Norsk Hydro has decided to invest around NOK 60 million to upgrade the electrolysis cells at the aluminum plant in Ardal in Norway. The project will improve the working environment, reduce energy consumption and contribute to increased profitability. Work on the upgrade will start in the spring of 2022 and will improve the working environment for the operators at the metal plant, while reducing energy consumption and CO2 emissions from the process. This contributes positively to the profitability of the plant. In addition, the investment will also facilitate Hydro Årdal's use of next-generation cell control system, which has been further developed from the technology used in Hydro's technology pilot at Karmøy. Introduction of the new cell control system is expected to start at the end of 2022. The energy savings from the project will be approximately 860 MWh annually.
