World’s First Hydrogen Boat - Energy Observer

This is the energy observer, the first autonomous hydrogen boat to sail the seas.
Powered by solar, hydrogen, wind and water energy, the white catamaran will take six years to tour the world.
During its stopovers, Energy Observer produced a total of 488 kg, almost ½ ton of hydrogen, during 1496 hours of functioning, that's an efficiency of 42%.
Hydrogen supplied up to 60% of the energy needed for a typical voyage, and the remaining 40% was attributed to solar power, using a fuel cell functioning on average for 6 of each 24 hours of navigation, with an efficiency of 48%.
On the sides of the boat are The Oceanwings wings which are going to reduce the vessel's energy consumption, accelerate its speed, and above all, enable it to produce energy and hydrogen while navigating.
