Passenger Ship Technology's forecast for 2025 highlights the increasing adoption of green corridors in the passenger ship industry. Initiatives like the establishment of green corridors for methanol-fueled ferries are set to become mainstream. Projects such as the DFDS green methanol-fueled ferries between the UK and Netherlands and the Baltic Sea's first green corridor by Viking Line are paving the way for eco-friendly shipping routes. Methanol is also making its way into the cruise ship sector, with upcoming vessels like RCCL's Celebrity Xcel and Disney's Adventure set to use methanol upon delivery in 2025. Furthermore, LNG remains a popular choice for fuel in passenger ships, with new orders and efforts to reduce emissions. The industry is focusing on LNG-powered ships in both the cruise and ferry sectors. In parallel, hydrogen is emerging as a promising alternative fuel. Projects like the first commercial hydrogen fuel-cell ferry and installations of hydrogen fuel cells in cruise ships indicate a growing interest in hydrogen technology. The move towards hydrogen aims to further enhance the sustainability of the passenger ship industry in the ongoing energy transition.
