Automotive components firm Gestamp and metals producer Hydnum Steel are going to collaborate on starting work to accelerate low-carbon steel production using renewable energy and green hydrogen. The so-called clean steel would be manufactured as automotive components. Gestamp, through its metal recycling subsidiary Gescrap, will supply materials recycled from stamping processes to Hydnum Steel, which will then process it using carbon-free power resources. Hydrogen is an abundant, light and energy-dense gas but is not naturally mined. It is usually created through steam reforming of methane gas, which is carbon intensive, or by electrolyzers separating the hydrogen atom from water. Hydrogen does not contain carbon in its chain and does not emit CO2 at the point of use. To be classified as truly green hydrogen, however, it must be generated from electrolyzers powered by carbon-free resources such as solar, wind, hydro or nuclear.
