Metallurgy Guru - Sustainability Materials Science - Making Green Steel with Hydrogen, 13022022

In terms of 'direct sustainability', the steel-making process can be significantly improved to reduce energy consumption and CO2 emissions by using ''green power' and Hydrogen. This lecture considers the use of hydrogen (in lieu of coal or natural gas) when manufacturing steel in blast or electric arc furnaces and the corresponding redox reaction that provides water as a reactant instead of CO2. Key mechanisms of hydrogen-based direct reduction & hydrogen-based plasma reduction are explained
