Battery manufacturer Lyten has announced plans to build an AI data center in Gdańsk, Poland.

The facility will form part of a wider industrial hub planned for the port city designed to service the AI, defense, and energy infrastructure sectors.

Lyten did not release details on how large the data center will be, its tenants, estimated construction cost, or how it will be powered. DCD has approached the firm for comment.

“We are entering a new era of infrastructure development to support the multi-decade growth in power demand, AI data centers, and defense spending,” said Dan Cook, Lyten’s CEO and co-founder, in a statement. “Lyten is establishing strategically located industrial hubs to combine Lyten’s advanced materials and battery energy storage systems with digital AI infrastructure. We believe that Poland has the right talent, the right infrastructure, and the right appetite for public-private partnerships to enable a Lyten Industrial Hub to thrive in Gdańsk.”

Lyten’s new industrial hub will be built around Lyten Dwa, its battery energy storage system (BESS) factory on the outskirts of Gdańsk.

Formerly known as Northvolt Dwa, Lyten acquired the 270,000 sq ft (25,000 sqm) plant in October 2025. The firm said a feasibility study will be conducted this year to analyze the requirements for future manufacturing facilities at the site, as well as new energy infrastructure.

Lyten Poland’s CEO, Robert Chryc-Gawrychowski, said that the provision of an AI data center on-site, too, would bring much-needed capital investment for the scheme.

“Manufacturing creates much-needed jobs, but requires significant capital investment,” said Chryc-Gawrychowski. “AI data centers bring in huge investment and capital, but do not drive significant employment growth. By combining these two elements in our industrial hubs, we deliver the benefits of both [worlds] and at the same time future-proof the local economy as AI continues its disruptive growth.”

Gdańsk is located in the north of Poland, bordering the Baltic Sea. It has a small data center presence with three facilities listed by DataCenterMap. Most of Poland's data centers are located in and around Warsaw.

Founded in 2015, Lyten manufactures lithium-sulfur batteries and advanced materials. In August 2025, the firm acquired all of the former Swedish battery producer Northvolt’s manufacturing sites in Poland, Germany, and Sweden.

Lyten’s plans for an industrial hub in Gdańsk, Poland mirror its plans for a similar site in Skellefteå, Sweden. There, another campus will be built out of the former Northvolt Ett plant, encompassing a 1GW data center built in collaboration with EdgeConneX and a battery production plant.
