Offshore wind farms, energy islands, ports and proposed “Offshore Power Zones” could together form the foundation of an integrated maritime energy system capable of supporting large-scale vessel electrification across Northern Europe, according to a study by Maersk’s Stillstrom, Baltic Energy Island and the Port of Roenne.

In a whitepaper titled Bornholm Energy Island: Powering Maritime Electrification, the companies state that combining offshore wind generation with port infrastructure and offshore charging concepts could enable ferries, cargo vessels, and service operation vessels (SOVs) to shift away from fossil fuels on a large scale.
