What makes this offering stand out is its compact form factor and high energy density—key factors in maritime settings where space is at a premium. Hydrogen's fast refueling times, lower maintenance needs, and long-term energy storage advantages give it an edge over battery alternatives in certain marine environments. Unlike batteries, hydrogen tanks don't lose energy when idle, making them a practical option for intermittent usage cycles.
Proteus has tailored its system for the marine environment, leveraging automotive-grade technology refined through years of on-road testing. The system minimizes onboard vibration and noise, while helping operators meet growing regulatory demands around emissions reductions.
Proteus Energy’s solution is backed by an industrial-scale supply chain, thanks to its collaboration with Symbio France—a company jointly owned by Michelin, Stellantis, and Forvia. Symbio brings 30 years of hydrogen experience, with its fuel cell systems already logging millions of kilometers in cars, trucks, and buses across Europe.
This automotive credibility translates to robust quality assurance for marine operators. Symbio conducts testing on more than 2,000 fuel cell membranes each year, with ongoing updates to improve durability and performance. All units in the Proteus maritime system are built using high-precision, robotic production lines at Symbio’s gigafactory in Lyon, ensuring consistent output and readiness to scale with demand.
In addition to fuel cells, Proteus integrates high-pressure hydrogen storage tanks into its system offering. These tanks—developed in collaboration with Forvia—come with DNV type approval and are already in production. The company also works directly with port operators to implement tailored refueling infrastructure, removing one of the biggest barriers to hydrogen deployment in maritime applications.
The system includes a two-year performance guarantee, with full type approval anticipated before the end of 2025. With emissions rules tightening across the shipping sector, the Proteus Maritime Fuel Cell Solution is positioned as a practical route to future-proofing vessel operations.
