Stillstrom, a Maersk subsidiary, has introduced two new vessel charging systems for offshore wind farms to address the offshore power supply challenge. The company launches the Power Hub and Power Tower, two autonomous systems that enable vessel charging without direct dependence on turbine infrastructure.
Offshore wind farms are increasingly located farther from shore, and the vessels that install, maintain, and repair them require electricity, but today they use polluting fossil fuels. In fact, emissions from these vessels represent the largest source of CO₂ in offshore wind farm operations.
Power Hub and Power Tower
On one hand, the Power Hub is designed as a compact structure that can be added to existing wind farms without modifying the existing infrastructure. On the other hand, the Power Tower mimics the shape of turbine foundations, allowing installation with the same vessels and tools already in use, and is designed for new wind farms.
Both solutions will enable vessels to connect to the wind farm’s electrical grid, reducing dependence on marine fuels and decreasing greenhouse gas emissions.
Expansion of the Company’s Portfolio
For his part, CEO Kristian Borum Jørgensen emphasizes that Stillstrom’s mission is to eliminate vessel emissions. To achieve this, he considers it essential to deploy offshore electrical infrastructure that accompanies offshore wind energy growth. These new solutions are part of a broader strategy to consolidate its leadership in maritime decarbonization.
The company will present these innovations at WindEurope 2026 in Madrid. This event will be key to demonstrating how its solutions can be integrated into real projects and scaled within the offshore energy sector.
