DNV has awarded approval in principle (AiP) for LOHC technology that will power a ship. The AiP is for Hydrogenius LOHC Maritime’s release unit, which will discharge hydrogen from the benzyl-toluene liquid organic carrier. The hydrogen will be used on demand in a fuel cell onboard the vessel.

LOHC Power System for Ship Auxiliary Power and Propulsion

The LOHC power system includes an LOHC release unit paired with a PEM fuel cell. It is designed to provide electrical power for a ship’s auxiliary power or propulsion. This technology is being developed as part of the Enova-supported HyNjord project. It will be installed on Østenjø’s vessel Edda Ferd to trial a 200kW fuel cell propulsion system.

Advantages of Liquid Organic Hydrogen Carriers

Liquid organic hydrogen carriers (LOHCs) are organic compounds that exist as liquids under ambient conditions. They offer several advantages as a hydrogen storage mechanism:

  • Potentially safe and relatively cheap hydrogen storage
  • Compatibility with existing hydrocarbon infrastructure

Hydrogen can be stored in and released from LOHCs through a hydrogenation/dehydrogenation process. The hydrogenation process involves an exothermic reaction (release of heat). The dehydrogenation process requires an endothermic reaction (absorption of heat).

Demonstrating Zero-Emission Alternative for Ship Power Production

Øystein Skår, CEO of Hydrogenious LOHC maritime, expressed excitement about receiving the AiP from DNV. “With the HyNjord project, we will demonstrate the use of our LOHC power system,” stated Skår. “It is a real zero-emission alternative for ship power production.” He added, “We are very excited to bring hydrogen as a fuel onboard ships with our LOHC technology.”

The approval from DNV marks a significant step forward in the development and implementation of LOHC technology. It offers a promising solution for reducing emissions in the maritime industry for hydrogen-powered vessels.
