If you believe Elon Musk then using hydrogen is horribly inefficient. If you want truly green steel then why not look at biomass gasification coupled to a Midrex direct reduced iron module?
Last time the biomass was used for metallurgy the Great Britain lost its forest almost completely. And you can not even compare iron amounts produced then and nowadays.
@@yurikorobeinikov2195 Not true. Brazil runs blast furnace pig iron production from charcoal produced from trees grown on plantations. Nucor had a joint venture on this for a while. I think the only way Hydrogen production will work is if generated from the heat of a nuclear reactor not from electrolysis.
@@felixyusupov72991) Brazil is not a leading steelmaker by volume. Far less than USA, or EU. Not to compare with China. 2) are you really sure that Brazil is a good example of sustainable forestry?
I think if you want "green" steel then nuclear powered hydrogen is the only option. Biomass is green but wouldn't work for most of the world. I agree with that.
I thought Musk’s stance on hydrogen is specifically that it makes an unwieldy fuel for consumer vehicles (difficult to store in pure form, energy intensive to store in and release from hydrides, etc.).
