High-Efficiency Fuel Cell Power Systems for Large Scale Maritime Vessels

transportTestedTRL 7

Imagine a giant battery that doesn't just store power but creates it cleanly using fuel, while also capturing the heat it produces to warm the ship. Instead of burning fuel in a loud engine, it uses a chemical process to make electricity more efficiently. It's like upgrading a ship's old boiler and engine to a smart, clean energy plant that can run on various types of green fuels.

The business problem

What needed solving

Shipping companies face strict IMO and EU 'Fit for 55' mandates to slash GHG emissions. Current internal combustion engines are too inefficient and polluting to meet these 2030 and 2050 targets.

The solution

What was built

A 500 kW solid oxide fuel cell (SOFC) module integrated into a cruise vessel, supported by an 80 kW scaled-down experimental module.

Who can put this to work

Cruise Shipping
enterprise
Target: Cruise line operator

If you are a cruise line operator dealing with strict EU emission targets and high fuel costs — this project developed a 500 kW solid oxide fuel cell that can scale to 20 MW. This technology can lead to over 23% total fuel savings compared to standard internal combustion engines.

Offshore Services
mid-size
Target: Offshore vessel operator

If you are an offshore vessel operator dealing with the need for reliable, low-emission power in remote waters — this project developed a fuel-flexible SOFC system. It is designed to work with carbon-neutral fuels and is being tested for specific duty cycles of offshore vessels.

Maritime Engineering
enterprise
Target: Shipyard and naval architect

If you are a shipyard dealing with the challenge of integrating new green energy sources into ship hulls — this project developed a fully integrated spatial, electrical, and thermal SOFC module. It provides a roadmap for scaling these systems up to 10 MW and beyond.

Frequently asked

Quick answers

What is the expected cost or price of the system?

Based on available project data, specific pricing or cost per unit is not provided.

Can this technology be scaled for very large ships?

Yes, the project demonstrates scalability to 10 MW and beyond, with a specific target of upscaling to 20 MW in ocean cruise liners by 2029.

How is the intellectual property or licensing handled?

Based on available project data, there are no specific details regarding IP or licensing agreements.

When will the technology be ready for full commercial use?

The project aims for TRL 7 by June 2027, with extended field testing planned to reach TRL 8 by 2028-2029.

How does this integrate with existing ship systems?

The system is designed for full integration spatially, electrically, and thermally into the ship's design, operating in a combined heat and power mode.

Consortium

Who built it

The consortium is heavily industry-driven with a 77% industry ratio, comprising 10 industrial partners including 3 SMEs. With 13 partners across 6 countries (DE, FR, MT, NL, NO, UK), the group covers the entire value chain from research (DLR) to field implementation, ensuring the technology is developed for real-world commercial application rather than just academic study.
