Decarbonisation of primary steel production: SIDERWIN

TECNALIA organiza el webinar sobre el proyecto Siderwin que busca descarbonizar la producción primaria de acero.


23 March 2023




3:00 pm - 5:15 pm



The atmospheric concentration of carbon dioxide has increased to unprecedented levels over the past 800,000 years

Steel production accounts for 4% of Europe's (27) CO2 emissions. A breakthrough is needed to reduce it: electrification of steel production is a good candidate to achieve a radical reduction of CO2 emissions.

Revolutionary innovation

SIDERWIN develops a revolutionary innovation for a CO2-free steel production process, with a significant reduction in energy use by electrochemically decomposing iron oxide into metallic iron and gaseous oxygen.

  • This electrolytic process, flexible enough to be powered by renewable energies, will transform iron oxides, including those found in the by-products of other metallurgies, into steel plate with a significant reduction in energy use.
  • This process decomposes under mild conditions, but at intense reaction rates, natural iron oxides, such as haematite, are turned into metallic iron and gaseous oxygen.
