In a landmark step toward maritime decarbonisation, the Swap2Zero project has received €40 million in funding to construct a 400-passenger, zero-emission cruise ship. Designed to operate for 30 days using renewable and alternative fuels, the vessel will combine wind and solar power with renewable hydrogen (RFNBO) and liquefied methane.
This innovative ship is expected to cut greenhouse gas (GHG) emissions by 80%, preventing approximately 105,000 tonnes of CO₂ emissions.
Pioneering Clean Propulsion Technologies
At the heart of the Swap2Zero vessel lies a combination of cutting-edge energy systems. It will feature both Proton Exchange Membrane (PEM) and Solid Oxide Fuel Cells (SOFC), delivering a total power output of 2 MW showcasing the scalability of high-power fuel cells for large vessels.
Around 50% of the ship’s propulsion energy will come from a Wind Assisted Propulsion System, complemented by over 1,000m² of photovoltaic panels integrated into its structure and sails. These systems will allow the ship to sail efficiently while drastically reducing reliance on fossil fuels.
Integrated Energy Efficiency and Carbon Capture
Beyond propulsion, the ship’s energy management will prioritise efficiency and sustainability. A low-temperature fuel cell operating on liquid hydrogen will power propulsion while recycling the heat and water produced. Meanwhile, a high-temperature fuel cell will meet onboard “hotel” power demands, using recovered heat to produce hot water.
To further boost environmental performance, onboard carbon capture technology will be integrated with the high-temperature fuel cell, capturing emissions directly during operations. A bespoke energy management system will control and distribute power seamlessly, ensuring the vessel operates without traditional generators.
The Swap2Zero project represents a bold vision for the future of maritime travel one powered by renewable energy and advanced clean technologies. By integrating wind, solar, hydrogen fuel cells, and carbon capture systems, the initiative not only showcases the potential for large-scale zero-emission shipping but also positions Europe as a global leader in sustainable marine innovation.
