BREAKTHROUGH: Feadship’s 118.8-Metre Hydrogen Milestone

Feadship’s 118.8-metre **BREAKTHROUGH** is more than a record-sized Dutch build. It is a practical demonstration of how an ambitious owner brief can move alternative-energy systems from concept studies into an operational superyacht platform. According to Feadship, the project began with a direct owner question: what green technology could be incorporated into a full-custom yacht? The resulting engineering programme stores liquid hydrogen at approximately minus 253 degrees Celsius and uses sixteen PowerCell fuel-cell systems to generate three megawatts of electrical power. Water vapour is the stated exhaust from the fuel-cell process. The shipyard says the fuel-cell installation can support a week of silent hotel-load operation at anchor or propel the yacht at 10 knots in protected marine areas without using fossil fuel. Two rotating ABB azimuthing thrusters eliminate conventional shaft lines and rudders, contributing to lower vibration and a quieter onboard environment. The technical programme is paired with a highly connected guest experience. Fourteen retractable balconies, seven opening platforms and nine shell doors expand the relationship between the interior and the sea. RWD designed the exterior and interiors, while De Voogt Naval Architects developed the naval architecture. For the wider market, BREAKTHROUGH is significant because the owner and yard treated cleaner propulsion as a complete design requirement rather than an optional accessory. It offers shipyards, naval architects and future owners a full-scale reference for integrating new fuels, electric distribution and luxury-hotel loads in one vessel.
