The World's fastest hydrogen powered yacht



TRIMARAN YACHT - The Elizabeth Swann has one long central hull and two shorter outriggers, as a custom build. The aim being to cut drag as far as possible, in a relatively low cost design. But then, any custom build is going to be more costly. Don't let this put you off converting something off the shelf. This is just an example. Start with a blank drawing board (as per the above), or with the boat moored in your Marina. Lots of yachts are abandoned in harbours. That might be a good starting point. If you can get a free hull!







There is no limit to the design of vessels that are entered into the JVH2 World Hydrogen Trophy series of ocean racing events, inspired by the legendary Jules Verne. You can enter a boat, yacht or ship. These can have a single hull, or multiples of hulls, such as a twin hull catamaran arrangement, or a triple hull trimaran configuration.


It is Open Class.


You can have a displacement hull, deep V, wave piercing, or foil design. The vessel can be any length or displacement. It is an unlimited category. More than likely, the cost of producing your entry will play a major part in deciding how to proceed, as will physics and logistics.

The one limitation that competitors must work to, is using hydrogen to power their entry. This can be a compressed gas, liquid hydrogen, ammonia, methanol, or peroxide. So long as the fuel used is derived from hydrogen. Preferably, green hydrogen, produced from a renewable energy source.








HAVILA VOYAGES - Offer battery powered cruises in Norway, with generators powered by natural gas. That is not, a million miles away from using hydrogen as the fuel. So, well done to Havila.


Havila Voyages’ operate four coastal cruise ships. They are loaded with the largest battery packs ever installed on a passenger ship, meaning that we can sail for four hours straight with zero emissions. That way you can visit vulnerable fjords, such as the world heritage Geirangerfjord, without worrying about environmental issues, and you can do so in utter silence. The battery packs, which are supplied by Corvus, weigh 86 tons, and they have a capacity of 6.1 megawatt hours.

The batteries are charged with clean hydropower ashore, and when we don’t use the batteries, we run on LNG (liquid natural gas) which – along with general efficient hybrid operation – cuts CO2 by around 40 per cent. NOx emissions are reduced by 90 per cent. With the gradual blending of biogas, emissions of CO2 can be reduced to 50 % in 2023 and 80 % in 2024.

HYDROGEN READY - Havila Voyages´ ships have been designed to ensure that when hydrogen becomes a viable power approved for commercial sailing, the vessels can be converted into using the latest technology. Havila Voyages´ coastal cruise vessels are part of a pilot scheme by Hav Design called “FreeCo2ast”. 
We wonder if they might one day be a 'JVH2' World Hydrogen Trophy contender, in a cruise category.

The vessel may have a battery in the circuit for buffering, or charged via a fuel cell from any of the above sources.


You can use the fuel to power an internal combustion engine, or use fuel cells and electric drives. 


A hydrogen IC engine can power a generator, thence hybrid drive to electric pods. By way of example.


Part of the challenge is to determine if IC engines can be adapted from fossil fuel usage, to compete effectively with electric motors. For sure IC engines are cheaper and the technology is available off the shelf. Many are already fitted in vessels that could race tomorrow (with some engine modifications), given the financial backing to support an ocean racing team.


This raises the issue of bunkering. Where at the moment, many ports and harbours do yet not supply hydrogen fuels. So plan your course carefully. It is a logistical as well as a nautical challenge.
