The existing casting center at Rio Tinto’s Alma plant will be expanded to […]
By Rose Eaton, Light Metal Age. In a village in Norway called Sunndalsøra, nestled between a crystal blue fjord and two massive mountain ranges, lies Hydro Sunndal, the largest primary aluminum plant in Europe and one of the most modern. Overabundant water flowing down the mountains and the deep-sea fjord have provided the area with […]
By Halvor Kvande, NTNU (Retired); Gudrun Saevarsdottir, Reykjavik University; and Barry Welch, Welbank Consulting. Abstract While global average greenhouse gas (GHG) emissions have changed little over the last several years, the best available data has become more reliable and has showed lower emissions. The electrolysis process has now been performed with a low emission rate […]
Hydro is entering a new development stage for its HalZero production technology, which aims to decarbonize the aluminum smelting process. With support from the Norwegian government, the company plans to invest in a test facility for the new technology. This puts Hydro on track to deliver pilot production of zero-carbon primary aluminum by 2030. […]
