Italian shipbuilder Fincantieri will develop a hydrogen-powered cruise ship for Viking Cruises, which will use onboard hydrogen storage and PEM fuel cells.

Amogy Chief Strategy Office (CSO) Maciek Lukawski tells Edward Laity why the company’s first maritime demonstration will be its last.

The vessel features twin 12-cylinder hydrogen-blended ICE and a storage capacity of approximately 250kg of high-pressure hydrogen gas.

Rux’s storage solution uses a nanoporous material which works like a sponge, soaking up hydrogen inside storage tanks and increasing the density.

Featuring a dual-fuel hydrogen combustion engine co-developed by Cmb.Tech and Man, the 27-metre Hydrocat 60 can store up to 458kg of compressed hydrogen.

The vessel’s 2,700kW hydrogen fuel cell integrates battery storage, optimising efficiency by storing excess energy for low-load operations and boosting power during high-output demands.

New mandatory regulations for using hydrogen and ammonia fuel in ships are unlikely before 2028 at the earliest, according to a white paper by ships classification organisation DNV.

Wastewater from a nearby treatment plant is repurposed using Waterhelm’s technology to create reusable water, which is then electrolysed by Logan Energy’s systems to produce green hydrogen – providing clean shore power for berthed vessels.

The hydrogen was produced onboard the Winz Maru vessel and converted to MCH to facilitate safer and efficient handling and transportation.

Zepp.solutions will provide its X150 fuel cell modules to deliver power outputs exceeding 1MW in a retrofitted cruise vessel.
