Groundbreaking Vessel: World's Initial Hydrogen-Fueled Luxury Yacht (Superyacht) Named Project 821

Project 821, also known as "Breakthrough", is making waves in the world of luxury yachting. This groundbreaking 118.8-meter motor yacht, built by Feadship, is the world's first superyacht to run primarily on green hydrogen fuel cells[1][2].

Specifications

With a length of approximately 118.8 meters, a beam of 19 meters, and a draft of 5.05 meters, Project 821 boasts a gross tonnage of around 7,247 GT. The yacht features five decks above waterline and two below, offering accommodation for up to 30 guests in 12 staterooms and 44 crew members[1][2][4][5].

Benefits

Project 821's green hydrogen fuel system offers numerous advantages. During hotel load and coastal cruising phases, the yacht operates emission-free, significantly reducing its carbon footprint[2]. The yacht also incorporates advanced water recovery and heating systems, maximizing efficiency by heating floors, pools, and jacuzzis using recovered heat. Sensors adjust air conditioning and heating in unoccupied spaces to save energy, further enhancing its sustainability[1].

Technology and Innovation

The yacht's fuel system consists of a 3.2 MW fuel cell system powered by cryogenic liquid hydrogen stored at -253°C. Sixteen compact 185kW fuel cells provide enough energy for Project 821's battery bank. The battery bank acts as a buffer storage facility between the fuel cells and the twin 3,200kW electric ABB pod thrusters[1][2].

The superyacht uses electro-chemical fuel-cells to convert 'green hydrogen' into electrical energy. A pressurised double-wall cryogenic 92m2 fuel tank on board keeps hydrogen at its required temperature[1]. Project 821 can also function in a diesel-electric mode with five MTU generators, which can run off both conventional diesel or sustainable HVO biodiesel[1].

Design and Amenities

Project 821 is not just a sustainable vessel; it is a luxury yacht that offers the utmost comfort and style. The yacht features 14 balconies, 7 large opening platforms, pool and jacuzzi heating, and smart energy management systems for air conditioning and heating[1][2][4][5].

The owner's deck is a testament to personalised luxury, while multiple private lifestyle areas ensure a sense of exclusivity. Other features include a beach club, cinema, mini hospital, and an underwater 'Nemo' lounge tucked into the keel[1].

The Future of Sustainable Yachting

Project 821 represents a significant step forward in integrating green hydrogen technology at a large scale in luxury yachting. Its design is particularly suited to reduce emissions during frequent in-harbor and coastal operation phases, where most annual energy is consumed[2].

With a maximum speed of 17 knots and a fast-cruise range of 6,500nm at 14 knots, Project 821 is not just a symbol of sustainability but also a testament to the potential of green technology in the luxury yachting industry[1].

Project 821, now for sale through superyacht broker Edmiston, is a beacon of innovation and sustainability in the world of superyachts[2]. Despite the confidential price, it is estimated to be well north of half-a-billion euros[2]. This remarkable vessel is a testament to the possibilities of green technology and the future of sustainable yachting.
