Hydrogen-Powered Future: Proteus Unveils Maritime Fuel Cell Solution
A new era in clean maritime propulsion is underway as Proteus Energy launches the Proteus® Maritime Fuel Cell Solution, a modular hydrogen-based energy system designed specifically for ports and vessels.
Backed by industrial giants Michelin, Stellantis and Forvia, and developed in partnership with Symbio France — a world leader in hydrogen fuel cell technology — the Proteus system promises compact, high-performance, zero-emission power for a range of vessel types.
Compact, Scalable and Ready for the Sea
The first unit, Proteus®75, delivers 75 kW per stack. These can be combined for higher power requirements and are ideal for:
- Harbor craft
- Offshore support vessels
- Coastal and inland waterway vessels
CEO Dr Lars Gruenitz explains:
“The maritime industry needs clean, scalable solutions today. Our system delivers high energy density in a compact and lightweight package — essential for vessels where space and weight are at a premium.”
Proven Technology from Land to Sea
Symbio’s fuel cells, already proven across millions of road kilometers in Europe, now enter the maritime market. Backed by a two-year performance guarantee, these systems offer:
- Zero tailpipe emissions
- Minimal noise and vibration
- Fast refueling
- Low maintenance
- Superior energy retention vs. batteries
Perfect for full-electric or hybrid vessels, Proteus’ system extends operational range and reduces battery load.
Industrial-Scale Reliability
Produced at Symbio’s gigafactory in Lyon, each fuel cell stack benefits from automotive-grade precision and scale, allowing Proteus to meet rising demand with consistent quality. Over 2,000 fuel cell membranes are tested annually to ensure continuous performance upgrades.
Advanced Hydrogen Storage & Refueling Solutions
Proteus also offers DNV type-approved hydrogen storage tanks, co-developed with Forvia. Built for marine use and already available for delivery, these tanks enable safe, high-pressure storage on board.
In parallel, Proteus is collaborating with port authorities to roll out customized refueling infrastructure — making hydrogen a practical alternative for today’s maritime operations.
Deployment Timeline
- Type approval from DNV expected by the end of 2025
- First deliveries available January 2026
As regulatory pressure increases, Proteus positions itself as a key enabler of maritime decarbonization.
“We’re not just developing clean tech — we’re delivering practical solutions that help operators meet emissions targets and secure their future,” concludes Dr Gruenitz.
