Michaeljob do you think the hydrogen would need to be high purityto be used as a reductant? My gut feeling would be that it would not need to be high purity, and the only downside of using low purity would be the associated CO2 emission generated during the process.

I wonder whether the rotary tube reactor they tested that produced low purity hydrogen would be a consideration, to produce low cost, low purity hydrogen?
If biomethane was used as the feedstock, then having a small carbon omission during the steelmaking process would still be carbon negative?
