Hydrogen Applications: Meeting IMO Zero-Emission Targets

Ammonia, cracked onboard to yield hydrogen, positions Pherousa’s technology as an enabler for zero-emission fuel cycles, aligning with International Maritime Organization (IMO) standards.

The versatility of onboard hydrogen production opens several pathways for reducing fossil fuel reliance:

​

• Blend with LNG: Hydrogen can be mixed with up to 20% of the liquefied natural gas (LNG) stream on existing vessels, further cutting emissions from LNG operations.

• Pilot Fuel for ICE Engines: Hydrogen serves as a pilot fuel for ammonia-powered internal combustion engines (ICE), enabling the complete elimination of fossil fuels onboard.

• Supplying PEM Fuel Cells: Hydrogen produced onboard can feed proton exchange membrane (PEM) fuel cells, supporting both:

  • Replacement of older auxiliary engines, enhancing efficiency and lowering greenhouse gas output.

  • Full electric main propulsion, providing a zero-emission pathway for vessel propulsion.
    ​

By offering solutions for both retrofitting existing ships and powering new builds, Pherousa’s technology maximizes its impact across the maritime sector

​​

• Retrofitted Existing Fleet: By retrofitting current vessels with ammonia crackers and compatible engines or fuel cells, shipowners can dramatically cut emissions without the need for entirely new ships. This approach supports the rapid decarbonization of the global fleet and extends the useful life of existing assets.
   

• Newbuild Vessels: For shipyards and owners investing in new ships, Pherousa’s systems can be incorporated from the design stage, optimizing efficiency and sustainability from day one.

Reducing Emissions from Auxiliary Engines
 

Beyond main propulsion, applying ammonia cracking technology to auxiliary engines and generators offers substantial emission reductions. Even if the main engines remain unchanged, retrofitting auxiliary systems with hydrogen-supplied fuel cells or engines can significantly lower a vessel’s overall carbon footprint during operations at berth or anchor.
