BECCS Beats Hydrogen For Decarbonizing Steel In Europe: ArcelorMittal

The title of this post, is the same as that of this article on S & P Global Platts.

This is the first paragraph.

Bioenergy with carbon capture and storage (BECCS) offers a more cost-effective, readily available solution for decarbonizing the steel industry in Europe than clean hydrogen, steel producer ArcelorMittal’s head of strategy David Clarke said May 17.

So what do they mean by bioenergy?

To make iron from iron ore, you need a reducing agent like carbon or hydrogen.

Iron ore is rich in oxides of iron.

The carbon is usually some form of coal, which produces large amounts of carbon dioxide with the oxygen from the iron oxides.

Hydrogen produces lots of water with the oxygen.

David Clarke of ArcelorMittal explains the process in the article.

“We know biomass worked as a replacement for coal,” he said. “We’ve been using it in our operations in Brazil and other places for many, many years. We have a project in Belgium that we’ll be starting up next year using waste wood, using that to make bio-coal,” with a project to take the emissions from the bio-coal to produce bioethanol.

Is this a case of Back-To-The-Future? If I remember my history, didn’t Iron Age men use charcoal to smelt iron and other metal ores?

If those scientists from Velocys can make Sustainable Aviation Fuel and biodiesel from household waste and used disposable nappies, can they apply their magic to make bio-coal?

I see great cost advantages with this process, as surely it would enable existing blast furnaces to be used, provided they were fitted with carbon capture and storage.

  1. There is some interesting Wealden history here – https://en.wikipedia.org/wiki/Wealden_iron_industry

  2. I am afraid to tell you that although IIRC one can reduce copper and silver with hydrogen, you can’t reduce iron with it.

  3. I understand the Swedes have already done it!
