The new class of ship, known as Project Evolution, forms part of Silversea’s parent company Royal Caribbean Group’s move to create a more sustainable fleet of vessels.
Project Evolution will see new Silversea ships powered by three energy sources: a fuel cell system to supplement the main power supply, battery technology and dual fuel engines, which use liquefied natural gas (LNG) as their main fuel.
This hybrid approach will allow ships not to create any local emissions in port with the fuel cells providing the ship’s power, while also reducing greenhouse gas emissions by 40% per double occupancy, compared with Silversea’s previous class of ships.
Richard Fain, chief executive of Royal Caribbean Group, said: “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.
“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.”
Silversea’s new ship class is also set to achieve an Energy Efficiency Design Index (EEDI) rating around 25% better than the requirements of the International Maritime Organization (IMO).
“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,” added Fain. “This pioneering approach builds on our spirit of innovation.”
Royal Caribbean Group has already been working on other technologies to enhance energy efficiency, waste treatment and water management.
“Being at the forefront of sustainable shipping design and innovation is a testament to our team’s drive for continuous improvement,” added Roberto Martinoli, Silversea’s chief executive.
“These advancements support our desire to showcase the world to our guests and to do so in a mindful and environmentally responsible way.”
