Europe’s push for energy independence through green technology has suffered a major setback following the bankruptcy of Swedish battery maker Northvolt, once hailed as a homegrown champion of the electric vehicle revolution.

Founded by former Tesla executives Peter Carlsson and Paolo Cerruti, Northvolt raised more than $13 billion in just over seven years, attracting backing from major investors including Volkswagen and Goldman Sachs. The company built two factories in Skellefteå and Västerås between 2019 and 2024, aiming to capture 25 percent of the European battery market with 150 gigawatt hours of annual capacity.

That ambition unraveled when Northvolt filed for bankruptcy in March 2025, prompting the departure of Carlsson and casting doubt over Europe’s ability to build large-scale green manufacturing from scratch. In August 2025, US-based lithium-sulfur battery firm Lyten acquired Northvolt’s remaining assets in Sweden, Poland and Germany, including its production site in Skellefteå and research hub in Västerås.

Tom Johnstone, interim chairman of Northvolt’s board, said building a domestic battery industry remains critical for Europe but described it as a long-term effort requiring patience and sustained commitment. A company statement cited geopolitical instability and shifting market demand as contributing factors behind the collapse.

Despite the setback, global investment in green technology continues to grow. Bloomberg data shows spending on the energy transition reached $2.3 trillion in 2025, led by China, India and Japan. Analysts argue Northvolt’s failure reflects execution challenges rather than a broader retreat from clean energy.

Jan Larsson, head of Business Sweden, said the bankruptcy was a blow to the local community but insisted Sweden retains a strong battery ecosystem, particularly through collaboration with Finland and Norway.

Other companies say they have learned lessons from Northvolt’s rapid expansion. Swedish sodium-ion battery startup Altris has shifted toward incremental growth and partnerships. In January 2026, it teamed up with Czech chemical group Draslovka to manufacture key battery materials rather than attempting full vertical integration.

Beyond batteries, wave energy developer CorPower Ocean is pursuing a phased approach. Founded in 2012, the company is developing a 10-megawatt project off northern Portugal with support from a €40 million EU Innovation Fund grant.

Industry leaders say regulatory complexity remains a hurdle. Licensing rules vary widely across European countries, slowing project development. Even so, advocates argue the energy transition remains central to Europe’s economic security and sovereignty.

Whether Lyten focuses on battery production or research in Skellefteå will shape Sweden’s next chapter in green tech. For many in Europe’s business community, Northvolt’s rise and fall has become a case study in the risks and rewards of building a new industrial sector from the ground up.
