<p>A mixture of carbon monoxide and hydrogen is derived from carbon dioxide and water, with an energy source (preferably renewable energy) required to drive these reactions. This mixture of carbon monoxide and hydrogen is injected into a furnace. Heat is added, either to the iron ore in the furnace or to the gas — either before entering the furnace or while in the furnace. Both of these gases reduce the iron oxide to metallic iron. The waste products are carbon dioxide and water, which can be recovered to form further carbon monoxide and hydrogen.</p> |
