French mobility start-up SeaBubbles unveiled the world premiere of their life-size version of the SeaBubble, an electric flying boat powered by hydrogen, at the recent Cannes Yachting Festival. Committed to overcoming environmental issues in the field of nautical mobility, SeaBubbles have designed a zero-wave, zero-noise, zero-emission navigation experience for passenger transport.

Responding to the rapid transformation of mobility and inspired by innovations in the naval, automotive and aeronautical industries, SeaBubbles define a new generation of boats, which are designed to offer an unprecedented, futuristic, nautical experience, while preserving the natural ecosystem.

Powered by a hybrid system composed of hydrogen fuel cells and an electric battery pack, and combined with automated and retractable foils, the SeaBubble offers two and a half hours of autonomy, allowing 50 nautical miles (90km) to be covered at 18 knots with only 4 minutes of recharging in an H2 station (3 x 3.2kg of hydrogen at 350 bars). With a length of 8m and a width of 3.5m, the SeaBubble accommodates up to 12 passengers, depending on the configuration.

Virginie Seurat, General Manager of SeaBubbles, explained: ‘The mobility sector, which accounts for more than a third of worldwide emissions, is currently shifting towards more responsible solutions. Transforming mobility on land, water and in the air is a major environmental challenge if we want a world that is fit to live in. We are supporting the energy transition in our sector by offering a new cleaner and more energy-efficient type of watercraft that uses foils and hydrogen.’

The innovation of SeaBubbles is strongly tied with supply infrastructures and goes hand in hand with the development of a hydrogen industry and local ecosystems to which it contributes. In spring 2023, SeaBubbles will unveil the first pilot line and the real-life test phases will begin.
