The contract has been awarded to Aqualisbraemar LOC Group by Caledonian Maritime Assets Ltd (CMAL), one of the partners in the EU-funded HySeas III programme.
The plan is to demonstrate that hydrogen fuel cells can be successfully integrated with a marine hybrid electric drive system, along with the hydrogen storage and bunkering arrangements.
Fuel cells of this type are currently used in road transport and can be found in hundreds of hydrogen-fuelled buses across Europe.
The HySeas III project will develop, construct, test and validate data in a full-sized drive train, the group of components that make up a motor vehicle, on land.
If successful, it will pave the way for the first seagoing vessel that uses this fuel technology.
