NETHERLANDS: Air at the port of Scheveningen is cleaner than ever thanks to a new shore supply facility. Thanks to the shore power supply, berthed vessels can shut down their diesel generators and instead buy sustainable power using an app.
The alternative electricity supply eliminates air pollution and reduces noise and vibrations when ship engines are idle. It’s so convenient and popular that on average, the harbor saves 1,000 liters marine diesel daily, resulting in dramatic reductions in air pollution from particulate matter, nitrogen oxides (NOx) and sulphur oxides (SOx) in addition to substantial CO₂ savings.
“The system has been successfully working for two years now, and we’ve had no problems at all with any of the Danfoss components: They’re totally reliable”, explains Maarten Hektor, Managing Director, Involtum
100% renewable energy
The installation of shore power in Scheveningen harbor is a major part of The Hague’s Air Quality Action Plan, which outlines what the municipality is doing together with businesses, residents, interest groups and the Dutch State to further improve the air quality in the city. Of course, only 100% Dutch sustainable wind energy is used in the installation.
Power connection for many vessel types
While shore power in the Second Harbor already existed for cutters, small fishing boats and pleasure vessels, this major new industrial-scale installation in the other two harbors extended capacity to many more vessels.
The new shore supply system serving the First and Third Harbors is a first for the Netherlands in terms of its large scale, its technology, and and its convenience for users. The system was built using a Danfoss VACON® NXC series low harmonic drive to convert grid power to adapt the frequency to the ship’s grids. The system has eight power outlets each with a communication system allowing the ship’s engineer to connect and pay for power using an app.
