New Casthouse at Karmoy to Support Europe’s Energy Transition with Sustainable Aluminium

Hydro to Launch 110,000 t/yr Aluminium Wire Rod Casthouse in Norway

Norwegian aluminium producer Hydro has unveiled plans to build a 110,000-ton-per-year aluminium wire rod casthouse at its smelter in Karmoy, Norway. This marks the company’s largest domestic investment in a decade, signaling its commitment to supplying the materials needed for Europe’s accelerating energy transition.

Set to begin production in Q1 2028, the new facility will manufacture low-carbon aluminium wire rod specifically designed for power cables. These cables are critical to the growing renewable energy infrastructure across the continent.

Hydro emphasized that aluminium's light weight, durability, and recyclability make it ideal for energy systems. Notably, aluminium conductors provide the same electrical conductivity as copper while weighing only half as much.

Surging Demand for Sustainable Aluminium in Energy Infrastructure

Hydro has observed rising demand for low-carbon aluminium in recent years, even as overall aluminium market activity remains subdued. The shift is driven by Europe’s push for sustainable energy transmission systems, which increasingly favor renewable materials.

“We see in our own sales figures an increasing awareness in the market that future renewable energy must be transported with renewable materials,” said Hydro CEO Eivind Kallevik. This trend aligns with broader decarbonization efforts within the European Union’s Green Deal framework.

Final Investment Decision Expected by Year-End

While the plan is progressing, Hydro stated that a final investment decision will be made in the fourth quarter of 2025. If approved, the Karmoy project will not only expand Hydro’s low-carbon product portfolio but also strengthen Norway’s role in Europe's clean energy material supply chain.

The Metalnomist Commentary 

Hydro’s strategic pivot toward low-carbon wire rod production is more than a manufacturing expansion—it's a signal to the broader metals industry. As governments and utilities demand greener grids, aluminium wire rod is quietly emerging as a frontline material for climate-resilient infrastructure. With weight and recyclability on its side, aluminium could challenge copper in critical grid applications. Hydro’s move reinforces how upstream aluminium strategies are now tightly linked to downstream energy policy.
