Hydrogen is not at all required for steel melting. Look at Boston Metal. In fact I would argue its the worst solution of the two by a big margin.

For ammonia this will eventually be required.

Smelting isn't just melting, it chemically reduces Iron oxide and needs a reducing agent (hydrogen, CO etc.)

Aluminum is reduced through electrolysis. I think he means that method can be used for iron which means you don't have to use electrolysis on hydrogen.
