How does iron become steel
WebJun 2, 2024 · In green steel production, hydrogen made from renewable energy replaces fossil fuels. Australia exports almost 900 million tonnes of iron ore each year, but only makes 5.5 million tonnes of steel ... As of 2024 , steelmaking is estimated to be responsible for around 11% of the global emissions of carbon dioxide and around 7% of the global greenhouse gas emissions. Making 1 ton of steel produces about 1.8 tons of carbon dioxide. The bulk of these emissions results from the industrial process in which coal is used as the source of carbon that removes oxygen from iron ore in the following chemical reaction, which occurs in a blast furnace:
