ArcelorMittal tests “green” hydrogen in iron ore reduction process


Leading steel company ArcelorMittal successfully tested the use of “green” hydrogen in the production of direct reduced iron (DRI) at its steel mill in Contrecoeur, Quebec. The company says this test is an important step in the company’s journey to produce zero-carbon steel through the DRI-based steelmaking pathway using green hydrogen as an input. .

The purpose of the test was to assess the ability to replace the use of natural gas with hydrogen in the iron ore reduction process. In this first test, 6.8% of the natural gas was replaced with hydrogen over a 24-hour period, which contributed to a measurable reduction in carbon dioxide emissions.

The hydrogen used in the test was produced by a third-party electrolyser (a device that produces hydrogen from electricity and water) and was then transported to Contrecoeur. This is a major step forward since the iron ore reduction process alone contributes to more than 75% of ArcelorMittal Long Products Canada’s (AMLPC) global carbon dioxide emissions.

AMLPC is now evaluating the possibility of carrying out further tests over the next few months by increasing the use of hydrogen at the DRI plant which, according to the company, could potentially reduce arbon dioxide emissions at Contrecoeur by several hundreds of thousands of tons per year.

The potential use of electrolyzers to produce hydrogen at Contrecoeur will depend on certain criteria, in particular the availability of sufficient electricity to power the units, he adds.

“We have just demonstrated that Quebec can become a world pioneer in the production of low CO emissions.2 steel, by reducing its greenhouse gas emissions,” commented AMLPC’s Chairman and CEO, François Perras, on the occasion of this important step.

ArcelorMittal aims to reduce its carbon dioxide emissions intensity by 25% by 2030 globally and achieve carbon neutrality by 2050.
