Ponant, a cruise operator, has unveiled plans to construct a hybrid passenger cruise ship, Ponant Swap2Zero, incorporating wind, liquid hydrogen (LH2), and bio-liquefied natural gas (bio-LNG) for power generation. This initiative is part of Ponant's commitment to advancing maritime travel towards carbon neutrality. The vessel, approved in principle by Bureau Veritas, features a sail power system, 1,000m² of solar panels, liquid hydrogen fuel cells, high-temperature fuel cells for hotel loads, and onboard carbon capture technologies. Ponant's Newbuilding and R&D Director, Mathieu Petiteau, describes the vessel as a representation of their vision for the next generation of cruise ships, showcasing a harmonized blend of technologies and energy sources while ensuring compliance with regulations. The eco-friendly vessel, designed for transoceanic travel, emphasizes energy efficiency, autonomy, and the use of renewable resources to minimize emissions. It integrates wind propulsion, solar energy, hydrogen fuel cells, and renewable fuels like e-methane and bio, aiming to be nearly emission-free. The Swap2Zero project has received AiP and adheres to international standards like SOLAS, ILLC, MARPOL, and the IGF Code. The vessel's sustainable design enables up to 50% wind-assisted propulsion and a month of autonomous operation. It incorporates solar panels, Proton Exchange Membranes (PEM), Solid Oxide Fuel Cells (SOFC), batteries, and renewable liquid hydrogen for clean energy. The ship's dual-fuel engines are capable of using biodiesel and biogas, meeting Safety of Return to Port (SRtP) requirements. Notably, the vessel's cutting-edge carbon capture system captures and stores CO2 emissions, contributing to environmental preservation. By integrating waste heat and cold recovery technologies, the Swap2Zero initiative aims to set a new standard for environmentally responsible marine operations, focusing on energy efficiency and sustainability.
