world's first 85-meter superyacht powered by onboard hydrogen production from seawater

mask architects conceptualizes energy-efficient cruising

International firm MASK Architects unveils ONYX H2-BO 85 — the world’s first superyacht propelled by onboard hydrogen production harvested from seawater. This 85-meter-long vessel combines electrolysis with hydroelectric turbines to provide a sustainable power solution for short cruising distances, minimizing environmental impact. In this way, the ONYX H2-BO 85 emits no harmful gases locally, significantly enhancing the marine environment and reducing the yacht’s ecological footprint.

Hydroelectric turbines efficiently capture kinetic energy from surrounding water, outperforming conventional generators in energy efficiency. This clean energy approach enables the yacht to generate and store hydrogen onboard, eliminating the need for large fuel reserves and providing easily accessible energy during low-speed sailing or anchoring.

ONYX H2-BO 85 utilizes seawater for electrolysis

In response to the maritime industry’s growing emphasis on sustainability and emission reduction, MASK Architects’ ONYX H2-BO 85 is the world’s first superyacht to be powered by its own hydrogen production. Consequently, this reduces the yacht’s reliance on fossil fuels, resulting in substantial long-term cost savings amid rising fuel prices and stable hydropower costs.

Within, from opulent cabins to lavish lounges, each space radiates modern elegance, offering passengers a luxury onboard experience with bespoke design solutions. Renowned interior designers have together curated every detail, combining refined material palettes, cutting-edge technology, and sustainable elements to create an inviting and eco-conscious ambiance.
