Rio Tinto and Alcoa Corporation announced a revolutionary process to make aluminum that produces only oxygen as a by-product, eliminating all direct greenhouse gas emissions from the traditional smelting process. In Canada alone, use of the technology could eliminate the equivalent of 6.5 million metric tonnes of greenhouse gas emissions, if fully implemented at existing aluminum smelters in the country. That represents an amount roughly equal to taking nearly 1.8 million light-duty vehicles off the road. . . .

Norsk Hydro signs new long-term wind power contract for Norwegian aluminum portfolio
http://www.greencarcongress.com/2018/05/20180517-hydro.html

Norwegian aluminum company Norsk Hydro ASA’s wholly-owned subsidiary Hydro Energi AS has signed a long-term power contract with Blakliden Fäbodberget Wind AB, a Swedish wind power company, for annual baseload supply of 0.66 terawatt hours (TWh) in the period from 2022 to 2041. . . .

The wind park has an installed capacity of 350 MW and is planned to produce around 1.1 TWh annually when finalized. . . .

Primary aluminum smelting energy—the electric power used for electrolysis by the Hall–Héroult processes—was 13,332 kWh per tonne of aluminum, according to World Aluminum. In other words, aluminum production uses a lot of electricity. . . .

1.1TWh/year works out to a capacity factor of 35.9% (for a 365 day year).
