The first superyacht to run on hydrogen from seawater

ITALY Thanks to hydrogen production and the use of hydroelectric turbines, the ONYX H2-BO 85 superyacht offers a luxurious trip with little ecological impact.

MASK Architects, an architecture firm based in Italy, reveals the design of ONYX H2-BO 85, an 85-meter-long hydrogen-powered superyacht, Design Boom reported on October 10. MASK Architects collaborated with Alchemist Studio to design this super yacht. Its interior shows modern luxury with unique design solutions.

ONYX H2-BO 85 was introduced as the world's first superyacht powered by hydrogen produced from seawater through electrolysis right on the boat (during the electrolysis process, water molecules split into hydrogen and oxygen). Superyachts are expected to usher in a new era of yachting sustainability, pioneering the delivery of luxury and eco-friendliness.

Combining hydrogen production with the use of hydroelectric turbines, the ONYX H2-BO 85 prioritizes sustainable electricity production for short trips, while minimizing environmental impact, aiming for zero emissions and reduced emissions. ecological footprint of boating.

The ship's hydroelectric turbine effectively exploits the kinetic energy of the surrounding water, thereby producing and storing hydrogen on board. This eliminates the need to store large amounts of fuel, providing clean and accessible power when the vessel is running at low speeds or at anchor.

Seawater taken from the environment undergoes pretreatment to remove impurities before electrolysis. Hydrogen produced from electrolysis will be stored in a suitable storage tank. Because this is a flammable gas, the superyacht also applies safety measures such as adequate ventilation, leak detection systems and a number of other procedures. Hydrogen is then used as a form of fuel for engines, generators or fuel cells.
