The first 'flying boat' model runs on hydrogen fuel cells

This year's World Cup international sailing competition will see the first flying boat run on hydrogen energy with a speed of 92.6km/h.

In 2012, the Emirates New Zealand (ETNZ) team competed in the US World Cup for the first time with the AC72 double-hull racing boat. Now, less than 10 years later, they've introduced another hydrogen fuel cell "flying boat" prototype called the Chase Zero. Last week, ETNZ released a demonstration video showing the Chase Zero testing around the Waitemata harbour in Auckland.

The Chase Zero is part of Project Hydro launched by ETNZ and the first racing boat of its kind to participate in the World Cup. It is 10 m long and can accommodate 6 crew members. With an underwater propeller design, ETNZ's racing boat looks like it's flying when it's on the move, as the hull is above the water.

The vehicle is equipped with two 80 kW Toyota hydrogen fuel cells, each housed in one side of the fuselage. To generate energy, hydrogen gas is passed through a catalyst that splits the H2 molecules and electrons. The generated electricity can be directly fed to the electric motors that propel the boat, or stored in batteries.

The Chase Zero is capable of long-distance running at 55.5 km/h with 160 kW generated from two fuel cells, or accelerating to 93.6 km with 420 kW in less time. The battery can be recharged when there is excess power.

"With its futuristic design, impressive features and zero carbon emissions, the Chase Zero is seen as a significant advancement in terms of clean renewable energy in the marine industry. It's basically just emissions. steam, which is amazing considering the positive impact on the environment," emphasized ETNZ CEO Kevin Shoebridge.
