Four-stroke HydroPoLEn Partnership Marks Progress with Everllence hydrogen capable test bench
Everllence has taken a significant step forward in the development of CO₂-neutral propulsion technologies with the successful upgrade of a research-engine test bench at its facility in Augsburg to enable hydrogen combustion.
The achievement forms a key milestone in the ongoing HydroPoLEn project, a collaborative research initiative uniting Everllence with leading industry partners and academic institutions. The project is supported by the Federal Ministry for Economic Affairs and Energy through its Maritime Research Programme.
HydroPoLEn is focused on creating sustainable propulsion solutions for the maritime sector, addressing the urgent need for environmentally-friendly technologies in global shipping. Based on investigations, the project has designed and successfully tested a combustion process, mechanical components and parts specifically for hydrogen operation. In particular, the newly developed combustion process enables a significant increase in power density under hydrogen operation.
Project partners include Everllence, WTZ GmbH, NMA at the Technical University of Munich, and Tenneco, with Carnival Maritime acting as associated partner.
Furthermore, dedicated hydrogen infrastructure has been set up alongside the project in Augsburg, representing a significant milestone for the site. This infrastructure not only supports current research but also positions Augsburg as a key hub for developing future technologies.
Dr Cornelius Wagner – HydroPoLEn Project Manager – said: “We are still at an early stage in terms of developing a complete propulsion solution for the market, but this news augurs well for the future. Hydrogen poses significant challenges for engine operation and requires optimal adaption of safety systems and components for it to reach maximum potential. With these key challenges now addressed, hydrogen is moving closer to becoming a long-term solution for the defossilisation of passenger ships.”
Dr Matthias Auer – Head of Performance & Emissions, Four-Stroke R&D, Everllence – said: “In the race for future propulsion technologies in the maritime sector, hydrogen has a decisive role to play alongside ammonia and methanol. Since no single technology will likely prove optimal for all applications in the foreseeable future, companies must remain flexible and evaluate all options. Hydrogen will be an essential consideration in this context.”
Dr Alexander Knafl – Senior Vice President R&D Four-Stroke, Everllence – said: “With HydroPoLEn, we are taking another, major step forward toward climate‑neutral maritime transportation. Our hydrogen engine demonstrates that ingenious engineering is a key element for sustainable, carbon-free propulsion, providing the foundation for the next generation of marine mobility. We are extremely proud to drive forward solutions that unite environmental responsibility with strong industrial innovation.”
Everllence further states that the new development underscores its commitment to innovation and sustainability, paving the way for cleaner and greener propulsion systems in maritime applications.
