Ponant Unveils Swap2Zero: Next-Gen Near-Zero Emissions Cruise Ship by 2030

France-based luxury cruise operator Ponant has unveiled its ambitious vision for sustainable maritime travel with the announcement of the Swap2Zero project, a next-generation cruise ship designed to achieve near-zero emissions. This groundbreaking initiative, co-funded by the European Union's Innovation Fund and the France 2030 program, is set to redefine the cruise industry with cutting-edge technologies and a strong commitment to environmental responsibility. The vessel is expected to set sail by 2030, offering an intimate, high-end experience for 400 passengers while pioneering unparalleled advancements in decarbonization.

Integrated Technologies Powering Swap2Zero

The Swap2Zero project is centered around the integration of six advanced decarbonization technologies, creating a comprehensive energy system aimed at minimizing greenhouse gas emissions. Key components include:

• Wind-Assisted Propulsion: A sail-based system designed to supply approximately 50% of the vessel's propulsion energy using wind power.
• Solid Oxide Fuel Cells (SOFC): Provided by U.S.-based Bloom Energy, these high-efficiency fuel cells generate electricity from liquefied natural gas (LNG), emitting significantly less CO₂ than traditional systems.
• Proton Exchange Membrane (PEM) Fuel Cells: Operating on liquid hydrogen, these fuel cells provide zero-emission propulsion, with heat and water byproducts recycled for onboard use.
• Marine Carbon Capture (MCC): Developed by French engineering firm GTT, this technology captures CO₂ from exhaust gases for onboard storage or reuse.
• Integrated Solar Panels: More than 1,000 square meters of photovoltaic panels, including eco-designed organic solar devices, are embedded into the ship's structures and sails.
• Energy Management System: A bespoke system optimizes onboard power distribution, eliminating the need for auxiliary generators and increasing efficiency through cryogenic LNG energy recovery.

This multifaceted approach is expected to reduce greenhouse gas emissions by 80%, with a target of achieving carbon-neutral operations during navigation, maneuvering, docking, and anchoring, all dependent on fuel availability and routing conditions. Across the ship’s lifecycle, the Swap2Zero initiative aims to avoid approximately 105,000 tonnes of CO₂.

Sustainability and Research Initiatives

As part of Ponant's broader decarbonization efforts, the 2024 Sustainability Report highlights progress made so far, including a 14% reduction in CO₂ emissions per cruise day compared to 2018 levels. This achievement is a stepping stone toward Ponant's climate objectives of a 30% reduction by 2030 and Net Zero emissions by 2050. Other notable efforts include:

• The elimination of single-use plastics onboard, preventing 20 tonnes of waste annually.
• 100% onboard waste sorting, with collaborative port initiatives aiming to recover 50% of waste by 2026.
• An increase in water self-sufficiency through onboard systems that produce drinking water from seawater.

Complementing its environmental focus, Ponant’s ships also function as floating research platforms through the Ponant Science program, launched in 2021. With over 230 researchers hosted and 10 studies published, the program has supported projects focusing on climate change, biodiversity, and pollution research in remote ecosystems. Notable missions have included arctic environmental surveys and the study of seagrass habitats in Polynesia.

"With four additional ships hosting scientific missions, we have increased the number of research projects and broadened our geographical reach; 2024 marked a real turning point," said Dr. Megan Clampitt, Ponant's head of science.

Public-Private Collaboration and Industry Impacts

The Swap2Zero project is being developed in partnership with innovative firms, including Bloom Energy and GTT. These collaborations highlight the growing trend of public and private entities coming together to advance sustainability in the maritime sector. The €40 million grant secured from the European Union Innovation Fund marks a significant investment in fostering carbon neutrality.

Mathieu Petiteau, Ponant’s Director of New Constructions and R&D, emphasized the importance of partnerships in decarbonization. "This partnership is a key milestone in developing innovative and efficient ways to capture CO₂ and embodies our commitment to finding new solutions to decarbonizing the maritime industry."

Bloom Energy's Chief Commercial Officer Aman Joshi added, "This initiative exemplifies how innovation and collaboration can accelerate the transition to cleaner, more sustainable shipping."

The hybrid technologies deployed on the Swap2Zero vessel are expected to establish a new benchmark for the global cruise industry. Industry experts predict that these systems could be adapted for use beyond cruising, potentially transforming cargo shipping, scientific vessels, and luxury yachts.
