ALL-DC-SHIPS

The maritime sector is undergoing a major transformation to meet global climate targets. With shipping responsible for around 2.5% of global emissions, the push toward low and zero-emission vessels is more urgent than ever. The International Maritime Organization (IMO) has set ambitious goals: a 20% emissions reduction by 2030 and net-zero emissions by 2050.

Our Mission

ALL-DC-SHIPS is a €10.2 million Horizon Europe-funded project, led by the University of Birmingham, that brings together 12 partners from 8 European countries. Our goal is to revolutionise shipboard power systems by developing and demonstrating a fully direct current (DC) electrical architecture – from propulsion to auxiliary systems.

Why DC?

While some vessels have adopted DC primary grids, secondary systems still rely on traditional AC setups. ALL-DC-SHIPS introduces a complete DC solution, improving energy efficiency, reducing fuel consumption and simplifying integration of renewable energy and storage. This approach enhances reliability, reduces blackout risks, and supports the transition to climate-neutral shipping.

What We’re Building

The project will deliver a working prototype of a vessel powered entirely by DC systems. Key innovations include:

• Modular DC/DC converters with wide bandgap semiconductors
• Solid-state protection devices for fast fault isolation
• Advanced energy management algorithms for optimal performance
• Secondary 400 V DC grid and high power auxiliary loads (e.g. pumps, fridges, kitchens, etc.) 
• 24/48 V DC grid for low power auxiliary loads (e.g. navigation, automation, communication, and control equipment) 
• Plug and play integration for faster commissioning and cross-vendor compatibility

A Step Toward the Future

ALL-DC-SHIPS will validate these technologies through real-world testing on a 3000 GT dredger, followed by scalability studies for larger vessels such as cruise ships and cargo carriers. The anticipated impact includes verified fuel savings, improved system reliability, and a clear pathway for industrial adoption.

By combining cutting-edge engineering with practical implementation, ALL-DC-SHIPS is laying the foundation for the next generation of sustainable maritime transport.
