RINA awards Freudenberg e-Energy Methods type-approval for methanol-powered gas cell system


Freudenberg has acquired Kind Approval by the worldwide classification society RINA for its methanol-powered gas cell system for ocean-going transport.

Changing industrial ships on the excessive seas to CO2-neutral drive techniques is a big problem. One vital issue is the vary requirement of the person ship sorts. This should be as massive as doable for cruise ships, tankers and container ships so as to have the ability to cowl the lengthy routes internationally’s oceans with out stopping. Route flexibility and ranges of greater than 5,000 nautical miles are primary necessities of the world’s maritime fleet.

Purely battery-electric options are sometimes out of the query for these deep-sea functions as a result of their excessive weight and area necessities. Hydrogen as a direct vitality storage medium can be dominated out for these ship sorts, as its low volumetric vitality density would require it to be saved in enormous hydrogen tanks in a cryogenic or extremely compressed state. This isn’t a sustainable possibility for the maritime business, Freudenberg says.

However, gas cells have great benefits as a result of their excessive effectivity and low upkeep necessities. Due to this fact, it is sensible to bind regeneratively produced hydrogen chemically to realize a considerably greater vitality density. It will make gas cells economically and virtually viable for ocean-going transport. The gas cell system might be flexibly mixed with a maritime battery techniques to create significantly environment friendly hybrid options.


On this context, using climate-neutral methanol represents a turning level on the highway to maritime sustainability and the achievement of IMO emission discount targets, Freudenberg posits.

Freudenberg e-Energy Methods has developed an strategy to utilizing methanol for marine functions that mixes extremely environment friendly gas reforming know-how with a long-life PEM gas cell in a modular, scalable system unit.

It generates hydrogen by way of steam reforming, which then reacts with oxygen from the air within the gas cell to supply {the electrical} vitality wanted for each propulsion and the ship’s electrical system. The warmth required for the reformer might be obtained immediately from the waste warmth of the gas cells. Gas cell stack, reformer and management electronics in addition to all elements for media provide are situated in a prefabricated, modular unit. This containment design facilitates simple set up on board.

The security idea of this technique structure has now acquired Kind Approval from the classification society RINA. This confirms the security of the system and its conformity with maritime requirements and laws.


Already optimized for heavy hundreds on the cell stage, the particular materials configuration of the bipolar plates (BPP) and the membrane electrode unit guarantee the required excessive effectivity and sturdiness required for heavy-duty functions.

Freudenberg’s security idea was already examined for maritime conformity in an early section of the “Pa-X-ell 2” analysis challenge. For this goal, it acquired “Approval in Precept” from the classification society DNV GL. Along with the give attention to the security idea, the subjects of modularization and standardization had been thought of in an effort to take account of the features of large-scale industrialization from the very starting.

Sooner or later, system models with a respective nominal output of 500 kW are to be mixed into whole capacities within the double-digit megawatt vary. Along with Freudenberg, the challenge consortium specializing in passenger transport consists of the companions Carnival Maritime (AIDA Cruises), Meyer Werft in addition to Lürssen Werft, besecke, DLR, EPEA and the classification society DNV GL.

The “HyFleet” analysis challenge launched in 2021 exhibits that the constant design technique with lifetime and effectivity as priorities can be effectively fitted to different segments. Along with its challenge companions ZF Friedrichshafen and FlixBus, Freudenberg is working to interchange standard diesel drives in long-distance buses. Preliminary take a look at outcomes present {that a} service lifetime of at the least 35,000 hours might be achieved. This corresponds to a complete service lifetime of 1.2 million km for a truck.

Freudenberg e-Energy Methods is a part of the worldwide Freudenberg Group, which has 4 enterprise areas: Seals and Vibration Management Know-how, Nonwovens and Filtration, Family Merchandise in addition to Specialties and Others. In 2021 the Group generated gross sales of greater than €10 billion and employed greater than 50,000 associates in round 60 international locations.
