Breakthrough

Feadship spent five years researching, designing, and constructing the world’s first hydrogen-fuel-cell superyacht. It involved rethinking the interior to accommodate 4.4 tons of liquid hydrogen—which required 10 times more space than what’s needed for diesel fuel and must be stored in cryogenic tanks at minus 253 degrees Celsius—to generate emissions-free energy. This technical leap combines 16 fuel cells, lithium batteries, two electric motors, and diesel generators to meet

Breakthrough’s substantial propulsion and hotel needs. It will also allow the behemoth to cruise on fuel cells for short periods. Its heat-recovery system warms the pool, jacuzzi, steam room, and floors and even preheats the engines. The luxe interior features elegant textured leather, marble, and rattan. The owner’s deck includes two en-suite bedrooms, a gym, two offices, and a living room, while a private book-lined staircase leads to the lower deck. Other unique features: a regulation-sized pickleball court on the bow and a submerged Nemo lounge on the lower deck.
