Laboratory experiments on hydrogen plasma smelting reduction show potential for emissions reduction in the iron and steel industry, indicating a path towards carbon neutrality.
The iron and steel industry faces the challenge of fulfilling climate change commitments such as the Paris Agreement and the European Green Deal. These aim for carbon neutrality by 2050 and significant emissions reduction by 2030. Carbon Direct Avoidance (CDA), focusing on Hydrogen Plasma Smelting Reduction (HPSR), emerges as a promising emission-reduction pathway. HPSR, utilizing electrical energy and hydrogen, is under development at Montanuniversitaet Leoben and K1-MET GmbH. The study explores laboratory experiments on the impact of cathode geometry, plasma gas, and iron ore feed rate on HPSR. It assesses varying pre-reduction states’ effects on hydrogen utilization and process time while maintaining consistent product quality. The research seeks optimal combinations to maximize hydrogen use, contributing to industry emission reduction efforts and sustainability goals.
