MIT spinout Boston Metal has powered up its electricity driven steel production reactor and made over a ton of metal in a crucial step toward commercializing its process. With clean electricity, the process could make steel with zero CO2 emissions.

Does an induction furnace still release CO2 somehow?
Depends on how it’s powered. If the electricity comes from burning coal (coke) or methane, that would emit co2. If it runs off solar/hydro/wind it would only emit co2 from any carbon trapped in the iron ore that manages to burn instead of becoming incorporated into the steel.
The CO2 comes from adding the coke to make steel, not getting the thing hot
