Stillstrom unveils standalone offshore charging systems

The Power Hub and Power Tower introduce standalone options that can be deployed independently of turbine infrastructure, enabling flexible charging across both operational and future offshore wind developments.

The company said they mark the next stage in its offshore charging strategy, broadening its portfolio and increasing flexibility in how and where infrastructure can be deployed, alongside solutions already integrated within windfarm assets.

The launch builds on the work of Stillstrom’s R&D team, with engineers Koen Legrand and Raymond Bergmann recently recognised as Inventors of the Year 2025 by AP Moller – Maersk. This includes multiple patents across its offshore charging technologies, as well as pending protection for both the Power Hub and Power Tower.

Stillstrom detailed engineering manager Koen Legrand said, “Our new monopile systems help to address the sector’s long-standing ‘chicken and egg’ challenge, where vessel electrification and infrastructure deployment must progress in step. 

“The Power Hub is a compact, monopile-mounted structure designed for installation in operational windfarms, enabling charging capability to be added to existing infrastructure. The Power Tower is designed for newbuild offshore wind projects, with a form that mirrors a turbine foundation and allows installation using standard construction vessels, tools and processes, enabling charging to be integrated from the outset.”

Stillstrom chief executive Kristian Borum Jørgensen said, “Our mission is to eliminate vessel emissions, the largest source of CO2 in offshore wind operations. Electrification of SOVs is essential if the wind industry is to meet its full decarbonisation potential. What has been missing is the infrastructure to support it at sea. These new solutions give developers and operators practical, scalable options, enabling offshore charging either fully integrated within wind farm structures or through standalone offshore installations.”
