Hydro has decided to invest around NOK 47 million in the casthouse at its Årdal aluminum plant in Norway. The investment will improve safety, lower energy consumption and CO2 footprint and contribute to increased production. The investment will go to a new preheating chamber, which will be installed during the year. This will be used for preheating cold metal and post-consumer aluminum before it is added to the casting process. Today, the casting furnaces are used for preheating, but a dedicated preheating chamber will make the casting process more efficient, safer and it will use surplus heat from the casting furnace as an energy source.The casting furnace emits excess heat during operation. This can be used as an energy source for the new preheating chamber. This results in a reduction in the CO2 footprint and the increased efficiency achieved with the preheating chamber will enable Hydro Årdal to increase production by about 5,000 tonnes a year.This investment comes on top of a recently announced NOK 60 million investment to upgrade the electrolysis cells at Hydro Årdal.
