This is an Energy Observer the first ever autonomous hydrogen boat to serve the sea. This former race boat has been fully transformed into a vessel that produces zero emission of greenhouse gases or fine particles. This boat uses a mixture of renewable energy sources such as solar panel, wind turbines, and hydrogen. The energy generated is stored in Lithium Ion batteries which are used for on-demand power and most importantly for electrolysis of water.

Started the journey in 2017, the Energy Observer has partnered with hydrogen technology pioneer – Toyota Motor. Truly, both companies share similar goals on climate change.

“We are really excited to have Toyota Motor Europe on-board for this mission. We share the vision of hydrogen as the key for accelerating energy transition, a vision that we wish to carry to the 2020 Olympic Games in Tokyo.”

Victorien Erussard, Founder and Captain of Energy Observer

As of May 2019 the voyage is on its 36 stopovers at Hamburg and is set to complete Northern Europe by end of 2019. The goal of the journey is to sail to 50 countries with 101 stopovers in a span of 6 years.

The vessel built in Canada in 1983, sits at about 30.5 m length and functions using solar, wind, ‘green’ hydrogen, and recently installed wind propulsion wings. The hydrogen an abundant element does not occur naturally in nature. So, the ‘Green” hydrogen is produced using electrolysis which is a process where electricity is used to split water molecules in hydrogen and oxygen.

Energy Observer Hydrogen Tanks

On the vessel, there are 8 tanks constructed of aluminum and carbon fiber. The tanks have the capacity to hold 62kg of hydrogen in a gaseous state. The stored hydrogen is used to power the electric motor for propulsion when needed.


  1. How does a gas power an electric motor ? The stored hydrogen is used to power the electric motor for propulsion when needed.

  2. It has to be used in any modified engine hooked to the generator The best method I found is using a car engine with a chip to modify the timing to accommodate the earlier explosion of the hydroxy gases. The electrolyzer giving the most gas is a tube-in-tube one. The secret to it is the same as the plate type used in speed boats for years; anchor the tubes to prevent touching. When you put 42.7 kHz at 12v DC across the tubes, they get hot & vibrate. But this allows the immediate use of the gases without storage. The collection of filtered rain is used for storage. This system gives electricity at 7 cents per kWh, and vehicle fuel for 2 cents a mile, compared to gas or Diesel at 10 to 20 cents per mile. Even if you have an electric vehicle, the cost per mile is 7 cents. That works out to 30% of the cost of fossil fuel with no pollution. You also get the engine to last longer, have half the number of synthetic oil changes and you get more power..
