| Abstract Scope |
Molten salt electrolysis with a liquid tin or lead reactive cathode overcomes multiple challenges in reduction of magnesium oxide to metal, particularly the low density and high activity of magnesium metal. It can use carbon anodes in a design very similar to the Hall-Héroult cell, or solid oxide membrane (SOM) anodes for pure oxygen by-product production. G-METS distillation is potentially much more energy-efficient and lower cost than traditional batch distillation for separation of the magnesium metal product from the reactive cathode material. This talk will present new developments in this process. Electrolysis experiments with carbon and SOM anodes show outstanding current efficiency for both. An updated techno-economic analysis estimates capital and operating costs using both carbon and SOM anodes. Life cycle analysis of the process under three scenarios estimates the cradle-to-gate environmental impact. And a new thin-SOM anode design can improve scalability and energy efficiency. |
