While forging a path to zero emissions–this catamaran is skipping battery-powered boats and going straight to the cutting edge of tech, hydrogen-fuel-cell stacks!
As Cup defenders, the Kiwis were in charge of creating the new protocol for the 2024 event, for which they sought out areas desperate for new technology. “We realized our chase boats were years behind our foiling race boats,” says Nick Burridge, ETNZ’s operations and reliability manager. “To keep up, theETNZ decided to bypass battery-powered boats and move straight to the holy grail of zero emissions: hydrogen-fuel-cell stacks.
Despite its promise, the technology for the new Hydrogen Support Vessel needed to be proven before other teams would commit to multi-year Cup campaigns costing tens of millions, which required each to have at least one hydrogen-powered chase boat. The HSV’s specifications—10 meters in length, seats six people, a top speed of 50 knots and a four-hour range at 30 knots, plus the ability to carry 550 pounds of gear beyond passenger weight—also ratcheted up the pressure on the designers.
Consultants forecasted that mating untested propulsion with a sophisticated, software-controlled foiling system would take four years;hit the water after only nine months. “It exceeded expectations on day one,” says Burridge. “Now, the goal is to push this technology onto the world stage.” tender for another America’s Cup team, American Magic. Like ETNZ, Bluegame assembled dozens of experts in areas ranging from alternative propulsion to advanced structural composites .
Bluegame plans to incorporate fuel cells on larger yachts going forward, with a world-first hybrid-electric drivetrain being developed with partner Volvo Penta that utilizes a hydrogen fuel cell. “We’ll be launching it on a 65-foot multihull in 2026,” says Santella. “Hydrogen’s going to open up a new era for all of us.”
