Abstract Scope |
Large-scale electrification is seen as a pathway to carbon neutrality; in one estimate, the goal to “electrify everything” would imply tripling the electricity consumption of the United States (currently approximately 4,000 TWh per year). In the case of ironmaking – whether by using green hydrogen or oxide electrolysis – the electricity requirement would be approximately 4 MWh per tonne of iron. Recycling scrap steel requires approximately one order of magnitude less electricity, around 400 kWh per tonne of steel. In this presentation, the fundamental basis of these figures will be presented, to support future choices for steel producers. |
