Sweden’s Grand Plan To Make Zero-Carbon Steel

The title of this post is the same as that of this article on theTelegraph.

It adds a lot of colour and background to Sweden’s plan to make zero-carbon stell using a process called HYBRIT, that I wrote about in Funding Award to Supply An 8MW Electrolyser and is illustrated in this infographic.

The amount of hydrogen needed is large as this paragraph from the Telegraph article says.

HYBRIT’s demonstration plant, for which an investment decision is due in 2022, will require 400MW of power just for the electrolysers to make the hydrogen. Sweden’s largest existing wind farm, Björkhöjden, produces just 288MW. Then to store the hydrogen, Vattenfall plans to build 120,000 m3 of lined underground storage, enough to store 100GWh worth of the gas.

Will they procure the electrolysers from the UK’s experts in the field; iTM Power? This innovative company is building the world’s largest electrolyser factory in Rotherham, which will be able to produce a GW of electrolysers in a year.

Conclusion

This well-written article in the Telegraph explains a lot about steel produced using hydrogen instead of coal.

Sweden has a lot of advantages at Lulea to create steel.

  • The iron ore is mined locally.
  • Sweden has ninety percent of Europe’s iron ore.
  • Ships can sail to Lulea, which is at the top of the Baltic.
  • There is gigawatts of zero-carbon electricity from the River Lule.
  • They can build wind farms in the area, which has a low population.

It does look that they might export the iron ore as sponge iron, which can then be processed directly into steel products using electric arc furnaces.

  1. I thought steel was carbon mixed with iron plus other ingredients so, is zero carbon steel real?
