    Primary Aluminum: Inert Anode and Wettable Cathode Technology in Aluminum Electrolysis

    Editor’s Note: Unlike aluminum’s sustainable advantage in recycling, primary aluminum production (which uses carbon anodes in the Hall-Héroult process), continues to be energy intensive and a greenhouse gas (GHG) producer. Ignoring the effect of CO2 generation in the coal/hydrocarbon power equation, the use of carbonaceous anodes in the smelting process generates GHGs as carbon is […]
