Nucor Introduces Elcyon(TM), First Sustainable Steel Product Engineered Specifically For Offshore Wind Energy Applications

The title of this post, is the same as that of this press release from Nucor Corporation.

This is the first paragraph.

Nucor today introduced Elcyon™, the Company’s new sustainable heavy gauge steel plate product made specifically to meet the growing demands of America’s offshore wind energy producers building the green economy and its necessary infrastructure. Nucor will manufacture Elcyon at the company’s new, $1.7 billion state-of-the-art Nucor Brandenburg steel mill in Kentucky , which produced its first steel plate at the end of December 2022.

It sounds impressive, but it should be if $1.7 billion has been spent.

This paragraph, says more about the process.

Elcyon is a clean, advanced steel product made using Nucor’s recycled scrap-based electric arc furnace manufacturing process. Nucor’s circular steelmaking route has a greenhouse gas emissions intensity that is one fifth the global blast furnace extractive steelmaking average, based on Scope 1 and 2 emissions. Utilizing Thermo-Mechanical Controlled Processing (TMCP) at the new mill, Elcyon, the only steel of its kind in the United States was created specifically to meet the rigorous quality standards of offshore wind energy designers, manufacturers and fabricators. Along with meeting Euronorm specs, Elcyon is characterized by larger plate dimensions, improved weldability and excellent fracture toughness, as compared to competing products.

What more can a steelmaker want?

  • It uses steel scrap to make new steel.
  • The process could be powered by green electricity.
  • The process cuts emissions to twenty per cent.
  • The steel is what customers want.
  • The steel has better properties  than competing products.

These two paragraphs talk about the prospects for Elcyon.

Nucor Steel Brandenburg is the first steel plant in the world to pursue certification under LEED v4 from the U.S. Green Building Council, the highest standard for sustainable building design, construction, and operation. The new mill is located in the middle of the largest steel plate-consuming region in the country and will be able to produce 97% of plate products consumed domestically, with a potential output of 1.2 million tons of steel annually.

Elcyon and the Brandenburg mill both draw upon Nucor’s 50 years of industry leadership in sustainable steel production. From last year’s launch of Econiq™, the world’s first net-zero steel available at scale, to recently becoming the first major industrial company to join the United Nations 24/7 Carbon-Free Energy Global Compact, Nucor has consistently worked to meet the needs of its customers and other stakeholders while protecting the well-being of our planet.

Nucor have certainly done their market research and appear to be very scientifically green.

In the About Nucor section of the press release, this is the last sentence.

Nucor is North America’s largest recycler.

This is some statement to make, if it weren’t true! Wikipedia says this about the company.

Nucor operates 23 scrap-based steel production mills. In 2019, the company produced and sold approximately 18.6 million tons of steel and recycled 17.8 million tons of scrap.

The home page of the Nucor web site also makes this claim.

North America’s Most Sustainable Steel And Steel Products Company

Perhaps, the UK government needs to ask Nucor to build one or more of their scrap-based steel production mills in the country to produce all the steel plate we will need for our growing offshore wind industry.

We certainly have the GW to power the arc furnaces.


Nucor is a big beast to watch!

  1. You are missing a huge part of the story. Electric arc furnaces use an enormous amount of electricity. UK electricity prices are at least 3x US prices and in some cases more like 5x. Nucor can ship steel to the UK for less than the cost of making it in the UK.
