MAN Cryo’s hydrogen fuel-gas system given AiP

The scalable system can be adapted for different ship types, sizes and conditions and is suitable for both above- and below-deck applications, providing naval architects with design flexibility.
Liquefied hydrogen is one of the coldest cryogenic gases, with a temperature of -253° Celsius, and is highly explosive. Temperature stress and safety have therefore been top priorities for the MAN Cryo engineering team. As a fuel, hydrogen does not release any carbon dioxide and can be used to charge batteries for electrical propulsion, using fuel cell technology.
"Winning this approval is important for a number of reasons," said Dr Uwe Lauber, CEO of MAN Energy Solutions. "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."
