You may ask, what is green steel? It is the manufacturing of steel without the use of fossil fuels. And a Swedish start-up company, H2 Green Steel, just order more than 700MW of alkaline electrolyzers for the plant they are building in Boden, Sweden. This plant is currently scheduled to come online in 2025 and will become one of the largest green hydrogen producers in Europe. It will produce 2 and 1/2 tons of steel by the end of 2025, with plans to ramp up this process to produce 5 tons/year by 2030.
Although traditional steelmaking used coal to extract the iron from the iron-oxide ore, both to melt it and to remove its oxygen content, the H2 Green Steel plant will use green hydrogen instead. Renewable-powered electric arc furnaces are then used to turn the iron into steel in an almost entirely carbon-free process.
The 700MW of electrolyzers will make the H2 Green Steel plant one of the largest green hydrogen projects in Europe when it comes online. “The electrolysis plant in Boden will be many times bigger than most existing electrolysis plants today,” says H2 Green Steel’s chief technology officer Maria Persson Gulda.
