That's..... Not how new steel production works.
Coal is a significant component in the production of steel to impregnate it with carbon. It's a fundamental part of how a blast furnace operates. The article literally talks about this...
Even the article about doesn't mention an alternative. An arc furnace relies on scrap it cannot make new steel.
Though, I wonder if we can move more towards charcoals, but even then I wonder if that's just much less effective or if it cannot reach the temperatures or concentrations required for industrial processes.
It has to be. The truck is made from uncoated stainless steel, which can develop small amounts of rust-like corrosion, but absolutely nothing of this fashion.
