"We are already producing aluminum with the new technology and we are very excited now to be able to start using this technology on an industrial scale," said Hilde Merete Aasheim, Hydro's executive vice president in charge of the Primary Metal business area.

Compared to the world average, the technology developed by Hydro consumes 15% less energy in aluminum production and has the lowest carbon footprint in the world. Low energy consumption, combined with high productivity, means that Hydro can calmly say that the technology pilot project at Karmoy will be a world leader.

“With the technology pilot project, we developed the best electrolysis technology in the world - with low energy consumption, high productivity, and low environmental footprint,” said Aasheim.

The pioneering technology pilot project consists of elements of physical technology and a much better control system. Many of these elements can be adjusted and used in other Hydro aluminum plants, which means that the technology is not only good news for Karmoy, but for all Hydro's primary aluminum plants.

The project was designed for an annual production capacity of approximately 75 thousand tons, consisting of 48 cells with HAL4e technology (12.3 kWh / kg) and 12 cells with HAL4e Ultra technology (11.5 - 11, 8 kWh / kg).

Total costs are estimated at NOK 4.3 billion, of which NOK 2.7 are net project costs and NOK 1.6 billion is financial support received from Enova. & nbsp;
