Technology Description:

Big Blue Technologies (BBT) proposes the world’s most efficient method to produce magnesium (Mg), a light metal with a high energy and carbon footprint whose demand is increasing due to its application in vehicle and aircraft light-weighting and portable electronics. BBT will demonstrate a continuous production system with best-in-class material and energy efficiency by extracting crude Mg from ore in a 50-kW electric arc furnace and purifying it using a dual high-temperature condenser. If successful and scaled, BBT will produce Mg at the globally competitive cost of <$2/kg, reduce total process energy consumption (<15 kWh/kg), and establish a path for net-zero process emissions, providing a cleaner, cheaper, domestic source of this critical metal.
