MED Group has revealed more details of the 12-meter TYKUN H1, a hydrogen-powered, ready-to-build dayboat designed for fast cruising and full-day autonomy. Developed by the aluminum performance chase boat specialist, the H1 draws on the expertise of TESYA Group, which engineered the hydrogen propulsion systems used on the 37th America’s Cup chase boats, with design by Tommaso Spadolini. The all-electric tender is capable of speeds of up to 35 knots, a cruising speed of 20 knots, and a range of up to 60 nautical miles, powered by a hydrogen fuel cell. Fully engineered and type-approved, the H1 features a user-friendly hydrogen system and is supported by the NatPower H refueling network. “The TYKUN H1 project began with a key challenge — to produce a hydrogen tender that was usable and manageable for a customer,” said Ugo Casadio, chief technical officer at MED Group. “We were lucky enough to make the acquaintance of the TESYA Group team, who had just come from producing the chase boats used in the last America’s Cup. Key to the H1 project was to translate this experience into a boat that more mainstream customers could enjoy.” The H1 functions as an electric boat powered by a battery bank that drives electric motors, with a fuel cell using gaseous hydrogen as a range extender to recharge the batteries. A standard shore power connection allows fast charging, enabling the H1 to operate as a high-performance electric tender even in areas where hydrogen is not available. Hydrogen is stored in four concealed tanks holding approximately 32 kilograms at 350 bar, with refueling taking just three minutes. A simplified piping system delivers the hydrogen to the fuel cell, which converts it into electricity with only water as its emission. NatPower H supports the project through its growing network of port- and marina-based hydrogen refueling points, as well as mobile services, currently operating 40 sites worldwide. “The goal was to introduce a boat that was easy to operate and manage, while also delivering the style and customization of our TYKUN dayboats and superyacht tenders,” Casadio said.
