HYDROGEN LIMOUSINE MODEL L
SeaBubbles presents its unique water shuttle, the Hydrogen Limousine model L flying above the waters.
Lifted on intelligent stabilizing foils, propelled by electric energy generated by a hydrogen fuel cell. She leaves behind barely any trace on the water surface and not a sound or smell in the air.
Commuting 7 to 8 passengers on regular transit lines at 20 knots (35 km/h) on a 45 nautical miles (85 km) radius, with the motto “Zero Wave, Zero Noise, Zero Emission”.
The Limousine H2 offers an alternative to future mobility as well as a potential for cruising in protected marine areas.
The propelling system and the aerodynamic design of the SeaBubble Limousine H2 come from the naval industry.
The interior design and roof stem from the automobile industry.
The foiling stabilization system originates from the aeronautic industry.
The Hydrogen Limousine model L is the world’s first hydrogen foiler.
The advanced foil-stabilization system that equilibrates the Bubble smoothens the ride and insures the safety of the flight. Foils are profiled to not generate any waves, thus preserving the often damaged river shores. The Limousine can operate in waterways at high cruising speeds where it was impossible until now.
The choice of a hydrogen fuel cell as a source of electricity is the result of in-depth studies on how to make the boat respectful, powerful and light enough to englobe all of her cutting-edge characteristics.
The H2 tanks carry energy to operate for 2hrs 30 min before needing a 4 minutes onshore refill, a yet never experienced feature in the world of electric mobility. Moreover it helps preserving the life of the buffering battery pack.
Choosing SeaBubbles is choosing low-carbon emission transportation as a collective choice.

SeaBubbles has chosen the hybridization between a hydrogen fuel cell and a battery pack.
Fuel cell technologies are a promising road to a greener future, but they often require support for the variation in power needs of the craft thus making a battery -fuel cell hybrid a complete solution.
SeaBubbles engineering team is designing a highly efficient Power Management System. The greatest challenge faced being adjusting the embedded energy to the mass of the ship, so that she can fly !
The management of the power train depends on :
- Operating cycle
- Hydrogen reserves
- State of charge of the battery
