Everllence, a marine engine developer, has upgraded a research test bench at its Augsburg site in Germany to enable hydrogen combustion as part of efforts to develop CO₂-neutral propulsion systems.
The work is being carried out under the HydroPoLEn project, a collaboration with industry partners and research institutes backed by Germany’s Federal Ministry for Economic Affairs and Energy through its Maritime Research Programme.
The initiative is focused on creating sustainable propulsion technologies for shipping.
Everllence said the project has successfully designed and tested a combustion process and engine components specifically for hydrogen use. The newly developed process allows for a significant increase in power density when running on hydrogen, addressing a key technical hurdle for the fuel’s adoption in marine engines.
Project partners include WTZ GmbH, the Technical University of Munich’s NMA institute and Tenneco, with Carnival Maritime acting as an associated partner. Dedicated hydrogen infrastructure has also been installed at the Augsburg site to support ongoing research and future development.
The company said hydrogen is expected to play an important role alongside other alternative fuels such as ammonia and methanol as the shipping industry evaluates multiple pathways to reduce emissions.
