Hydrovolt AS stands as one of Europe’s leading battery recycling companies, transforming end-of-life electric vehicle (EV) and industrial batteries into valuable raw materials. Established in 2020, the company operates a state-of-the-art recycling facility in Fredrikstad, Norway, with the capacity to process batteries from approximately 25,000 EVs annually, equivalent to 12,000 tons of battery packs.

The company’s dedication to environmental sustainability is evident through its innovative recycling processes, which produce black mass with a 75% lower carbon footprint compared to traditional mining methods. Hydrovolt’s approach emphasizes material recovery and circular economy principles, aiming for complete material recuperation while maintaining strict safety and quality standards.

Battery Technology

Hydrovolt’s advanced recycling technology sets new standards in battery material recovery. The company’s process efficiently extracts and isolates up to 95% of battery components, including valuable materials such as plastics, copper, aluminum, and black mass – a compound containing essential elements like nickel, manganese, cobalt, and lithium.

The facility incorporates automated systems for battery discharge and dismantling, ensuring safe and efficient processing. This automation extends to managing electrical energy discharge from batteries, with residual energy being utilized within operations or distributed to the local power grid. The recovered materials maintain high quality standards, making them suitable for immediate reuse in new battery production.

Hydrovolt’s technical processes focus on minimizing environmental impact while maximizing material recovery. The company’s methods ensure that recovered black mass can be directly supplied for new battery production, while aluminum components are processed into commercial-grade products. This efficient system supports the creation of a sustainable battery value chain, reducing dependence on primary raw materials.

Recent Projects

In early 2025, Hydrovolt initiated expansion plans into France, establishing a new facility in Hordain to strengthen its European presence. The company also formed a strategic partnership with NG Metall and launched a research collaboration with SINTEF and IFE to advance battery recycling technologies.

Additionally, Hydrovolt introduced the world’s most automated battery recycling line, demonstrating its commitment to technological advancement and operational efficiency.

Investors

As of January 2025, Norsk Hydro ASA acquired complete ownership of Hydrovolt, purchasing the remaining shares from Northvolt for NOK 78 million. This transition from a joint venture to full ownership under Hydro marks a significant milestone in Hydrovolt’s development. The company maintains its commercial collaboration with Northvolt’s Revolt plant while actively seeking new partnerships to secure long-term financing and growth opportunities.
