Sustainable design is a hallmark of the new Project Evolution cruise ships developed by Royal Caribbean Group in partnership with Meyer Werft Shipyard. The ultra-luxury brand Silversea Cruises hybrid ships will set sail in the summer of 2023 with a trio of power sources.

A hydrogen fuel cell system will supplement the main power supply and carry the ship’s total hotel load of up to 4 MW. Liquefied natural gas will be consumed as the main fuel in dual-fuel engines, eliminating the carbon dioxide and particulate emissions associated with fuel oil. A battery bank will also contribute to power system optimization and reduced fuel use. In addition to this sustainable power solution, the ships feature a micro auto gasification system to reduce onboard waste volume and incineration emissions.

The vessels are capable of achieving emission-free port operations and a 40% overall reduction in greenhouse gas emissions per double occupancy when compared to the previous class of ships. The new ship class is also projected to achieve an Energy Efficiency Design Index rating approximately 25% better than applicable International Maritime Organization requirements.
