OSE Case
- Recycling of steel from scrap at 1kWhr/kg
energy input. See Solar Steel.
- Another route is reduction of ore using hydrogen. See Hydrogen Reduction Smelting
- OSE's case would be to produce steel from direct reduction, which is more efficient and lower temperature than a blast furnace. https://en.wikipedia.org/wiki/Direct_reduced_iron
- Iron mining in the USA - [1]
- Chromium mining (for stainless steel) - Chromite (FeCrO) is reduced to Ferrochrome (FeCr) via carbothermic reduction. Chromite in Oregon, Montana, California - [2]
Distributed Market Substitution Calculations
- Global production is 140 million tons
