DNV has awarded approval in principle (AiP) for liquid organic hydrogen carrier (LOHC) technology that will be used to power a ship.
The AiP is for Hydrogenius LOHC Maritime’s release unit which will discharge hydrogen from the benzyl-toluene liquid organic carrier on demand on the ship for use in a fuel cell.
The LOHC power system includes an LOHC release unit coupled with a PEM fuel cell to provide electrical power for a ship’s auxiliary power or propulsion.
Coming as part of the Enova-supported HyNjord project, the technology will be installed onboard Østenjø’s vessel Edda Ferd to trial a 200kW fuel cell propulsion system.
LOHCs are organic compounds that exist as liquids under ambient conditions and offer a potentially safe and relatively cheap hydrogen storage mechanism while remaining compatible with existing hydrocarbon infrastructure.
Hydrogen can be stored in and released from LOHCs through a hydrogenation/dehydrogenation process. For the hydrogenation process, an exothermic (release of heat) reaction must take place, while an endothermic (absorption of heat) reaction is required for the dehydrogenation process.
“With the HyNjord project, we will demonstrate the use of our LOHC power system as a real zero-emission alternative for ship power production,” said Øystein Skår, CEO of Hydrogenious LOHC maritime.
“We are very excited to receive the AiP from DNV for our innovative and first-of-its-kind project to bring hydrogen as a fuel onboard ships with our LOHC technology.”
