Two Danish companies are exploring the integration of offshore wind with marine electrification to reduce vessel-related greenhouse gas emissions. Stillstrom, a leader in marine technology, aims to provide offshore power and charging solutions for battery powered vessels. A joint white paper with the Port of Roenne on the Danish island of Bornholm will explore how offshore wind can support charging solutions for electric ferries and cargo vessels. Bornholm, designated as an energy island, is central to one of the busiest shipping corridors in Europe and plans to build offshore wind farms to support maritime electrification. The concept of "energy islands" as hubs for offshore power transmission is discussed, with estimates of 17 terawatt-hours of electricity needed for battery-powered vessels. This transition could save €2 billion in oil imports and reduce marine gas oil emissions. The Port of Roenne sees itself as well-positioned to contribute to the infrastructure needed for maritime electrification, including ferry and cruise vessel charging. Energy Island Bornholm is seen as a valuable opportunity to understand future maritime energy needs and support the wider transition to clean energy in Europe's shipping corridors.
