On 4th May 2024, Dutch shipyard Feadship unveiled Project 821, the world’s first hydrogen fuel-cell superyacht. This groundbreaking 2024 Feadship launch for Fuel-Cell Superyacht Project 821, over five years in the making, marks a significant step forward in the yachting industry. Designed by RWD, Project 821 is here to revolutionise the way we think about sustainable yachting.
Pioneering Green Technology
Project 821 is the first superyacht to embrace a zero-diesel approach, using green hydrogen to generate emission-free power for cruising between harbours and running the yacht’s amenities. This innovation is not just a step forward for the yacht itself, but for the entire industry. Feadship is committed to developing “net zero” yachts by 2030, which uses hydrogen fuel cells that produce only pure water as exhaust.
Challenges & Innovations
One of the major challenges in developing Project 821 was the safe storage of liquid hydrogen at -253°C. This required significant advancements in technology and regulations. The yacht’s cryogenic fuel tank, holding 92 m³ of hydrogen, is a testament to the engineering prowess involved. Additionally, the fuel cells on board are capable of using methanol, which offers flexibility in fuel sources.
Luxury Meets Sustainability
Beyond its green technology, Project 821 is a marvel of luxury and design. At 118.8 metres, it is the largest motor yacht ever launched in the Netherlands, surpassing even the 118-metre Launchpad. The yacht’s design features five decks above water and two below, with numerous openings that connect the interior with the sea, creating a seamless indoor-outdoor experience.
The owner’s deck spans four levels, offering a private, townhouse-like experience with luxurious amenities including two bedrooms, twin bathrooms, dressing rooms, a gym, offices, and a living room. The yacht’s interior design by RWD Studio features light, neutral colours and a luxe coastal vibe.
Technological Advancements
Project 821 is not just about luxury; it’s a technological powerhouse. The yacht is equipped with sixteen 185kW PowerCell H2 generators and can store 543 kWh of energy, allowing for a week of silent, emission-free operation at anchor. For longer journeys, the yacht’s MTU generators can burn HVO, a biofuel that reduces emissions by 90%.
The yacht also features cutting-edge amenities such as a central atrium-style staircase, a circular elevator, an 8.20-metre pool, and a sundeck with a hot tub. With accommodation for up to 30 guests, including eight VIP staterooms that can be combined, Project 821 offers unparalleled luxury and comfort.
The Future Of Yachting
By successfully integrating hydrogen fuel cells and cryogenic storage into a superyacht, Feadship has set a new standard for sustainability in the industry. As advancements in fuel cell technology and methanol-to-hydrogen conversion continue, Project 821 stands as a beacon of what’s possible when innovation meets commitment to a greener future.
