The vehicle utilizes a Rotax Twin Cylinder motorcycle engine modified to run on hydrogen. Unlike fuel cells that generate electricity, this engine burns hydrogen directly. The hydrogen is delivered via twin injectors in a manner very similar to a standard fuel-injected petrol engine. The mechanical power is transferred through a drivetrain that includes a chain drive, a drive shaft, and a differential—components typically found in standard cars or quad bikes. This demonstrates that hydrogen technology can be adapted to work with existing internal combustion mechanical architectures.
Professional engineering bodies and automotive associations in Australia provide resources and standards regarding powertrain technology and alternative fuels.
Hydrogen is a 'sparse' gas, meaning its density is very low at standard atmospheric pressure. To store a useful amount of energy in a vehicle, it must be significantly compressed. The tank in this lesson stores approximately one kilogram of hydrogen at 200 bar (200 times atmospheric pressure). Interestingly, this single kilogram of hydrogen contains an energy level equivalent to about three to four litres of petrol. This highlights the high energy-to-weight ratio of hydrogen, but also the challenge of the volume it requires compared to liquid fuels.
Australian scientific research institutions and industry councils are key sources for data on hydrogen properties, storage technologies, and energy comparisons.
Because the hydrogen is stored at a high pressure of 200 bar, it cannot be fed directly into the engine. It passes through a series of pressure reducers and check valves. By the time it reaches the engine injectors, the pressure is reduced to approximately 5 bar (five times atmospheric pressure). Safety is paramount; the system includes automatic safety shut-off valves located at the tank. If a collision occurs or piping becomes dislodged, these valves instantly cut off the hydrogen flow at the source to prevent explosions or leaks.
Government bodies and safety organizations in Australia regulate the handling, storage, and safety standards for high-pressure gases and dangerous goods.
