Norway, Oct. 20 -- Hydro has produced aluminium using its new HalZero electrolysis technology for the first time. The milestone marks an important step in Hydro's work to develop a new primary aluminium production process with the aim of achieving net-zero emissions.Since 2016, Hydro's technology teams have been working to develop HalZero, an entirely new process for producing primary aluminium, which could replace the technology used globally today, first patented in 1886. The new technology is based on converting alumina into aluminium chloride before electrolysis in a process designed to keep chlorine and carbon in closed loops. The long-term ambition is to eliminate CO2 emissions from both electrolysis and anode production, releasing ox...
