The team started in august with designing a flying hydrogen-powered boat. 26th of January we presented this design. Since then the team has been working hard to realize this design, to make a digital idea reality. In just 5 months we produced a brand new hull from scratch, we have turned and milled a lot of parts, we soldered our custum design pcb’s and wrote a lot of code to make al these separate parts work together. It is so exciting to see our hard work pay-off and the team is thrilled so present our flying hydrogen-powered boat.
This May 23rd the time is finaly there, our hydrogen-powered boat will be revealed! In addition to revealing our boat to the public for the very first time, she will be christend by Raoul Boucke aswell.
Location: Lake7, zevenhuizen
Time and date: May 23rd, 14.00 till 18.00

Here you can find the design of the flying hydrogen-powered boat of 2022. Spin around the model youself and read about the detail of our design.
The beating heart of our boat
The beating heart of our boat is our fuel cell, but to understand how our fuel cell actually works, we need to take a closer look at hydrogen itself. Hydrogen is an atom, an element. A hydrogen molecule consists of two atoms. You see two protons and two electrons.
Hydrogen goes from the tank to the fuel cell and passes through the proton exchange membrane. This is like a filter that only allows protons to pass through, but it blocks the electrons. That’s why, when a hydrogen molecule reaches the proton exchange membrane, it splits up into two protons and two electrons. The protons then pass through the filter to join an oxygen atom on the other side to form water. Because of the membrane the electrons have to travel through an external circuit, producing a direct current. However, we are not just letting it go through any ordinary external circuit, we are powering our boat with this!
A FLYING hydrogen-powered boat
Besides building a hydrogen-powered boat in just one year, we also make it fly! When a boat picks-up more speed, the drag with the water increases leading to more energy usage. By making our boat fly we avoid using those big amounts of energy, making our boat much more efficient. When sailing the foils create an upwards force, known as lift. When sailing faster, the foils create more lift. The foils and the struts lift the boat out of the water when we reach our take off speed of 25 km/h
The waves we face when we fly on the ocean influence the balance of our boat. That’s why we actively control our foils with a height control system. We have three sensors that constantly measure the height and orientation of our boat. That means that, when our starboard side drops ever so slightly, our sensors measure this and tell the starboard foil to adjust its angle of attack: generating more lift and re-balancing our boat. This way we can stably fly for extensive periods of time.
Just like many other boats we use a propellor to move forward. However with our struts and wings underneath the boat the mechanism connecting the propellor to our electro motor is quite complex. The propellor has to be at the end of the strut so it will always be submerged even when we are flying. The electro motor however cannot fit in this strut. This make the usage of a driveline necessary. The driveline translates the rotating of the electro motor down the strut into the propellor, making it spin. This is how we can keep moving forward even when we are flying.
