/engineering\/water-electrolysis\" title=\"Learn more about water electrolysis from ScienceDirect's AI-generated Topic Pages\" class=\"\">water electrolysis<\/a> based system consumed 3.96 MWh\/tls of electricity, at an electrolyser efficiency of 50 KWh\/kgH <sub>2<\/sub>. Both systems have direct emissions of 129.4 kgCO2\/tls. The indirect emissions are dependent on the source of natural gas, pellet making process and the grid-emission factor. Indirect emissions for the electrolysis based system could be negligible, if the electricity is generated from renewable energy sources. The levellized cost of production(LCOP) was found to be $631, and $669 respectively at a discount rate of 8%, for a plant-life of 20 years. The LCOP of a natural gas reforming based direct reduction steelmaking plant of operating under similar conditions was found to be $414. Uncertainty analysis was conducted for the NPV and IRR values.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Circa 2021 Decarbonisation of the iron and steel industry would require the use of innovative low-carbon production technologies.
