What is claimed to be the cruise industry’s first hybrid powered ship is due to be delivered in the summer of 2023.

To be operated by Royal Caribbean Group’s (RCI) ultra-luxury brand, Silversea Cruises, the new class of ships, known as ‘Project Evolution,’ will run on three power sources – a  fuel cell system, battery technology and dual fuel engines using LNG as the main fuel.

This hybrid solution, using fuel cell technology, allows the ship to be emissions free while in port.

“Silversea’s newest ship class is a significant leap forward in our commitment to sustainable ship design and our journey to reduce our environmental footprint,” said Richard Fain, RCI’s Chairman and CEO.

“We first announced our fuel cell ambitions several years ago. Through dedication and perseverance, we are now proud to introduce the first ship with large-scale fuel cell technology capable of achieving emission-free port operations.

“Incorporating fuel cells into our ships now is one example of how Royal Caribbean Group is preparing to use new technologies as we move to a non-carbon-based future. This pioneering approach builds on our spirit of innovation,” Fain said.

This new hybrid technology not only helps in port, but also allows ‘Project Evolution’ to achieve a 40% overall reduction in its greenhouse gas emissions (GHG) per double occupancy,  compared to the brand’s previous class of ships.

The design is also projected to achieve an Energy Efficiency Design Index (EEDI) rating around 25% better than applicable IMO requirements.

“Being at the forefront of sustainable shipping design and innovation is a testament to our team’s drive for continuous improvement,” said Roberto Martinoli, President and CEO, Silversea Cruises. “These advancements support our desire to showcase the world to our guests and to do so in a mindful and environmentally responsible way.”

‘Project Evolution’s’ initiatives, developed in partnership with Meyer Werft, will bring energy efficiency to a new level and will include both first-of-its-kind initiatives and successful features previously introduced, such as:


  • Fuel Cell System– a hydrogen-based technology, which will supplement the main power supply and carry the ship’s total hotel load — up to 4 MW— the first large-scale fuel-cell installation at sea in the cruise industry.
  • LNG – a cleaner burning fuel, LNG-fuelled propulsion systems emit less CO2 and 97% fewer particulates than normal fuel oil used on ships.
  • Battery – a bank of batteries supports optimising the overall ship power system, saving fuel.
  • Waste to Energy – newly developed Micro Auto Gasification System (MAGS) reduces on board waste volume, resulting in lower incineration emissions.
  • Towards Carbon Neutral Construction – in partnership with Meyer Werft, ‘Project Evolution’ is designed and built to take into consideration the carbon footprint of ship construction and creating a path to overall reduction.
