MAN Cryo has provided a fuel supply system to a 118.8-meter hydrogen-powered superyacht built by Dutch company Feadship. This project, called “Project 821,” has become the world’s first hydrogen fuel cell-powered superyacht.
The first hydrogen-powered superyacht by MAN Cryo
The system developed by MAN Cryo will store hydrogen in liquid form, transform it into a gas and supply it to the fuel cell, enabling the ship’s propulsion without generating polluting emissions. This division of MAN Energy Solutions specializes in engineered solutions for cryogenic equipment used in the storage and handling of gases.
Although hydrogen fuel cells have been commercially available for more than sixty years, their application in the maritime sector has been limited. The technology employed in Project 821 allows the superyacht to operate silently for an entire week while at anchor, or sail emission-free at a speed of 10 knots, with pure water as the only emission.
“This achievement demonstrates MAN Energy Solutions’ leadership in creating fuel systems of the future for the maritime industry. MAN Cryo is setting new standards in sustainability with its innovative system design and strategic placement of the fuel tanks below deck. We congratulate Feadship on its commitment to decarbonization and driving sustainability in the superyacht segment.”
Henrik Malm, Managing Director, MAN Energy Solutions Sweden
MAN Cryo faced several challenges during project development, mainly due to the lack of hydrogen-specific codes and design standards. Type C LNG tanks, generally designed to IGF code, were not fully applicable. Therefore, MAN Cryo collaborated with Lloyd’s Register to create a design based on the risk assessment, which was approved for installation below deck, the first of its kind worldwide and the second for a marine liquid hydrogen project.
The system supplied by MAN Cryo for the superyacht includes a 92 m³, vacuum-insulated C-type tank capable of storing liquid hydrogen at -253 degrees Celsius, a tank connection space (TCS) with the necessary process equipment, a refueling station to load liquid hydrogen from shore to the ship, and control and automation systems. In addition, the ‘tank prediction tool’ simulates pressure and fill levels, assisting the crew in planning refueling operations. Moreover, the system includes a ventilation mast and hydrogen piping interconnection.
