Fieldfisher's Poland team has advised US company Lyten Inc. on the acquisition of Northvolt Dwa ESS, Europe’s largest energy storage systems manufacturing operation, located in Gdansk, Poland.
In March 2025, Swedish battery developer and manufacturer Northvolt AB filed for bankruptcy, representing the largest bankruptcy in modern Swedish industrial history. At the time, Northvolt's assets in Poland included a 25,000 square meter battery energy storage systems (BESS) manufacturing and R&D facility. The Gdansk Dwa ESS facility came online in 2023. The facility includes equipment to ramp up to 6 GWh of energy storage manufacturing capacity and the footprint to expand to 10+ GWh in the future. The facility is supplied by renewable power and has contracted orders extending into 2026.
Lyten intends to immediately restart production in Gdansk to resume sales. The transaction complements Lyten’s previously announced acquisition of Northvolt’s lithium-metal cell manufacturing facility in Silicon Valley to scale its lithium-sulfur battery production.
Lyten is a supermaterial applications company and global leader in lithium-sulfur batteries. The company was founded in 2015, and has received more than USD 425 million in equity investment and secured LOIs for USD 650 million in financing from the Export Import Bank of the US. Lyten has built a proprietary materials platform, called Lyten 3D Graphene, that it uses to build better performing, lower cost, and decarbonizing products, including its next generation lithium-sulfur battery. Lyten's corporate headquarters is in San Jose, CA with European headquarters in Luxembourg.
Fieldfisher's team was led by Co-Managing Partner Rafał Stroiński and Senior Counsel Andrzej Zając and included Counsels Bogdan Duda, Malwina Niczke-Chmura (both Corporate), Magdalena Kalińska (Banking & Finance) and Jan Sarnowski (Tax); Senior Associate Magdalena Borychowska (Corporate); Associates Małgorzata Nowak (Corporate) and Adam Janczewski (Banking & Finance); and Junior Associate Eryk Ryciak (Corporate).
Rafal Stroinski advises, "In the race to power the world in a most environmentally friendly way, the US has been making incredible efforts to be the market leader. Therefore, this project is not only key to our client Lyten's growth, but to US involvement in the electric battery sector, and for Poland to be one of the main players on the manufacturing market. We congratulate all parties on this transaction, which allows the Gdansk operations to continue, and to our client Lyten for trusting us to support them."
Andrzej Zając says: "The Polish green energy market continues to surpass expectations, aligning to the world's needs and ambitious targets. We are proud that the very best players on the market trust Fieldfisher's team, and that we can contribute to the energy transformation charge, in so doing making the world a better place."
