| Abstract Scope |
Magnesium is an abundant and energy-dense metal. A new distillation technology called Gravity-Assisted Multiple Effect Thermal System (G-METS) could enable its use in multiple technologies for recycling and CO<sub>2</sub> drawdown. In addition to magnesium alloy recycling, G-METS can enable low-cost magnesium oxide reduction in a reactive tin cathode Hall-Héroult cell – but up to 33% more productive than for aluminum due to the lower valence of magnesium. It can reduce the energy use of liquid magnesium leaching for rare earth magnet recycling by up to 70%, and cut the cost in half. A molten salt magnesium-air battery can convert magnesium metal to electricity at up to 80% efficiency. And magnesium hydride slurry in a light hydrocarbon is a zero GHG emissions aviation fuel, whose MgO nanoparticle exhaust absorbs CO<sub>2</sub> from the atmosphere as dilute MgCO<sub>3</sub> or Mg(HCO<sub>3</sub>)<sub>2</sub> rain, with calculated aircraft range longer than for plain hydrocarbons. |
