Hydrogen will come from green sources. There is no point using non-green sources, because you will have no market for your more expensive non-green steel. Lots of countries are itching to become the Saudi Arabia of green hydrogen, although personally I suspect the economics is going to have everyone manufacture locally.
- ncmncm 4y agoThere will be green-washers, that buy hydrogen grey and sell it labeled green. That will last until green gets cheaper than grey. Enforcement will be needed. Fortunately you can tell isotopically, and probably by trace amounts of methane and carbon monoxide, green from grey. Unfortunately there is no administrative infrastructure in place for enforcement.
- stubish 4y agoThat will depend on the risk of using green-washed hydrogen in your supply chain, which depends on enforcement (both regulated and social).A bit like keeping child and slave labor out of your supply chain. I suspect it will require requiring certified steel providers for government or certified projects, who are required to use certified hydrogen suppliers. Maybe some countries will do that.
