Proteus® Maritime Fuel Cell Solutions
Purpose-built for maritime environments, Proteus’ hydrogen fuel cell solutions offer clean, reliable, and efficient hydrogen power to drive the next generation of sustainable vessels.
Cutting-Edge Hydrogen Fuel Cells For All Vessels
Proteus® fuel cells utilise Proton Exchange Membrane (PEM) technology. This highly efficient and sustainable system generates electricity by using oxygen and hydrogen marine fuel, with water and heat being only by-products.
This zero-emission power source is low-maintenance, scalable, and adaptable for various vessel types, offering a future-ready alternative to conventional marine diesel engines, heavy fuel oil and LNG-powered systems.
Built For Maritime Conditions
Proteus® hydrogen fuel cells are designed by maritime experts to withstand harsh marine conditions,
providing reliable, high-performance power where it matters most.
Key Features
Zero Emissions
Proteus® fuel cells generate electricity with only water and heat as by-products, eliminating CO₂, NOₓ, SOₓ, and particulate emissions to meet global maritime decarbonisation targets.
High Energy Density
Quiet & Vibration-Free Operation
Unlike traditional combustion engines, Proteus® fuel cells operate silently, reducing onboard noise and vibration to improve comfort for passengers, crew, and the environment.
Low Maintenance & Operational Savings
With fewer moving parts than conventional marine engines, and lubrication oil use, Proteus® hydrogen fuel cells reduce maintenance costs while enhancing long-term reliability
Low-Temperature Operation
Proteus® fuel cells run at low temperatures, ensuring safe, efficient performance, faster start-up, and reduced system wear, even in demanding maritime conditions.
Future-Proof & Regulation-Ready
Compliant with IMO 2050 emissions goals, FuelEU and major classification society standards, Proteus® fuel cells provide a long-term, sustainable energy solution for the maritime industry.
