Proteus Launches Modular Hydrogen Fuel Cell System for Maritime Sector

Singapore-based Proteus Energy has announced the development of its modular hydrogen fuel cell system designed specifically for maritime applications. The Proteus® Maritime Fuel Cell Solution, launched in collaboration with French hydrogen technology leader Symbio, aims to accelerate decarbonization in harbor craft, offshore support vessels, coastal transport, and inland waterway operations.

The first product in the range, Proteus®75, delivers 75 kW per fuel cell stack, with scalability to accommodate larger power needs through modular integration.

Symbio, jointly owned by Michelin, Stellantis, and Forvia, brings over three decades of hydrogen fuel cell expertise to the partnership. Its systems, which have accumulated millions of kilometers powering vehicles across Europe, are now adapted for marine use, complete with protections for maritime conditions and supported by a two-year performance guarantee.

“The maritime industry urgently needs practical, clean energy solutions,” said Dr. Lars Gruenitz, CEO of Proteus Energy. “Our system offers high energy density in a lightweight, compact design, making it ideal for vessels with strict space and weight constraints.”

Key Features and Benefits:

  • Zero tailpipe emissions
  • Minimal noise and vibration
  • Low maintenance due to fewer moving parts and no oil consumption
  • Rapid refueling compared to battery charging
  • Stable long-term hydrogen storage without energy loss

Proteus’ technology also supports hybrid vessel applications, enhancing electric propulsion systems by reducing battery load, extending operational range, and improving vessel efficiency.

Built on Proven Platforms

Fuel cell stacks for the maritime solution are produced at Symbio’s gigafactory in Lyon, France. The facility uses advanced robotic systems to manufacture thousands of units annually, ensuring both quality and scalability.

This industrial capacity allows Proteus to offer reliability and performance consistency at a global scale—capabilities typically associated with established players in the automotive hydrogen sector. Symbio also tests over 2,000 fuel cell membranes each year, accelerating innovation and long-term system optimization.

Hydrogen Storage and Infrastructure

To complement its fuel cell systems, Proteus provides high-pressure hydrogen storage tanks developed with technology partner Forvia. These DNV type-approved tanks are ready for delivery and will be manufactured on an industrial scale. Proteus is also working with port authorities to develop tailored refueling infrastructure for streamlined operations.

“As global regulations tighten around emissions, both ports and vessel operators face rising pressure to decarbonize,” Dr. Gruenitz added. “Our marine fuel cell solution offers a practical, proven pathway to meet compliance targets and secure long-term operational sustainability.”

Commercial Rollout

Proteus expects the fuel cell solution to be commercially available from January 2026. DNV type approval is anticipated by the end of 2025. The company is currently engaging with customers for early integration planning.
