Supplying Hydrogen to Key Technologies

​

• PEM Fuel Cells: Hydrogen extracted from ammonia feeds Polymer Electrolyte Membrane (PEM) fuel cells.
  These cells generate electricity with only water as a byproduct, enabling silent, efficient, and emission-free operation.
   

• Ammonia Internal Combustion Engines (as Pilot Fuel): In engines adapted to run mainly on ammonia, hydrogen serves as a pilot fuel to enhance ignition, stability, and performance, ensuring reliable marine power with dramatically reduced emissions.
   

• Hydrogen Internal Combustion Engines: For vessels equipped or retrofitted to run on pure hydrogen, Pherousa’s technology provides a seamless and steady hydrogen supply derived from ammonia, supporting true zero-emission navigation.

Enabling Retrofit and Newbuild Solutions​

Pherousa’s ammonia cracking technology is designed with versatility in mind. It can be integrated into:
 

• 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.
