Proteus develops Maritime Fuel Cell Solution

Proteus Energy, headquartered in Singapore, announced it has developed the Proteus Maritime Fuel Cell Solution, a modular hydrogen fuel-based system for ports and vessels. The technology has been developed in partnership with Symbio France, a hydrogen fuel cell company jointly owned by Michelin, Stellantis and Forvia.

The first offering is the Proteus75. Each fuel cell stack has a 75-kW output and can be combined for larger power requirements. The Maritime Fuel Cell Solution can be delivered as a modular powerpack or customized and fitted into vessels.

Vessel types being targeted for the Proteus75 are harbor craft and those in the coastal, offshore support and inland waterway segments.

“The maritime industry needs viable clean energy solutions today,” said Dr. Lars Gruenitz, CEO of Proteus Energy. “We are providing a high energy density solution that is compact and lightweight, which is critical for vessels where space and weight considerations are imperative.”

The fuel cell stacks are produced at Symbio’s gigafactory in Lyon, France, with the Maritime Fuel Cell Solution backed by a two-year performance guarantee from Symbio France.

The Maritime Fuel Cell Solution is expected to be available for delivery beginning January 2026, with type approval from DNV anticipated before the end of this year.

Proteus also offers high-pressure hydrogen storage tanks developed with its partner Forvia, a global components and technology company. The DNV type-approved tanks, which are already available for delivery, are designed to offer a safe and easy way to store hydrogen onboard vessels and will be produced on an industrial scale.

In addition, the company works with port operators to provide them with customized refueling solutions and infrastructure.

“As regulators push towards zero emissions, ports and vessel operators face immense pressure to act now. With our proven technology and system designed for practical integration, we can assist our customers to meet their emission targets ahead of schedule and future-proof their business,” said Dr. Gruenitz.
