MAN CRYO DEVELOPS MARINE LIQUID HYDROGEN FUEL SYSTEM

Wednesday, December 5, 2018 

MAN Cryo, the wholly owned subsidiary of MAN Energy Solutions, has in close cooperation with Fjord1 and Multi Maritime in Norway developed a marine fuel-gas system for liquefied hydrogen.

Multi Maritime’s hydrogen vessel design for Fjord1, including the fully integrated ‘MAN Cryo – Hydrogen Fuel Gas System’, has been granted preliminary approval in principle, (AIP), by DNV-GL, the first marine-system design to secure such an approval.

Dr Uwe Lauber, CEO of MAN Energy Solutions, said: “Winning this approval is a significant development for a number of reasons. As a solution for vessels employed on relatively short maritime routes, such as ferries, this technology is a world-first and showcases our company’s ability to deliver genuinely innovative solutions. Furthermore, Hydrogen is a clean fuel whose profile fits perfectly with the general desire within the industry to move towards cleaner technology. The possibilities for this technology are varied and exciting.”

MAN Cryo developed the Liquid Hydrogen Marine Fuel Gas System design in-house at its headquarters in Gothenburg in close cooperation with the shipowner, Fjord1, and ship designer, Multi Maritime, in Norway. Louise Andersson, Head of MAN Cryo, said: “To secure this approval in principle shows the determination that MAN Energy Solutions has to advance cleaner shipping solutions. Our strategy is to actively work with our customers to design and promote cleaner ways of powering vessels, and the competence and energy within MAN Cryo conveys this strategy excellently.”

The system has a scalable design that allows easy adaptation for different ship types, sizes and conditions. The design is suited for both above- and below-deck applications, offering designers the flexibility to optimise their designs in relation to efficiency, and to cargo or passenger space.

MAN Cryo has long experience with cryogenic gases and solutions for storage and distribution. The company has made numerous hydrogen installations over the years on land in addition to its experience with marine fuel-gas systems for LNG.

Liquefied hydrogen has a temperature of -253° Celsius and is one of the absolute coldest cryogenic gases, which places system components and materials under extreme stress. Another design challenge was hydrogen’s explosive nature, with the MAN Cryo engineering team accordingly placing top priority on safety.

Once liquefied, hydrogen is reduced to 1/800th of its volume, compared to that of its gas phase, facilitating a more-efficient distribution. As a fuel, hydrogen releases zero CO2 and can play an important role in the transition to a clean, low-carbon, energy system.

Liquefied hydrogen can be used to charge batteries for electrical propulsion via fuel-cell technology. MAN Cryo states that it sees a bright future for hydrogen applications globally as part of its target of achieving zero fossil emissions within the marine sector by 2050. Norway in particular is developing several promising hydrogen applications.

MAN Cryo claims a pioneering reputation within the marine sector and LNG business development. It supplied the first LNG fuel-gas system for the Glutra ferry in Norway in 1999, a vessel that is still operational. More recently, in 2013, MAN Cryo supplied the first bunker vessel, the SeaGas, operating in Stockholm. The design for the conversion of the SeaGas was provided by Multi Maritime with whom MAN Cryo has a long-time cooperation.
