The article doesn't describe the difference in process between electric arc and blast furnaces properly. Coking/metallurgical coal isn't just used for heat in steel production but because it creates a chemical reaction which normal (thermal) coal doesn't. With an electric arc furnace, you have to use methane to achieve direct reduction instead. It's possible to use hydrogen instead of methane to do this although that doesn't make sense from an emissions standpoint unless you have a source of H2 which is produced by electrolysis using a non CO2 emitting source of electricity (and moreover from a global perspective you would ideally also want to be sure that there isn't a better use of that electricity). I'm not clear on if that's what's proposed here but I would assume not - as I would expect the UK government would be shouting about this very loudly if so given the level of hype there is around hydrogen.
