Our Solutions
Green Anchorage Zones
At any given point, more than 6500 vessels globally are idle at roughly 200 anchorages, emitting over 25 million tons of CO2 and associated particle pollution.
In the face of the challenges surrounding the green transition for the maritime sector, our vision for Green Anchorage Zones emerges as a concrete solution to a complex problem. What sets our approach apart is not just the promise of healthier seas and cleaner air, but the innovative power and charging technology driving it forward.
Onshore Substation
Distribution Hub
Offshore Power and Charging Station
Vessel Connector Cable
Building a network of Green Anchorage Zones offering clean energy to vessels at anchor is integral to our vision. Our ambition to build a network of Green Anchorage Zones in partnership with a broad range of stakeholders underscores our commitment to sustainability and innovation. Our approach is rooted in our innovative offshore power solutions that enables a transition to offer clean electricity in Green Anchorage Zones.
Green Anchorage Zones will enable vessels to receive power directly from a clean energy source or the grid through Stillstrom offshore power solution whilst idling, and thereby substituting the use of fossil fuel or valuable e-fuels. Stillstrom concepts and solutions are designed for safe and operational ease, and centered around a set of key benefits.
Multiple Charging & Power Stations
Our green anchorage zone offers multiple charging points through a centralised hub. The green anchorage zones will be developed in a controlled and regulated fashion, respecting other users of the ocean.
Safe & Reliable Solutions
Our concepts are designed with safety and operability at its core and include options for safe mooring and weathervaning. Stillstrom is further aligning closely with shore power developments, and actively work towards industry standardisation.
Enabling Direct Electrification
Our solutions facilitate connection to the shore grid or direct electrification, ensuring a reliable, sustainable, and constant power source for vessels at anchor. It further allows vessel owners to utilise direct electrification whenever idling, and thereby achieving the most economically feasible route to a decarbonised operation compared to other means of decarbonisation.
Do you have questions about green anchorage zones?
We've compiled answers to the most frequently asked questions to help you understand the benefits and implementation.
What are Green Anchorage Zones?
Green Anchorage Zones is a concept developed by Stillstrom and will be designated areas in anchorage where vessels can anchor and connect to Stillstrom’s sustainable power solutions instead of running their engines while idle. These zones are equipped with advanced power and charging stations that provide clean energy, reducing emissions and environmental impact while the vessels are not actively sailing.
What vessels are applicable?
A wide range of vessels can benefit from Green Anchorage Zones, including container ships, bulk carriers, oil tankers, support vessels, cargo ships and other commercial vessels that spend time idling offshore. Any vessel that needs to maintain power while idling to cover its base and hotel load can utilize the sustainable energy solutions provided by Stillstrom’s Green Anchorage Zones.
In addition Stillstrom is actively working towards standardisation that is aligned with shore power standardisations. This enables vessels ready to receive shore power to also receive offshore power whenever idling.
Where will the power come from?
The power supplied in Green Anchorage Zones typically comes from the onshore power grid, but could potentially also be coming from renewable energy sources such as wind, solar, and other offshore energy installations. This ensures that the energy used is sustainable, significantly reducing the carbon footprint compared to traditional fossil fuel-powered generators.
How will charging work?
Charging and power delivery in Green Anchorage Zones is facilitated through a specialized connection system designed for maritime use. Vessels will hook up to the offshore power grid using secure, water and weather-resistant cables and connectors, ensuring a safe and efficient transfer of power. This system is monitored and managed to provide consistent and reliable energy to the anchored vessels.
What are the benefits of a Green Anchorage Zone?
Green Anchorage Zones offer several benefits:
- Environmental Impact: Reduced emissions and lower environmental footprint due to the use of renewable energy.
- Cost Efficiency: Lower fuel costs and maintenance expenses for vessels as they rely on cleaner, cheaper energy sources.
- Regulatory Compliance: Helps vessels meet stringent environmental regulations and standards.
- Operational Efficiency: Provides a reliable source of power, ensuring that essential systems remain operational without interruption.
What if the vessels are already utilizing green fuels?
Even vessels already utilizing green fuels can benefit from Green Anchorage Zones. Hooking up to offshore power allows these vessels to further reduce their fuel consumption, maximizing their environmental sustainability. Utilising direct power from electricity is further more cost efficient than utlising valuable e-fuels, thereby providing a cost-effective alternative for maintaining vessel operations while anchored.
