Abstract Scope |
The world is now pushing for a low-carbon future. Presently, 70% of aluminum is produced with power from fossil-fuelled power plants, and while the introduction of solar and wind generation is accelerating, this has technical constraints and limitations. Gradually de-carbonizing energy production is the most effective way for the primary aluminum industry to reduce emissions. Globally the best result will be achieved by maximizing aluminum production in regions that can provide clean green power, while simultaneously operating at minimum unit energy consumption rate for the technologies using fossil fuel based power. Closing down hydro powered smelters to reduce national emissions risks carbon leakage, because growing metal demand is primarily met with increased production capacity in countries using non-renewable high emission level power sources. This paper opens debate on the possibilities for reducing CO2 emissions in light of our global responsibility. |
