Hydro starts production at technology pilot

Hydro has started producing the first aluminium metal at the technology pilot in Karmøy. Compared to the world average, the Hydro-developed technology will use 15% less energy in aluminium production and has the lowest CO2 footprint in the world. “Through the technology pilot we have developed the world’s best electrolysis technology: low energy consumption, high productivity and a low environmental footprint,” says Hilde Merete Aasheim, executive vice-president for Hydro’s Primary Metal business area.

The technology pilot consists of physical technology elements and a much improved process control system. Several of these elements can be tailored for and used in Hydro’s existing aluminium plants, which is why the technology is not only good news for Karmøy, but for all of Hydro’s primary aluminium plants.

The technology pilot is designed with an annual production capacity of around 75,000 tonnes, consisting of 48 cells running on the HAL4e technology (12.3 kWh/kg Al) and 12 cells using the HAL4e Ultra technology (11.5 to 11.8 kWh/kg Al). Total costs are estimated at NOK4.3 billion (€450m), consisting of net project costs of NOK2.7bn and around NOK1.6bn in support from Enova.
